SLC5/04 comms

Hi all

I have 2 SLC5/04 plcs and a scada connected on DH+.
I need to add a HMI which only has DH485 of DF1 available,
I can connect to the DF1 port on 1 of the PLC's, my question is, will I be also able to access the 2nd PLC through the same port? (bridge to the DH+)

Thanks in advance

If your HMI's driver supports target addresses on DF1, then you can configure DH+ Passthrough and access both SLC-5/04 controllers.

It won't be as fast to the 2nd controller as to the one you are physically connected to, but it can work.

then you can configure DH+ Passthrough and access both SLC-5/04 controllers.

Here's how..

Thanks, I'll give that a try.
