points
1. An Analog Power Supply Unit is counted as one Unit, the same as I/O Units
2. I/O points = Input points (256 max.) + Output points (256 max.)
When only a CPU Block is used, a maximum of 11 I/O Units and Dedicated I/
O Units can be connected to the CQM1H-series CPU Unit. When an Expan-
sion I/O Block is also used, a maximum of 5 I/O Units and Dedicated I/O Units
can be connected to the CQM1H-series CPU Unit and a maximum of 11 I/O
Units and Dedicated I/O Units can be connected to the Expansion I/O Block. If
these limits are exceeded, the CQM1H may not operate properly because of
drops in the voltage of the 5-V internal power supply. The CQM1H will detect if
the maximum number of I/O points has been exceeded (as explained below),
but will not detect if the maximum number of Units has been exceeded. There-
fore, design the system so that the maximum number of Units is not
exceeded.
When the maximum number of I/O points is exceeded, an “I/O UNIT OVER”
message will be displayed and operation will stop. For details on I/O UNIT
OVER errors, refer to the CQM1H Programming Manual .
The relationship between the maximum number of I/O points and Unit word
allocation is shown in the following table. The CPU Unit has 16 built-in inputs
for which one word is allocated.
