Just downloaded the software and thought I had an easy project to start with. Took awhile to grasp the Tag hierarchy but think I have it.
My problem is this: Trying to setup VT to read from a Modbus TCP slave. I have tested the slave communication with a small Modbus TCP app, running on the same PC as the VT app and it works fine.
The ModBus TCP communication parameters are:
Slave IP address – 192.168.1.247
Slave Listening Port - 502
Slave Unit ID – 100
Slave Data Type – 03 Holding Register
Slave Registry Address/DataType - 843/uint16
All I want to do is read information from the above connection information and display it with a gauge. Every attempt has resulted in an Error 257
Once I get one gauge working I can get on with the rest of the project.
Any help will be greatly appreciated.
