FB_ALY_Timer_1Ch
The Timer 1Ch starts a timer which can be configured by timer mode and interval. According to the specific timer mode the timer is started, if the configured condition becomes TRUE (TON, TP) or the condition becomes FALSE (TOF).

bNewResult | BOOL | When a new result has been calculated, the output is |
bConfigured | BOOL | Displays |
bOut | BOOL | Output value affected by the configured timer. |
fbTimeElapsed | FB_ALY_Timespan | Elapsed time. |
