So an update just came out yesterday which changed the communication protocol version. You probably installed the reactor PLC app on unit 2 after the update, since the version in the bottom left of your unit 2 PLC doesn't match the version of your other one as shown on the supervisor.

You need to run ccmsi update <app> on each device (ex: ccmsi update reactor-plc), then it'll all connect. Updating all devices is only required when the comms version changes, but is still recommended either way.

it back to normal now Thankyou so much i will keep checking on update

I want to clarify that now that your devices all have a compatible comms version, they'll keep working regardless of new updates coming out. It's just that once one of the devices is updated by you or a new version is installed on a new device, you'll need to update the others if there was a comms version change (it'll tell you that when updating, but it can't when installing since it doesn't know what you have on the others).

That yellow light on the Reactor PLC, RTU Gateway, or Coordinator will indicate that the supervisor has a different comms version than that device.
