Power Connectors and Wiring

The FieldDAQ device has two 5-pin L-coded M12 power connectors, power IN and power OUT. The power connectors provide one voltage line (V), one common line (C), chassis ground, and two lines for optional auxiliary power, Aux1 and Aux2.

The following figure shows the power circuitry on the FieldDAQ device.

Figure 1. Power Circuitry

1378

The FieldDAQ device requires an external power source connected between the V and C terminals, as described in Power Requirements in the FD-11613 Specifications. The FieldDAQ device internally connects the C terminal to the chassis ground. Recommended NI power supplies are listed in FD-11613 Basic Information.

The FD-11613 has a maximum device power consumption of 4.9 W. Each FieldDAQ filters and regulates the supplied power for its tasks.

When FieldDAQ devices are linked together through the power IN and power OUT connectors, the total current consumption of the chain equals the sum of every linked FieldDAQ device’s current consumption. The total current cannot exceed 10 A, and the total supply load of the chain must be less than 300 W.

You can use the optional auxiliary power lines (Aux1 and Aux2) to draw power for non-FieldDAQ devices in your network. The FieldDAQ device does not make use of the auxiliary power itself. If you are connecting power through the auxiliary power lines, ensure that the total combined current between V Input and Aux power lines does not exceed 10 A.

Refer to the FD-11613 Specifications for information about the power connectors, power requirements, and current limits of your FieldDAQ device.

Cap the power connectors when not in use.

  3. Carefully align and connect the cable to the external power source and the power IN connector on the FieldDAQ device.
  4. Turn on the external power source.

If the power source is connected to the power connector using long wiring with high DC resistance, the voltage at the power connector may be significantly lower than the specified voltage of the power source.

Refer to Power Requirements in the FD-11613 Specifications for information about the power supply input range. Refer to Safety Voltages in the FD-11613 Specifications for information about the maximum voltage from terminal to chassis ground.

Thermocouple Connectors and Measurements

The following figure shows thermocouple circuitry of the FD-11613.

Figure 8. FD-11613 Block Diagram

1378

The FD-11613 provides channel-to-channel isolation.

  • Input Impedance—Each channel has a resistor that produces an input impedance between the TC+ and TC- terminals. The gain and offset errors resulting from the source impedance of connected thermocouples are negligible for most applications. Thermocouples with a higher lead resistance can introduce more significant errors.

  • Open Thermocouple Detection—Each channel has an open thermocouple detection (OTD) circuit, which consists of a current source between the TC+ and TC- terminals. If an open thermocouple is connected to the channel, the current source forces a full-scale voltage across the terminals and the Open Thermocouple LED lights red.

    Refer to the Open Thermocouple Detection (OTD) topic in the NI-DAQmx Help for more information about how this feature is used in the NI-DAQmx API.

  • Timing Modes—The FD-11613 supports the following timing modes:
    • High-resolution optimizes accuracy and noise and rejects power line frequencies.
    • Best 50 Hz rejection optimizes 50 Hz noise rejection.
    • Best 60 Hz rejection optimizes 60 Hz noise rejection.
    • High-speed optimizes sample rate and signal bandwidth.

    Refer to the FieldDAQ Timing Considerations topic in the NI-DAQmx Help for more information about configuring timing in the NI-DAQmx API.

  • Filter, Differential Amplifier, and ADC—Each channel simultaneously passes through a filtered, differential amplifier before being sampled by a 24-bit ADC.

The FieldDAQ device provides overvoltage protection for each channel; refer to the FD-11613 Specifications for more information about overvoltage protection.

Thermocouple Connectors

The FD-11613 features eight thermocouple connectors. The following figure shows the pinout of a thermocouple connector.

Note When you turn off the LEDs in MAX, the FieldDAQ device controls and sets the state of the LED. You cannot configure an LED while a task is running.

Thermocouple Connection Guidelines

The following figure shows a general connection diagram.

