8 Connection and function of the programming port (PROG PORT)
The project data is loaded into the Touch Operator Panel (Download) via the programming port (PROG
PORT). The programming port can also be used to connect a serial printer for printing reports from the
application or for the communication via SUCOM-A protocol (from MV4-Configurator MV4-CFG-1, V 3.03).
Refer to the documentation of the MV4-configurator design software for information on
the connection and operation of a printer (printer installation).
For SUCOM-A communication select the PLC type “Moeller...PRG (COM)” in the MV4-configurator. The
required SUCOM-A cables ZB4-237-KB1 (for PS4) and ZB4-233-KB1 (for PS416) must be used with an
adapter (9-pol. SUB-D female connector to 9-pol. SUB-D female connector). This can be ordered under the
designation LT307.512.1.
The programming port is a standard RS 232 interface.
The GND terminal is located directly on the housing potential (see Section 17). Cables connected to the
PROG PORT must be laid separately to low-voltage cables.
Pin 9 can be provided with an optional +5 V (see Section 11).
