CQM1 Cycle Time and I/O Response Time Section 7-1
3. The slave executes communications servicing immediately after comple-
tion of communications.
The minimum I/O response time is as follows:
Input ON delay: 8 ms
Master cycle time: 10 ms
Transmission time: 39 ms
Slave cycle time: 15 ms
+ Output ON delay: 10 ms
Minimum I/O response time: 82 ms
Maximum I/O Response
Time
The CQM1 takes the longest to respond under the following circumstances:
1,2,3... 1. The CQM1 receives an input signal just after the input refresh phase of the
cycle.
2. The master to slave transmission does not begin on time.
3. Communications are completed just after the slave executes communica-
tions servicing.