Figure 10. Connection Diagram

1378

Notice To protect against ESD, water, and dirt, install unconnected mini-TC plugs into all unused terminals, and install FD-11940, Mini-TC Connector Protection Boot (Qty 8) (NI part number 786394-01) on all mini-TC plugs.
Notice If your application is subject to high vibration or shock, NI recommends 0.5 mm2 (20 AWG) or larger thermocouple wire. Strain relieve all cables as close to the device as possible.

Make sure that devices you connect to the FD-11613 are compatible with the device specifications. Refer to your thermocouple documentation or the thermocouple wire spool to determine which wire is the positive lead and which wire is the negative lead.

Minimizing Thermal Gradients

Changes in the ambient air temperature near the front connector or a thermocouple wire conducting heat directly to terminal junctions can cause thermal gradients. Observe the following guidelines to minimize thermal gradients and improve the system accuracy.

  • Use small-gauge thermocouple wire. Smaller wire transfers less heat to or from the terminal junction.
  • Run thermocouple wiring together to keep the wires at the same temperature.
  • Avoid running thermocouple wires near hot or cold objects.
  • Minimize adjacent heat sources and air flow across the terminals.
  • Keep the ambient temperature as stable as possible.
  • Make sure the FieldDAQ device terminals are facing forward or upward.
  • Keep the FieldDAQ device in a stable and consistent orientation.
  • Allow the thermal gradients to settle after a change in system power or in ambient temperature. A change in system power can happen when the system powers on, or you add or remove devices from a network topology.
  • Allow the thermal gradients to settle after plugging or unplugging the mini-TC plugs.

Thermocouple Measurement Accuracy

Thermocouple measurement errors depend partly on the following factors:

  • Type of thermocouple
  • Accuracy of the thermocouple
  • Temperature that you are measuring
  • Resistance of the thermocouple wires
  • Cold-junction temperature

For the best accuracy performance, set up the FD-11613 according to Setting up the FieldDAQ Device and Thermocouple Connection Guidelines to minimize thermal gradients across the terminals.

Programming the FieldDAQ Device

You can use the FieldDAQ device in the following analog input applications:

  • Single-point acquisition
  • Finite acquisition
  • Continuous acquisition

The FieldDAQ device features the following timing and triggering signals:

For more information about programming analog input applications and triggers in software, refer to the NI-DAQmx Help or the LabVIEW Help for more information.

AI Sample Clock Signal

A sample consists of one reading from each channel in the AI task. Sample Clock signals the start of a sample of all analog input channels in the task. Refer to the following figure for sample clock source options.

Figure 11. AI Sample Clock Timing Options

1378

The FD-11613 is specifically designed for measuring signals that vary slowly. Because of their slow rate, it is not appropriate for these devices to constrain the AI Sample Clock to operate at or slower than their maximum rate. When using the FD-11613 in the same task as faster devices, the maximum Sample Clock rate can run faster than the maximum rate for the device. When operating at a rate faster than the it can support, the FD-11613 returns the same point repeatedly, until a new conversion completes. In a hardware-timed task, the first point is acquired when the task is committed. The second point is acquired after the start trigger as shown in the following figure.

Figure 12. Sample Clock Timing Example

1378

AI Sample Clock Timebase Signal

The AI Sample Clock Timebase signal is divided down to provide a source for Sample Clock.

AI Start Trigger Signal

Use the Start Trigger signal to begin a measurement acquisition. A measurement acquisition consists of one or more samples. If you do not use triggers, begin a measurement with a software command. Once the acquisition begins, configure the acquisition to stop in one of the following ways:

  • In finite mode, when a certain number of points has been sampled
  • In continuous mode, with a software command

You can specify a default delay from the Start Trigger to the first sample.

Use the Start Trigger signal with a time source, by specifying a specific time in NI-DAQmx. Refer to the Time Triggering topic in the NI-DAQmx Help for more information on accessing time-based features in the NI-DAQmx API.

