Autonomous system, process station with a touch screen (c, d)

For IPCT.1, a RS485/RS232 converter must be added, e.g. M012.

At some applications, more serial ports are used, such as
COM1   for I/O modules to control the primary plant (boiler room, AHUs)
COM2   for integration of individual room controllers, e.g. UC100

Each port must be connected over a separate M012 converter.

The process station may not be placed close to the controlled technology, it may be (incl. the converter) located at the operator’s place and the converter is connected to the I/O modules in the panel over a RS485 bus.
