Citect/SCADA Modbus Driver - where to set a Slave ID number?

[mykelse]

Hi,

I know you can set this somewhere, but unable to find it in the help. I'm sure i've done it many years ago before.

Where can you set a Modbus Slave ID?

I'm not getting any values from a Modbus slave device from Citect.

I get a #Bad status on the displayed tags.

Which parameter of Ports or Boards do we set it?

Anyone know?

Cheers.

Hi @mykelse,

The I/O Device (Unit) Address field is typically where you would define the "Station number" of your Modbus device.

So in Plant SCADA (Citect) Studio, you go to Topology, I/O Device, then Address field.

Hope this helps.

Kind regards

Olivier
