Caution
I/O Unit
Special I/O Units, such as the A/D Conversion Input Unit or the High-speed
Counter Unit, cannot be removed or mounted during operation. In addition, if
Special I/O Units and standard I/O Units are mounted on the same Rack, none of
the Units on that Rack can be removed or mounted without affecting the other
Units. However, there are combinations with other I/O Units that allow substitu-
tion during PC operation. The following table explains the instances in which
standard I/O Units, when used in combination with other I/O Units, can be
removed or mounted during PC operation. The groups defined in the table are
used only in this section and do not apply to groups of similar nature in other
manuals.
When removing or mounting an I/O Unit while the CPU is operating, be sure to
remove the terminal block from the I/O Unit first and then remove the I/O Unit
from the Backplane. If the entire I/O Unit is removed from the Backplane, output
signals are not cleanly disconnected, but may be sent to external devices, caus-
ing a sudden pulse to go the external device. This may in turn cause the device to
shudder. Also, when remounting the I/O Unit to the Backplane, fir st mount the
I/O unit and then the terminal Block to the I/O Unit.
I/O Units come in 5 shapes; A-shape, B-shape, C-shape, D-shape, and
E-shape. Refer to Appendix B Specifications for the dimensions of each Unit.
When only Units from Group A are mounted to a Backplane the I/O Units can
be removed or mounted during PC operation.
When Units from Group B are mounted on the same Backplane as Units from
Group A, only the Units from Group A can be removed or mounted during PC
operation. However, this does not apply when using 3G2C5-BI083.
When Units from Group C are mounted on the same Backplane as Units from
Group A, neither Group a Units nor Group C Units can be removed or
mounted during PC operation.
