4.3 Time-based IO
Reaction to error
The Error output indicates if the instruction was processed correctly. The reasons for the
errors are displayed at the Status output.

Description
Starts the job at a positive edge.
Hardware identifier for TIO module from HWCN.
Number (0 ... m) of the digital output of the connected
TM Timer DIDQ
System time provided for the TIO instructions of the TIO
modules by the TIO_SYNC instruction. See UDT
"TIO_SYNC_Data" (Page 57).
Connect this input parameter with the "TIO_SYNC_Data" output
parameter of the TIO_SYNC instruction.
Specify the output mode for the edges at the digital output:
0 : Output only positive edge (TimeStampRE).
D
1 : Output only negative edge (TimeStampFE).
D
2 : Both edges are output (TimeStampRE and TimeStampFE).
D
3 : Each edge is output directly when TimeStampRE = 0 or
D
TimeStampFE = 0. If both time stamps have the value "0" or if
no time stamp has the value "0", no edge is output.
4 bis 255 : Reserved
D
T : Time for output of isochronous output data.
o
Apply T from the ET 200 station (properties of the PROFINET
o
interface).
Time stamp: Time when a positive edge is to be output.
Time stamp: Time when a negative 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.
BUSY = True: The job is not complete yet.
DONE = True is displayed for one cycle: The job is signaled as
"done, no errors".
Status of the instruction: see description of Status parameter
If True, this output indicates that 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 remedied.
