Kepware is unable to read PLC tags

Hi Developers,

I have installed Twx Industrial Connectiveity 8.3 version. I have activated the license for Manufacturing Suite. Kepware is unable to read PLC tags

 

Background Work : 
1. We are using Delta PLC with RS485 Modbus protocol 
2. The PLCs are connected through a MOXA NPORT 2150 Wifi gateway. 
3. Kepware is configured with the IP address of the MOXA device and is in the same network. MODBUS TCP/IP and MODBUS ASCII drivers have been tried. 

Thanks and Regards,

Saran

Re: Kepware is unable to read PLC tags

The RS485 connection is an indication that this is a Modbus serial protocol, not Modbus TCP/IP.

 

You would want to select the Modbus RTU Serial driver using Ethernet encapsulation as the connection type to communicate to the Moxa's IP address.

Hi @aservetas,

 

Thanks for your reply. One of my teammate was able to successfully connect to the server. Seems we had made a mistake with the tag address.
