Scenario 2B - Communication Via Programmed Ouc (Single Instructions) And Internal Cpu Interface - Siemens SIMATIC S5 Manual

2 Engineering
Scenario 2b – Communication via programmed OUC (single
2.10.3
instructions) and internal CPU interface
Prerequisite
Table 2-31
S7-1500 station
PLC_Sz2_S-R_CPU_ID5_ID105
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 2a and
2b, activate scenario 2b 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_ID5" in TIA Portal.
Please refer to the "online" help for error states or status displays of the OUC
blocks.
The status of the connection can also be checked in the S7-1500 station by means
of the online functions of TIA Portal (see chapter 2.10.2).