Time-Based Triggers

FieldDAQ devices feature automatic network-based synchronization with compatible networks and IEEE 802.1AS-capable NI Linux Real-Time controllers. The SYNC logo on the device front panel indicates that the device is capable of hardware-based synchronization over a network.

FieldDAQ devices can be daisy-chained together or connected to external networks that support IEEE 802.1AS synchronization, and all device timebases will be automatically synchronized. Refer to Synchronization across a Network for more information about supported topologies and other technical requirements.

Network-synchronized devices can also take advantage of time-based synchronization features in NI-DAQmx. Certain triggers can be specified in terms of time of day. Time-based triggers and multidevice tasks (spanning multiple network-synchronized FieldDAQ devices) can help simplify programming for large systems.

Time triggers can be specified in Host Time or I/O Device Time, depending on the needs of your application.

  • I/O Device Time—The time the FieldDAQ device uses internally. This time is determined by the network configuration and is shared by all IEEE 802.1AS network-synchronized devices on your subnet.
  • Host Time—The time on your Windows computer or NI Linux Real-Time controller. This is usually the current global time and is provided by a local real-time clock or a network time protocol (NTP) server.

NI-DAQmx automatically translates from Host Time to I/O Device Time as necessary. The accuracy of this translation depends on the relationship between these times and can reduce the relative accuracy of time triggers across multiple devices. For maximum accuracy, use an NI Linux Real-Time controller as the host in a supported topology. However, NI-DAQmx guarantees that two tasks configured to start at the same host time always start at the same I/O Device Time in all scenarios, preserving precise synchronization between chassis in this common use case. Refer to the Time Triggering topic in the NI-DAQmx Help for more information on accessing time-based features in the NI-DAQmx API.

Timebases

The following figure shows the FD-11613 clock routing circuitry and timebases.

Figure 1. Clock Routing Circuitry

1378

You can use the 80 MHz, 20 MHz, and 100 kHz timebases to generate the measurement signals. The 80 MHz timebase is generated directly from the onboard clock generator. The 20 MHz and 100 kHz timebases are generated by dividing down the 80 MHz timebase.

Refer to the FieldDAQ Timing Considerations and Master Timebase Synchronization topics in the NI-DAQmx Help for more information about configuring timing in the NI-DAQmx API.

Synchronization across a Network

The onboard 100 MHz oscillator automatically synchronizes to other network-synchronized devices that are part of your local IEEE 802.1AS subnet.

The 80 MHz, 20 MHz, and 100 kHz Timebases are derived from the oscillator, and are synchronized to it. Therefore, they are also synchronized to other network-synchronized timebases on your 802.1AS subnet. This enables measurement signals to be synchronized to other devices across a distributed network.

The FieldDAQ devices use the IEEE 802.1AS protocol over the network to synchronize. They can be configured to use the IEEE 1588-2008 protocol profile instead.[1]

Ethernet Ports and Networking

The Ethernet Network Interface transfers data between the FieldDAQ device and the network. It gathers the data into TCP/IP packets that can be sent across the network and interpreted by the host.

Note Refer to Setting up the FieldDAQ Device or Connecting to a Real-Time Controller for information about connecting the FieldDAQ device to a host computer or host real-time controller.

Ethernet Ports

The FieldDAQ device has two 8-pin X-coded M12 Ethernet ports—0 and 1. You can use a shielded straight-through Ethernet or an Ethernet crossover cable with either of the Ethernet ports to network your device to a computer host, NI Linux Real-Time controller, another FieldDAQ device, or any network connection on the same subnet. Refer to Topology Options for more information about using these ports in various topologies.

Internal Ethernet Switch

The FieldDAQ device features a full hardware-accelerated internal Ethernet switch for greater performance, wiring flexibility, and compatibility over standard Ethernet ports. The Ethernet switch exposes two Ethernet ports to the user. Either port can be used to connect the device to the network. The two ports can be used to connect multiple devices in a daisy-chain topology. The switch also supports the Rapid Spanning Tree Protocol (RSTP) algorithm, enabling ring topologies. Refer to Topology Options for more details.

