SCADA to MASTER and SLAVE PLC communication

Hi,

I have two PLCs connected each other, one is Master whose station ID is 1 and the other is Slave whose Station ID is 4.

By connecting SCADA to Master PLC will it be possible to get the Tags from Slave PLC?

What sort of PLCs are they, if they are true redundant processors then they may swap station ID automatically, if not, you could write code to do this.
Secondly some SCADA systems will allow redundancy so perhaps that’s worth looking at. What sort of SCADA system is it?

Thanks Chris,

No, they are not redundant, ok so I have to go for a code, fine.

I'm using Labview as SCADA.
