SRM1(-V2) Cycle Time and I/O Response Time
8-3-1 The SRM1(-V2) Cycle
The overall flow of SRM1(-V2) operation is as shown in the following flowchart.

Note
1. The cycle time can be read using Programming Devices.
2. Cycle time maximum and current cycle time are stored in AR 14 and AR 15.
3. Change to processing will cause cycle times to change therefore the calcu-
lated values and actual values (for cycle time) will no always match.
