2.10.6 Scenario 4b – Communication via parameterized OUC (single
instructions) and CP1543-1
Prerequisite
Loaded
S7-1500 station
Enable bit S7-1500 CPU
for scenario 4b
Activated enable bit
(S5-CPU)
PLC_Sz4_S-R_CP_ID4_ID104
E 0.2
M 130.1
Activate the corresponding enable bit in the SIMATIC S5-CPU via the "BB1” watch
table.
As, in this case, the S7-1500 program contains the two example scenarios 4a and
4b, activate scenario 4b via the enable bit E 0.2.
Now, the connection will be established by the SIMATIC S5 station.
Test and diagnostics of communication in the SIMATIC S7-1500
The bidirectional data exchange (continuous count value) can be monitored via the
output byte (AB0) of the S7-1500.
To monitor the ongoing communication and the status of the send and receive
blocks in the SIMATIC S7-1500, call the watch table "BEO_Sz2_ID4” in TIA Portal.
