Installation
In this chapter, you will learn how to:
•
set the module configuration switches
•
mount the Serial Communications Module
•
connect the cables
•
connect the SCANport link
•
connect the power supply
Read this chapter completely before you attempt to install or
configure your Serial Communications Module. Double check all
connections and option selections before you apply power.
Important: Switch selections take effect only on power–up. If you
change selections after power is applied, cycle the
power to use the new settings.
When making configuration changes to the Serial Communications
Module, use the addressing conventions of the PLC/SLC processor
or serial device through which you are communicating. In all cases,
each serial device must have a unique address that the target
processor can recognize.
!
ATTENTION: When changing the switch settings,
use a blunt, pointed instrument such as a ball point pen.
Do not use a pencil because the lead (graphite) of the
pencil may damage the switch assembly.
!
ATTENTION: Failure to check connections and
switch settings for compatibility with your application
when configuring the communications module could
result in personal injury and/or equipment damage due
to unintended or undesirable operation.
!
ATTENTION: It is recommended that when a system
is configured for the first time, you should disconnect
the motor from the machine or process during the
initial testing.
This publication describes switches as being either on or off. If the
switch assembly has the word OPEN printed on it, the word OPEN
corresponds to OFF (0).
If a switch is shown as gray, then that switch does not affect the
function being covered.
