Explanations:
1. When the RST instruction is driven, the actions of the designated devices are:
Device
Status
Y, M, S,
Coil and contact will be set to “Off”
T, C
Present values of the timer or counter will be set to “0”, and the coil and contact will be set to
“Off”
D, E, F
The content will be set to “0”.
2. If RST instruction is not being executed, the status of the designated device will stay intact.

Explanations:
When TMR instruction is executed, the designated coil of the timer will be On and the timer will start to time. When the
set value in the timer is reached (present
≥
set value), the contact will be:
