RS232 connections (CX50x0-N030)

The CX50x0-N030 system interface provides an RS232 interface, COM1 (X300). It is implemented on a 9-pole Sub-

D pin strip. If more than one interface is required the system can be extended via the Terminal Bus (K- or E-bus) or

Bus Terminals (KL/EL6001) which provide serial interfaces. The pin assignment is shown at the bottom of the page.

The maximum baud rate on both channels is 115 kbit. The interface parameters are set via the operating system or

from the PLC program.
