Appendix 1 Operations of when the MC/MCR instructions are used to control EN
Retentive timer (low-speed timer/timer/high-speed timer), counter, and long counter
The following describes operations of the retentive timer (low-speed timer/timer/high-speed timer), counter, and long counter.
Ex.
A subroutine-type FB using a low-speed retentive timer
■When "Yes" is selected for "Use MC/MCR to Control EN"
The current count value remain unchanged. ((1) in the following figure). The coil turns off ((2) in the following figure).
■When "No" is selected for "Use MC/MCR to Control EN"
The current count value and the current state of the coil remain unchanged. ((1) in the following figure).
Sc: Scan
ST0 (Count): T0 (count value)
ST0 (Coil): T0 (coil)
 EN is turned off. (User operation)
 The coil turns off, but the current count value and the current state of the contact remain unchanged. (CPU module operation)
Sc: Scan
ST0 (Count): T0 (count value)
ST0 (Coil): T0 (coil)
 EN is turned off. (User operation)
 The values remain unchanged. (CPU module operation)
