First registration generates this error.
Displayed when an I/O verification
error has already occurred.
The On-line Unit Change operation allows mounting and/or removal of I/O
Units while the CPU is operating. Only 16-, 32-, and 64-point I/O Units can be
changed on-line. On-line changes are not possible on Racks containing Inter-
rupt Input Units, Special I/O Units, or Remote I/O Units. Regardless of
whether or not the On-line Unit change operation is used, do not mount a
Remote I/O Unit or a Special I/O Unit to a C2000-BI083 Backplane. Doing so
will result in an I/O bus error.
Removal or mounting can be done in RUN, MONITOR, or PROGRAM mode.
The entire operation must be repeated for each Unit individually, using the
following procedure to attach Units.
Align the bottom of the I/O Unit on the hook on the Rack.
2. Pivoting the Unit on the hook, press in to insert the connector.
3. Tighten the screws at the bottom and top of the I/O Unit.
AR 22 is used to monitor the operation as follows:
