TIP
Connecting the GuardPLC 1600
Connections for Safety-Related Communications
The controller has four 10/100BaseT, RJ-45 connectors to provide communications
via GuardPLC Ethernet to distributed I/O and other GuardPLC controllers, OLE for
Process Control (OPC) servers, and with the programming software. Connectors 1
and 2 are located on the bottom side on the left. Connectors 3 and 4 are located on
the top side on the left. All four connectors and the GuardPLC processor are
connected together by an internal Ethernet switch. The switches are auto-detect.
Either cross-over or straight-through Ethernet cabling can be used.
Star or line configurations are available. Make sure that a network loop is not
generated. Data packets must only be able to reach a node via a single path.
OPC Server
The GuardPLC 1600 is an OPC client. An OPC server, catalog number 1753-OPC, is
available from Rockwell Automation and allows PC applications to read and write
data to and from the GuardPLC.
MAC Address
The Media Access Control (MAC) Address of the controller can be found on the
label positioned over both lower RJ-45 connections.
Connections for Non-Safety-Related Communications
Three 9-pin D-shell connectors are located on the front of the controller, providing
the following communications:
