Mounting Units to the Backplane
38
there is still some space available on the left side of the Backplane. This space is
for any additional I/O Units that may be required.
The figure above shows a total of eight I/O Units mounted to the Backplane.
When using 16-point Output Units (models C200H-OC225/OD212/OD21A)
mount them to a C200H-BCjj1-V1/V2 Backplane. If a Backplane other than
this model is used, the Units will not operate properly.
Interrupt Input Units must be mounted to a C200H-BCjj1-V2 Backplane to op-
erate properly. Only one Interrupt Input Unit can be mounted per PC.
Backplanes are available in different lengths (three, five, eight, ten slots), and
can hold a different number of I/O Units accordingly (refer to Appendix B Specifi-
cations for dimensions). Of course, not all I/O Units look exactly alike, but the
ones in the figure show their typical appearance. This configuration of Back-
plane, CPU, and I/O Units is called a CPU Rack. This term refers to the Back-
plane and all the Units mounted to it. However, if we want to include more than
eight I/O Units in our configuration we can add an additional Backplane.
This Backplane has I/O Units mounted to it, but it has no CPU of its own. The
additional Backplane must also have an Expansion I/O Power Supply mounted
to its rightmost position. This configuration of additional Backplane, Expansion
I/O Power Supply, and I/O Units is called an Expansion I/O Rack.
The CPU Rack and Expansion I/O Rack shown above are connected by a Con-
necting Cable (the length of Cable between individual Racks can be up to 10 m,
but the total length of Cable between all Racks must be within 12 m).
Remember that this whole configuration is still referred to as one PC. It is possi-
ble to add up to two Expansion I/O Racks and five Remote I/O Slave Racks to
one CPU Rack. When installing I/O Connecting Cables, cover any unused con-
nectors with the caps provided.
