GuardPLC 2000 System
The GuardPLC 2000 controller is a modular system consisting of a
controller (1755-L1), which provides central CPU and communication
functions, and a separate power supply and I/O residing in a
GuardPLC 1755-A6 chassis. A maximum of six I/O modules may be
used in a single system.
The GuardPLC 2000 controller has one active RS-232 serial port for
non-safety related communication. It also features an Ethernet port for
configuration and safety-related communication. The lower DB9 port
supports RS-232 ASCII (read-only) communication; the upper port is
inactive.
