Digital input/output block
The digital I/O block defines a trigger model block that sets the lines on the digital I/O port high or low.
To set the lines on the digital I/O port high or low, you can send an output line bit pattern. The pattern
can be specified as an integer value, or, if you are using the TSP command set, a six-bit binary or
hexadecimal. The least significant bit maps to digital I/O line 1 and the most significant bit maps to
digital I/O line 6.
The bit mask defines the bits in the pattern that are driven high or low. A binary 1 in the bit mask
indicates that the corresponding I/O line should be driven according to the bit pattern. To drive all
lines, specify all ones (63). If the bit for a line in the bit pattern is set to 1, the line is driven high. If the
bit is set to 0 in the bit pattern, the line is driven low.
For this block to work as expected, make sure you configure the trigger type and line state of the
digital line for use with the trigger model (use the digital line mode command). The digital line settings
are only available through remote commands.
When you select the digital I/O block, the following options are available.
Setting Description
Out Line Pattern
Sets the value that specifies the output line bit pattern (0 to 63)
Out Line Mask
Sets the output line bit mask (0 to 63)
Log event block
This block allows you to log an event in the event log when trigger model execution reaches this
block. You can also force the trigger model to abort with this block. When the trigger model executes
the block, the defined event is logged. If the abort option is selected, the trigger model is also aborted
immediately.
You can define the type of event (information, warning, abort model, or error). All events generated by
this block are logged in the event log. Warning and error events are also displayed in a popup on the
front-panel display.
Note that using this block too often in a trigger model could overflow the event log. It may also take
away from the time needed to process more critical trigger model blocks.
When you select the Log Event block, the following options are available.
Setting Description
Event Type
The event number or type:
• Abort Model: Stop the trigger model and log a warning
message
• Information N: Logs an information message in the event log
• Warning N: Logs a warning in the event log
• Error N: Logs an error in the event log
Where N is 1 to 4; you can define up to four of each type
Message
A message that you define
