[Support] How to keep Unity HSBY PLC ModBus Add 1 in both?

[leofarhan]

Hello,

I have Quantum Unity Hotstandby PLCs 140CPU67160, with built in ModBus Port.
Both ports are connected to two ModBus Masters separately,
When I am unchecking the ModBus Serial Address Swapping then PLC-A have the address 1, while the PLC-B have address 129.
I want to keep both the PLC-A and PLC-B address as 1. (Note both PLCs are connected to separate masters via separate cables)

Can you please guide, how to configure same address on ModBus Serial in Quantum Unity Hotstandby PLC?

Thanks & Regards,

Leo-Ali

it's easy, just use %SW60.8=1

Hello,

It is easy to stop address swapping, but then how can I change the address of both PLCs to 1.

Even if I download the application in the PLCs by removing the check box of ModBus Serial Address Swapping, Even then the Primary PLC will have Address 1 and standby PLC Address 129.
