Ethernet Communication (ISO on TCP) between SIMATIC S5 and
SIMATIC S7-1500 Controllers
Entry-ID: 109482475, V1.2, 07/2019
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.
