F183_DSTM

Timer 32-bit

The F183 instruction activates an upward counting 32-bit timer which works on-delayed. The smallest counting unit is 0.01s. During execution of F183 (start = TRUE), elapsing time is added to the elapsed value d. The timer output will be enabled when the elapsed value d equals the set value s. If the start condition EN is set to FALSE, execution will be interrupted and the elapsed value d will be reset to zero. The set value s can be changed during execution of F183.

Parameters

Input

s (DWORD, DINT, UDINT, DATE, TOD, DT): set value, range 0 to 2147483647

Output

d (DWORD, DINT, UDINT, DATE, TOD, DT): elapsed value, range 0 to 2147483647

Remarks

The delay time of the timer can be calculated using the following formula: (Set Value s) * (0.01s) = on-delay
