I have a Teledyne Isco Flow meter connected via Modbus TCP that keeps dropping out every few seconds from Ignition. I have pinged it from the local network with no issues and pinged it from the ignition network with no issues but in my OPC devices it goes from "Connected" to "disconnected" and reconnecting every few seconds.
I set my port to 1700 as it says in the manual and double checked my IP. I am using the Modbus TCP driver. Everything good there. Has anyone else had issues with these units?
Do you have any tags configured for the device in Ignition? Many modbus TCP devices will kill connections within a few seconds unless they see active requests coming through (Automation Direct BRX CPUs do this)
Also, port 1700 is not the standard Modbus TCP port, so double check your ignition server firewall is not blocking requests. (Probably not an issue if the device is reading 'connected')
A 10-second idle timeout is extremely common. Make sure at least one tag is subscribed at a faster pace.
