I want to read some energie value by using modbus rtu over tcp in ignition. Summarly, we have an energie analyzer and modbus-ethernet gateway. they are connected each other with modbus rtu and I added that gateway to the our ethernet network by giving an IP address. I can see and add that gateway to the our ignition server and I am able to see that gateway as connected.
Now I want to read a value from analyzer which is connected to that modbus-tcp gateway. To be honest, I really do not hands on experience in reading data over modbus and tcp.
in the above picture, I see the some params that are wanted from me to read.
Also, in the picture above, we see the addresses snipping from the modbus device.
So what should I enter to read for example Voltage LN1 ? I tried to enter some values to that fields but I cannot read a value yet. I will be appreciate if somebody can help me ?