IEEE 802.1AS-2011 Precision Time Protocol

The internal Ethernet switch is an IEEE 802.1AS time-aware bridge, compatible with the IEEE 802.1AS-2011 Precision Time Protocol. It can synchronize local measurement signals to other devices across an IEEE 802.1AS subnet. It can also serve as a bridge, synchronizing IEEE 802.1AS devices that are attached to each of the two ports. Refer to Synchronization across a Network for more details.

IEEE 802.1Q Rapid Spanning Tree Protocol (RSTP)

It is possible to create loops in a network using the FieldDAQ device. To prevent these loops from disrupting the network, the FieldDAQ device implements the IEEE 802.1Q Rapid Spanning Tree Protocol (RSTP). Using this protocol, each FieldDAQ device can find the shortest path for incoming packets to reach the rest of the network. When multiple paths exist, this adds a form of redundancy. If a link fails, the protocol automatically switches to use the redundant link. This process can take several seconds in some cases.

To gain these benefits on external switches connected to the FieldDAQ device, IEEE 802.1Q (RSTP) must be enabled. All external switches must be configured to allow the FieldDAQ device to transmit RSTP packets, known as Bridge Protocol Data Units (BPDU). If any switch has a feature—such as “BPDU guard”—enabled, the port connected to the FieldDAQ device is disabled and communication is lost. Refer to the documentation for your external switch for information about enabling RSTP and disabling BPDU guards on the switch.

IEEE 1588-2008 Protocol

The internal Ethernet switch can be configured to act as a 1588 "boundary clock" implementing the IEEE 1588 delay request-response default PTP profile (sometimes referred to as "default profile"). When so configured, it can synchronize local measurement signals to other devices across an IP subnetwork and can serve as a bridge, synchronizing 1588 devices that are attached to each of the two ports. Refer to Synchronization across a Network for more details.

Note The IEEE 802.1AS protocol is an IEEE 1588 profile, but is incompatible with other IEEE 1588 profiles. When FieldDAQ devices are using the IEEE 802.1AS protocol to synchronize they cannot synchronize with devices that use other protocols or IEEE 1588 profiles and vice versa.

The FieldDAQ device is associated with two MAC addresses—both of which are labeled on the device—device and switch. These MAC addresses are not associated with a particular Ethernet port, but both addresses can appear on both ports as necessary.

Table 9. NI MAX Device and Switch MAC Addresses
Device MAC Address Switch MAC Address
Associated with the device's IP address Associated with the internal Ethernet switch—not associated with the device’s IP address
Used by normal device traffic Used for Ethernet protocols for network configuration and synchronization
Listed in MAX Not listed in MAX

The switch MAC address is used to implement the following switch protocols:

  • IEEE 802.1AS-2011 (Precision Time Protocol)
  • IEEE 802.1Q (Rapid Spanning Tree Protocol [RSTP])
  • IEEE 1588-2008 (Precision Time Protocol)[2]

The switch MAC address only appears in packets exchanged between the switch embedded in the FieldDAQ device and the next Ethernet device. It will not propagate further in a properly configured network. For more information about the recommended configurations for networking the FieldDAQ device, refer to Topology Options.

Topology Options

Recommended networking topologies are described in this section.

  • Host—Can be a Windows computer or a real-time controller with the NI Linux Real-Time operating system, such as the IC-317x, cRIO-9035/9039 Sync, cRIO-904x/905x, or cDAQ-9132/9133/9134/9135/9136/9137 for LabVIEW Real-Time
  • Node—Can be any FieldDAQ device or IEEE 802.1AS-compliant CompactDAQ chassis, such as the cDAQ-9185/9189

For more information about designing Ethernet measurement systems, visit ni.com/info and enter fdenet.

