You can place your module in any I/O module slot of the I/O chassis
with the following guidelines:
•
Do not put the module in the same module group as a discrete
high-density module.
•
Avoid placing output modules close to ac modules or
high-voltage dc modules.
•
Group output modules together within an I/O chassis whenever
possible to minimize noise interference from other modules.
•
You can put two output modules in the same module group.
The module configuration jumpers consist of:
•
the last state configuration jumper (all versions)
•
the voltage range configuration jumpers (1771-OFE1 only).
Current Output Version
Current version modules (1771-OFE2 and -OFE3) have all
configuration jumpers installed and require no additional
configuration. The configuration jumper for the Last State mode
output level is in the default position (MID). See “Last State
Configuration Jumpers” below.
Voltage Output Version
If you are using the voltage output version, you need to set several
configuration jumpers on the module’s circuit board. You must set
these jumpers before you can proceed with configuring the module.
When you set these jumpers, you configure each channel for one of
the three voltage ranges listed above. The module is shipped with
the plugs in the +10V position.
Important: You do not have to remove the module cover to set the
configuration jumpers
Last State Configuration Jumpers
The LAST STATE configuration jumpers determine the value of all
the module’s outputs whenever communication between the module
and the processor is lost. This condition occurs when a processor or
adapter faults, or the processor is placed in the PROG or TEST
mode, or if the remote I/O cable breaks.
