DESCRIPTION
This section describes the mechanical and electrical characteristics of
the Remote I/O module, Remote I/O Head, Remote Drive Interface
Head, and the Shark Interface module.
2.1 Mechanical Description
This section describes the faceplates, connectors, indicators, and
switches of the Remote I/O module, Remote I/O Head, Remote Drive
Interface Head, and the Shark Interface module.
2.1.1 Remote I/O Module (M/N 57C416)
TheRemoteI/O moduleis a printed circuit assembly that plugs into
thebackplaneof theDCS 5000/AutoMax Rack. Themoduleconsists
of a printed circuit board, faceplate, and protective enclosure. The
faceplate contains ejector tabs at the top and bottom to simplify
removing themodulefrom therack. Seefigure2.1 for an illustration
of themodulefaceplate.
The 25Ćpin DĆshell connector on the faceplate supports the RSĆ232
compatible serial port described in section 5.0. The 9Ćpin DĆshell
connector on the faceplate is used to connect the module to the
network.
The two thumbwheel switches on the faceplate are used to set the
remote I/O network drop number. The upper thumbwheel switch
represents the most significant digit; the lower thumbwheel switch
represents the least significant digit. The thumbwheel switches are
read only on powerĆup. If it is necessary to change the drop number,
you must changethesetting and then cyclepower. On theback of
themodulearetwo edgeconnectors that attach to thesystem
backplane.
For diagnostic purposes, the faceplate contains a sevenĆsegment
LED that displays error codes. The error codes are defined in
Appendix D. A green status LED on the faceplate indicates when the
module is operational (ON) or should be replaced (OFF).
