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

2 Engineering
Scenario 2a – Communication via parameterized OUC (single
2.10.2
instructions) and internal CPU interface
Prerequisite
Table 2-30
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, you can activate scenario 2a via the enable bit E 0.1.
Now, the connection will be established by the SIMATIC S7 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 (AB1) 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_ID105" 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.
1. In TIA Portal of the station, call the "Device configuration" of this scenario.
2. Go to the station in "online" mode via the "Go online" option in the menu bar.
3. In the "Network view" (1), select the station "PLC_Sz2_S-R_CPU_ID105" (2)
and go to the "Connections" tab (3).
4. In the "Connections" tab (3), select the parameterized ISO-on-TCP connection
with the local ID "105".
5. In the "Diagnostics" tab, go to the "Connection information" (4).
