Hello everyone,

I need your advice and help,

I have 10 plcs and one main scada. I read ten s7connection with PLCs. My scada is advice v19.

I want to add a communication schema on scada. It will show us which plc is connected or not. When a plc is down, I will a alert and alarm on scada.

How can I do?

I can read plc memory clock bits, example m0.7 clock 0.625Hz. I need to control this bit is changing. Do I need to a VB?

Hi,

What is your WinCC Runtime version? Is it Runtime Professional?

If so, you could use the System diagnostics views / controls:
