Integration into process stations

There must be a communication interface free in the process station. Typically, it is a serial port. In some cases, a RS232/RS485 converter (e.g. M012) must be used. If a PC-based process station (e.g. IPCT.1) has no free serial port available, it may be created using a terminal server (M020, M031), which creates a virtual serial port available over the Ethernet network. If there are standard protocols used, a Modbus RTU/TCP router, or M025 (RS232), M035 (RS485), M036 (RS485, at a lower price, as it does not work as a terminal server – Modbus RTU/TCP router only) is a good solution.
