Figure 5: System Setup
For this white paper we will use VeriStand as the software which will interact with the SLSC. To do this user will need to install VeriStand on the Host Computer and the Target. The host, target and SLSC maybe on the same network or separate networks as shown in figure 4.
For this section we will first describe using the SLSC-12201 Plugin Custom Device.
Using the SLSC-12201 Plugin Custom Device
To use the SLSC-12201 module in VeriStand, the user will need to install an SLSC plugin custom device on the system.
SLSC-12201 Custom Device example.
After the plugin is installed, the user should see the adapter SLSC plugin:
Figure 6: Using the SLSC-12201 Custom Device in VeriStand
SLSC-12201 Plugin allows the user to configure the digital lines on the SLSC-12201 as inputs or outputs. In this case the user should configure the lines as inputs and specify a threshold from 4 V with the range going up to 27.5 V and should correspond to the external reference.
Figure 7: Configuring the SLSC-12201
The line signals should be connected to a compatible R series module as described in section 4. The R series module can be programmed to measurement the pulse signal timing. For more information see Using The SLSC Architecture To Add Additional Elements To The Signal Path of a Test System.
Using the SLSC Electronic Datasheet Custom Device
Since the SLSC-12251/2 are more simple devices the user can download and use the SLSC Electronic Sheet Plugin Custom Device (EDS). This is a generic SLSC Module Custom Device which reads the module capabilities of any SLSC module and provides the user with a simple user interface for communicating with the module parameters.
SLSC EDS Custom Device
The following screenshot show how you can use the SLSC EDS Plugin Custom Device to access an SLSC-12251/2
Figure 8: Assigning Plugin Custom Devices to a Slot in the SLSC
Firstly, the user should allocate which slots in the SLSC will use the SLSC EDS Custom Device. The SLSC EDS Custom Device with then read the capability file stored on the SLSC modules, in this case the SLSC-12251/2, and will populate the tree with the module properties and channels as shown below.
Figure 9: Configuring the SLSC-12251/2 to connect to a load on deployment
The user can then configure the SLSC-12251/2 to connect lines through FIU to the load by changing the “NI.FIU.Preset.Load” from “NoLoad” to “Load”. Once the system deploys it will then automatically connect to the load and will disconnect from the load when the system undeploys.
Figure 10: Connecting to a load on deployment
Figure 11: Configuring the state of the load relay after undeploy
The SLSC-12251/2 can be configured to maintain the same state after undeploy setting the “Modify Reset Value?” to “Load”. Care should be taken to ensure that the system is safe since under these conditions.
Figure 12: SLSC-12251/2 Temperature Sensors
The SLSC-12251/2 has 4 temperature sensors and these can be used to read the temperature at different 4 quadrants of the module (see the SLSC-12251/2 User Manual for more information on placement of the temperature sensors). These channels, and other channels, are available for monitoring during operation however you can remove channels which will not be required by selecting the property and clicking on remove.
Figure 13: Removing channels from properties
The screenshot below shows how you can specify Alarms on a channel. In this case, an Alarm is generated when the maximum temperature reaches or exceeds 50 degrees Celsius.
