2.5.2 P1/HMI (RS485/RS422/RS232) Wiring
The P1/HMI port of PMC-592 is a DB9 Female connector since Hardware V1.01.00 and can be used as a
RS-232/422/485 port since Firmware V1.00.04. It is typically used to work with one of two optional
Display Modules: a 7” Touch-Screen HMI or a small Dot-Matrix LCD display (with limited display
capability). The P1/HMI port supports the Modbus RTU protocol. Please refer to the following table for
a complete description of the pin definitions.
