Description
With the Pulse on pos. edge logic device, an ON pulse with adjustable pulse duration is created
if a monitoring or system device changes state from OFF to ON.
The state of the Pulse on pos. edge logic device is calculated according to the following table:
Configuration log
Linked device Result of the link
switched off (OFF) switched off (OFF)
switched on (ON) switched on (ON) for the length of time set under
pulse duration
other switched off (OFF)
Notice
While the ON pulse is present at the output, the input is not monitored, i.e. a change of the
input state during the ON pulse is not evaluated and has no effect on the ON pulse. The func-
tion of the device corresponds to a non-retriggering monoflop.
Notice
Even a short communication error on the AS-Interface line results in an ON pulse at the output!
Example:
0104 INDEX: 43 = "Name"
0105 TYPE: 44 = convert edge to pulse
0106 SUBTYPE: on positive edge
0107 ASSIGNED: channel one
0108 IN DEVICE: 36 = "AOPD1"
0109 PULSE WIDTH: 0.005 Sec
