Modbus TCP - Stuck at connecting

Ignition
1

Hello All, This is my first project with Ignition. Trying to Connect Modbus PLC using Modbus TCP connection
I am trying to connect to a MODBUS device using the following details:

  • IP Address: 10.101.150.38
  • Registers: 400001, 400002
  • TCP Port: 502
    The status is changing from Disconnected to Connecting but not connected.
    Configuration is attached in the picture. Can someone please help me. Thank you!

Don't both using the address Mapping.

Just make an OPC tag and set its OPC server to the Ignition native server, and try the following as possible OPC Item Paths:

[deviceName]HR1
[deviceName]1.HR1

If either of those work, but appear to not have the right data, you may need to play with some device advanced settings. (Zero-based addressing.)

If you then want to work with multi-register values (floats, 32-bit integers), use the manual addressing syntax for the combination you want:

You may also need to tweak the word order advanced setting on the device.