Line Topology

In a line topology—also known as daisy-chaining or bus topology—the host communicates directly with all nodes through one bus line. A standard Ethernet device or switch can be added to the end of the chain if desired and used as normal. Be aware that these devices will compete for network bandwidth with the FieldDAQ device. Reliable system design requires awareness of the bandwidth consumed by each device during operations. This topology offers no redundant links.

Figure 15. Line Topology

1378

Advantages:

  • Simple and inexpensive installation, expansion, and troubleshooting
  • Ideal for low number of nodes. NI recommends a maximum of 15 nodes.
  • No external switch needed
  • Can cover long distances

Disadvantages:

  • Any unpowered nodes and/or node failure disrupts network communication
  • Addition or removal of any node disrupts network communication
  • Failure of any Ethernet cable and/or improper cable termination disrupts network communication
  • Network performance and synchronization affected when node count exceeds 15. Consider the Star Topology for systems that require a greater number of nodes.
Note For information about daisy-chaining power, refer to Power Connectors and Wiring.

Ring Topology

In a ring topology, the host communicates with all nodes through the most effective path. You must use an external switch in a ring topology. You must configure the network properly with a recommended external switch before creating redundant links in the network. Refer to External Switch Requirements for information about what to look for in an external switch.

Figure 16. Ring Topology

1378

Advantages:

  • Failure of any single Ethernet cable does not disrupt network communication
  • Additional nodes or heavier network traffic affects network performance less than the line topology
  • Simple installation
  • Ideal for a local networking solution
Note Network configuration and programming require careful consideration. Visit ni.com/info and enter fdenet for information about exploiting link redundancy and automatically improving reliability.

Disadvantages:

  • Network traffic patterns can make troubleshooting difficult
  • Requires an external switch
Note For information about daisy-chaining power, refer to Power Connectors and Wiring.

Star Topology

In a star topology, the host communicates directly with each node through the external switch. You must use an external switch in a star topology; for network synchronization, you must use an external IEEE 802.1AS switch. Redundant links are recommended, but optional, in this topology. You must configure the network properly with a recommended external switch before creating redundant links in the network. Refer to External Switch Requirements for information about what to look for in an external IEEE 802.1AS switch.

Figure 17. Star Topology

1378

Advantages:

  • Unpowered nodes and/or node failure does not disrupt network communication with other nodes
  • Failure of any single Ethernet cable does not disrupt network communication when you have a redundant link
  • Additional nodes or heavier network traffic affects network performance less than the other topologies
  • Simple installation, expansion, and troubleshooting
Note Network configuration and programming require careful consideration. Visit ni.com/info and enter fdenet for information about exploiting link redundancy and automatically improving reliability.

Disadvantages:

  • Most costly of the recommended topologies
  • Requires an external switch (external IEEE 802.1AS switch for network synchronization)
  • Covers the least distance
Note For information about daisy-chaining power, refer to Power Connectors and Wiring.

Other Topologies

For information about designing Ethernet measurement systems for synchronization, visit ni.com/info and enter fdenet.

External Switch Requirements

To meet the minimum requirements for successful operation with FieldDAQ devices, any switch directly connected to the FieldDAQ device should be compliant with IEEE 802.1Q bridges and bridged networks.

To take advantage of the network synchronization and network redundancy features of the FieldDAQ device, ensure that your network infrastructure meets certain requirements:

  • IEEE 802.1AS-2011 time-based synchronization support—Automatically synchronizes timebases and enables the use of time-based triggers and multi-device tasks between device across the network.
  • IEEE 802.1Q (Rapid Spanning Tree Protocol) support—Supports network redundancy functionality in ring and star topologies
    • Rapid Spanning Tree Protocol (RSTP) enabled
    • Bridge Protocol Data Units (BPDU) Guard disabled

To learn more about recommended network switches and other network configuration best practices and requirements, visit ni.com/info and enter fdenet.
