The following figure shows the word allocation for a fully expanded C200H with
three 8-slot Backplanes.
There are limits to how long the normal wiring between the PC and its Expansion
I/O Racks can be. A Remote I/O Unit can extend this distance greatly, so that the
PC and its Expansion I/O Racks can even be located in separate buildings.
There are two types of Remote I/O Systems, optical and wired.
By locating a Rack farther from the CPU Rack, a Remote I/O System eliminates
the time and mess in wiring (or changing wiring) to many devices that are sepa-
rated from the CPU Rack. Although all I/O points must ultimately be wired indi-
vidually, the question is one of distance: Do you want to wire dozens of terminals
all the way across a factory complex or do you want to run a single cable for most
of the distance and then wire individual terminals locally? A PC with an Expan-
sion I/O System is called an Expanded PC.
I/O words 100 through 199 and DM words 1000 through 1999 are allocated to
Special I/O Units. There are limitations to the number and model of Special I/O
Units that can be mounted to a Remote I/O Slave Rack. Provided no other mod-
els of Special I/O Units are mounted to a Remote I/O Slave Rack, the maximum
number of Special I/O Units that can be mounted is shown below for each model.
When using a combination of A, B, C, and D Units on a Remote I/O Slave Rack,
the number of each model of Unit being used must satisfy the following two for-
mulas.
