Modbus TCP issue with Schneiders Harmony device

Ignition
1

I am trying to configure a Harmony hub via modbus TCP and it look like its not working and I can’t figure out why. I tested it with modbus doctor and I do get some values back.

But in ignition I got this :

ignition_ss
ignition_ss1263×629 96 KB

This is what the manual say about addressing , I am reading a type 4 device which is a temperature sensor on input 1. (10+33*1 = 43 so I should have a value of 4 returned since I have a type 4 device)

I tried many register and many ways but still nothing :frowning:

I did set the driver as modbus tcp , port 502 and the IP and the right IP .

Am I doing smt wrong ? :face_with_monocle:

Try:

HRI43
1.HRI43
Go to advanced section of device properties, try 1 based setting and reverse word order

The temperature is a single word at +6 beyond that, and the test app shows slave # 248. Try:

[testRod]248.HR49

And note its unit is 0.01°C.

As mentioned all over the forum, don’t use Address Mapping, it’s not gonna help.

Have a good read of the following and see if you can use the examples to match the addresses you are trying to access.

Explaining which registers and unit IDs you are using also will help us.
