Read this chapter completely before you attempt to install or configure
your Communications Module. Double check all connections and option
selections before you apply power.
IMPORTANT: Switch selections take effect only on power-up. If
selections are changed after power is applied, cycle the power to use the
new settings.
Setting Module This publication describes switches as being either on or off. If the switch
Configuration Switches assembly has the word OPEN printed on it, the word OPEN corresponds to
OFF (0).
When making configuration changes to the 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 the target processor can recognize.
ATTENTION: When you make changes to 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 you 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, that the motor be disconnected from
the machine or process during initial testing.
