I’m trying to connect Micrologix1400 ser B controller to Ignition using Modbus TCP driver.
I have configured the channel 1 in PLC to a correct IP address and enabled Modbus. In Modbus TCP configuration I have defined a file for the holding registers and left the default port 502.
In Ignition, I’ve added a Modbus TCP device, gave it a name and IP address. However, after saving new device, Ignition can’t connect to it. Device’s status is changing between “Connecting” and “Disconnected”.
When I reconfigure the channel in Micrologix not to use Modbus, with all other settings left the same, I can connect to the Micrologix using the Micrologix driver in Ignition. Sadly, for this application I must use Modbus.
I would kindly ask for advice regarding this.
