Enables notification of a specific type of event.
The resource to be used.
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
The logical event identifier.
Name | Value | Description |
---|---|---|
Service Request | 3FFF200B | A service request is received from the device or interface associated with the given session. |
Trigger | BFFF200A | A trigger interrupt is received from the device. This may be either a hardware or software trigger, depending on the interface and the current session settings. |
PXI Interrupt | 3FFF2022 | A PXI interrupt occurs. |
Serial Break | 3FFF2023 | A break signal is received. |
Serial TermChar | 3FFF2024 | The termination character is received. You can specify the actual termination character by selecting VISA Properties. | from
Serial CTS | 3FFF2029 | The Clear to Send (CTS) line changes state. If the CTS line changes state quickly several times in succession, not all line state changes necessarily result in event notifications. |
Serial DSR | 3FFF202A | The Data Set Ready (DSR) line changes state. If the DSR line changes state quickly several times in succession, not all line state changes necessarily result in event notifications. |
Serial DCD | 3FFF202C | The Data Carrier Detect (DCD) line changes state. If the DCD line changes state quickly several times in succession, not all line state changes necessarily result in event notifications. |
Serial RI | 3FFF202E | The Ring Indicator (RI) input signal is asserted. |
Serial Character | 3FFF2035 | At least one data byte is received. Each data character does not necessarily result in an event notification. In other words, if multiple data bytes arrive at once, you may get only one event. |
USB Interrupt | 3FFF2037 | A USB interrupt occurs. |
VXI Signal | 3FFF2020 | A VXIbus signal or VXIbus interrupt is received from the device associated with the given session. |
VXI/VME Interrupt | BFFF2021 | A VXIbus interrupt is received from the device associated with the given session. |
Default: Service Request
The resource to which a VISA session is opened.
This output also includes the class for the session, which matches that of session in.
