TIO_IOLink_OUT: Output time-controlled process output signals
Description
You can use Time-based IO with the TIO_IOLink_OUT instruction. TIO_IOLink_OUT lets you
activate the output data of an IO-Link Device at a specified time.
The IO-Link Device must be equipped with the time stamp function and the Port must be in
"IO-Link, Time based OUT" mode.
Startup characteristics
During startup of the CPU, the instruction TIO_IOLink_OUT applies the input parameters
once and checks the following:
● Checking HWID
● Checking whether the Port number is in the range (1 to 4)
● Checking TIO_SYNC_Data.Error: Is an error present at TIO_SYNC?
● Checking T
o
for a positive value
● Checking the setting to type IO-Link
● Checking Port mode regarding configuration for IO-Link Time based OUT
● Checking whether the OB is a "Synchronous Cycle" OB
● Checking PortQualifier
If startup takes place without errors, the instruction changes to normal operation. The input
parameters REQ , Out_Mode, TimeStamp and AA_Data can be changed during normal
operation. In the event of an error, the instruction does not change to normal operation and
generates an error message.
