I hope this will find you well!
I’m trying to connect to a Modbus TCP enabled battery to retrieve data from it. I checked first the good connection through the tool “Simply Modbus”. As it can be noticed, the communication has succeed and the data have been well transmitted.
However, when I created OPC server tags using Modbus TCP driver in ignition, I always find null values (note that the device is well connected) :
The OPC item path that I use is for instance:
226 is the UnitID, 259 is the modbus address for the variable “Battery Voltage”.
Could anyone help me please to fix this problem.
