Sfc126 "Sync_Pi - Datalogic AMT58*-PN Series Instruction Manual

AMT58x-PN ProfiNET®
The assigned process image partitions must be updated in the
synchronous cycle interrupt OB61 at the call of the functions SFC126
"SYNC_PI" and SFC127 "SYNC_PO".
The call of the function SFC126 "SYNC_PI" updates the process
image partition input table; the call of the function SFC127
"SYNC_PO" updates the process image partition output table. So
cyclic interrupt OB61 works with consistent image of the process
signals. Refer also to page 108.

11.5.2 SFC126 "SYNC_PI"

This special function is used to update a process image partition
input table in a synchronous cycle.
Synchronous cycle interrupt OB61 calls the function SFC126
"SYNC_PI" to consistently and synchronously update the input data
located in a process image partition.
11.5.3 SFC127 "SYNC_PO"
This special function update a process image partition output table in
a synchronous cycle.
Synchronous cycle interrupt OB61 calls the function SFC127
"SYNC_PO" to synchronously update the output data located in a
process image partition and consistently transmit them to the
encoder.
