I have to integrate 10 Modbus RTU Slaves on RS-485 (I can also use a gateway for TCP) with Allen-Bradley PanelView Plus (1000) FactoryTalk View screen. A-B PV+ will act as a Modbus Master.
What is the best way to do this without using Kepware OPC?
Options I thought:
1. Develop a .NET program running on PV+ (somehow!!) that implements Modbus Master and read/write data to a file and develop another VB script that runs within FTView to write/read the same file.
2. Develop a FTView Driver for Modbus Master that directly integrates Modbus Slave (both on RTU and TCP).
3. Develop a small OPC server that runs on PV+ (somehow!!) that provides data to FTView, much like the Kepware, but a much smaller and probably cheaper than Kepware. Time is not an issue, but cost-effectiveness is.
Please think through the request, and my options and kindly provide your view on my options and/or your suggestions.
Many Thanks.
