MODBUS Communication Practice: Communication Between Multi-Point Temperature Acquisition Module and Honeywell PKS System (Case Study: Temperature Acquisition Retrofit Project for PVC Plant)
Overview:The implementation method involves connecting field thermocouples to the temperature acquisition module, which connects via RS-485 to a serial server. The serial server converts the RS-485 signal to Modbus TCP protocol, allowing the DCS to collect data from the serial server. Main Tasks: Configuration of the multi-point temperature acquisition module; configuration of the serial server; … Read more
