"Using wincc software to control and display the status of circuit breakers"
An I (such as I0.0) point is input into the PLC monitoring PLC to monitor the state of the circuit breaker, and a Q (such as Q0.0) point is relayed to the corresponding circuit breaker control loop.

WINCC is equipped with a circuit breaker, which directly connects the foreground color to I0.0. For example, when I0.0 is 0, the green i0.0 is 1, showing red.

Regarding control, it is enough to program Q0.0 in PLC, I0. 1 fault DB3. DBX 12.0 (any point that can be built in any data block can be built by itself).

Make a button to connect directly in WINCC. The address is DB3. DBX 12.0 0, when disconnected, connect at 1.

This premise is whether it is I0.0 or DB3. DBX 12.0 should create variables under the configuration connection corresponding to WINCC.
