Timer Mode 5 (FLASH without reset)
Mode 5 Timer is a Flash timer without reset that will time up to a fixed preset value and then change the state of
its status bit. Additionally, the Timer current value will reset to zero when Timer is disabled. In the example below,
timer status bit T01 will be ON immediately when its rung is true and begin its timing sequence. Timer status bit T01
will turn OFF when the current time value reaches its preset of 10 seconds. This Flash sequence of the Timer status
bit T01 will continue as long as its rung remains true.
※
The current value of Timer can not be kept on a loss of power to smart.
