)
Twenty-four input bits in two words are allocated (bits 00 to 11 in CIO m and
bits 00 to 11 CIO m+1). Sixteen output bits in two words are allocated (bits 00
to 07 in CIO n and bits 00 to 07 in CIO n+1).
Two input words (24 bits) and two output words (16 bits) are allocated to a 40-
point Expansion I/O Unit. Input bits 12 to 15 cannot be used as work bits. Out-
put bits 08 to 15, however, can be used as work bits.
4-2-3 I/O Allocation Examples with Expansion I/O Units
Example 1: Maximum I/O Capacity
The configuration shown in this example is for the maximum I/O capacity. It
consists of a CPU Unit with 40 I/O points and three Expansion I/O Units, each
with 40 I/O points. Up to three Expansion I/O Units can be connected to a
CPU Unit with either 30, 40 or 60 I/O points.
When Expansion I/O Units with 40 I/O points are connected, control is possi-
ble for up to 160 I/O points, including 96 inputs and 64 outputs.
