Technical data

Programming example of reading out the DP station list and updating
DP group messages
FB202 "STAT-LIS" makes all DP group messages available by means of bit
formal operands.
If a slave leaves the cyclic data transfer phase, the DP station list is read
and saved in data block DB202 from DW0 onwards.
Description of the FB202 "STAT-LIS" formal operands:
STAF : DP station failed
DIAG : New DP diagnostic data exist
ZYGC : Cyclic global control job active
TOUT : Timeout processing the DP polling list
Function block FB202 with the corresponding data block DB202 for use in a
CPU of the S5-115U series is in the STEP 5 file STATIOST.S5D on the
COM/application example diskette.
