10.5 Interface in the User Program
10.5.1 FC Call Interface
Changing Call Parameters only after Job Confirmation
Notice
After a job has been triggered, you may only change the call parameters on the
FC call interface of the FCs AG_SEND or AG_RECV again after the FC has
confirmed job execution with DONE=1 or ERROR=1.
If this is ignored, it is possible that the execution of the job will be aborted with an
error and resources could be permanently occupied on the CPU.
10.5.2 Use of SFB 54 RALRM in PROFINET IO
When using SFB54, the optional fields “Vendor ID” and “Instance ID” are not
supplied in the data structure for the TINFO parameter (bytes 28 to 31). You
should remember this when evaluating the data.
10.5.3 Programmed Communication Connections with FB55
IP_CONFIG
Downloading the Configuration using FB55
FB55 allows program−controlled transfer of the configuration data.
Note
If the CP is in PG STOP mode, the configuration is downloaded using FB55, the
CP then changes automatically to RUN.
