2-14-2 CPM2A/CPM2C Quick-response Inputs

154
The CPM2A and CPM2C have four inputs used for quick-response inputs
(shared with interrupt inputs and 2-kHz high-speed counter inputs). With quick-
response inputs, signals that are changed within a cycle can be received by
maintaining an internal buffer.

00006 (See note 2.)
Note 1. Input numbers 00003 to 00006 can be used as interrupt inputs, 2-kHz high-
speed counter inputs, or quick-response inputs. If they are not used for any
of these purposes, then they can be used as ordinary inputs.
2. Input number 00006 does not exist in CPM2C CPU Units with 10 I/O points.
The following table shows the relationships between quick-response inputs and
the CPM2A/CPM2C's other functions.

Note 1. Quick-response inputs utilize the interrupt input function, so the same input
number from 00003 to 00006 cannot be assigned for both a quick-response
input and an interrupt input in the PC Setup.
2. A quick-response input and an interrupt in counter mode cannot be as-
signed the same input number in the PC Setup.
3. The input numbers allocated for quick-response inputs are 00003 to 00006.
These inputs can be set and operated as quick-response inputs.
4. Input time constants are disabled for all inputs that are set as quick-re-
sponse inputs.
