SRM1 Cycle Time and I/O Response Time Section 7-3
Minimum I/O Response
Time
Minimum I/O response time =
Input ON delay + Output ON delay + CompoBus/S communications cycle time
+ SRM1 cycle time
Maximum I/O Response
Time
Maximum I/O response time =
Input ON delay + Output ON delay + CompoBus/S communications cycle time
+ SRM1 cycle time x 2
7-3-4 One-to-one Link I/O Response Time
When two SRM1s are linked one-to-one, the I/O response time is the time
required for an input executed at one of the SRM1s to be output to the other
SRM1 by means of one-to-one link communications.
Minimum I/O Response
Time
The SRM1 responds most quickly under the following circumstances:
1,2,3... 1. The SRM1 receives an input signal just prior to the I/O refresh phase of the
cycle.
2. The Master’s communications servicing occurs just as the master-to-slave
transmission begins.
