Execute output pulse

If the pulse is set to be adaptive, it is not possible for the pulse to exceed

tOpenPulse or tClosePulse.

The execute output pulses are reset when:

the new expected final position is reached and the configuration parameter

AdaptivePulse is set to true

the timer tOpenPulse or tClosePulse has elapsed

an error occurs due to the switch does not start moving, that is, tStartMove has

If the controlled primary device reaches the final position before the

execution pulse time has elapsed, and AdaptivePulse is not true, the

function waits for the end of the execution pulse before telling the

activating function that the command is completed.

There is one exception from the first item above. If the primary device is in open

position and an open command is executed or if the primary device is in close

position and a close command is executed. In these cases, with the additional

condition that the configuration parameter AdaptivePulse is true, the execute output

pulse is always activated and resets when tStartMove has elapsed. If the

configuration parameter AdaptivePulse is set to false the execution output remains

active until the pulse duration timer has elapsed.

If the start position indicates bad state (OPENPOS=1 and

CLOSEPOS =1) when a command is executed the execute output

pulse resets only when timer tOpenPulse or tClosePulse has

An example when a primary device is open and an open command is executed is

shown in Figure 107.
