Details
When this command is set to on, the timer performs the delay operation.
When this command is set to off, there is no timer on the delay operation.
You must enable a timer before it can use the delay settings or the alarm configuration. For expected results
from the timer, it is best to disable the timer before changing a timer setting, such as delay or start seconds.
To use the timer as a simple delay or pulse generator with digital I/O lines, make sure the timer start time in
seconds and fractional seconds is configured for a time in the past. To use the timer as an alarm, configure the
timer start time in seconds and fractional seconds for the desired alarm time.
