Description
Starts the job at a positive edge.
Hardware identifier for TIO module from hardware
configuration
Number (0 ... m) of the digital output of the connected TIO
module
Specify the output mode for the edges at the digital output:
0: Only rising edge is output (TimeStampRE).
1: Only falling edge is output (TimeStampFE).
2: Both edges are output (TimeStampRE and
TimeStampFE).
3: Each edge is output directly if TimeStampRE = 0 or
TimeStampFE = 0 If both time stamps have the value "0" or
if no time stamp has the value "0", no edge is output.
4 to 255: Invalid
Time stamp: Time when a positive edge is to be output.
Time stamp: Time when a falling edge is to be output.
Actual status of the digital output.
If an inversion of the digital output is configured, StatusDQ
is inverted as well.
StatusDQ shows the internal state of the digital output
independent of the effect of any configured HW enable.
DONE = True is displayed for one cycle: The job was
completed without errors.
BUSY = True: The job has not yet been completed.
Error = True: An error has occurred. In this case, BUSY and
DONE are set to False. For detailed information see Status
parameter.
Error is reset as soon as the error is corrected.
Status of the instruction: see description of Status
parameter
System time provided for the TIO instructions of the TIO
modules by the TIO_SYNC instruction. See UDT
TIO_SYNC_Data (Page 58).
Connect this parameter with the TIO_SYNC_Data output
parameter of the TIO_SYNC instruction.
