Quick Logic
The ‘Quick Logic’ feature allows the user to input up to 4 logic equations (E1 to E4) in text format. Equations can
be entered using Reydisp or at the relay fascia.
Each logic equation is built up from text representing control characters. Each can be up to 20 characters long.
Allowable characters are:
0, 1, 2, 3, 4, 5, 6, 7, 8, 9

E1= ((I1^F1).!O2)+L1
Equation 1 = ((Binary Input 1 XOR Function Key 1) AND NOT Binary Output 2)

LED 1
When the equation is satisfied (=1) it is routed through a pick-up timer (
En Pickup Delay
), a drop-off timer (
En
Dropoff Delay
), and a counter which instantaneously picks up and increments towards its target (
En Counter
Target
).
The counter will either maintain its count value
En Counter Reset Mode
=
OFF
, or reset after a time delay:
En Counter Reset Mode
=
Single Shot
: The
En Counter Reset Time
is started only when the counter
is first incremented (i.e. counter value = 1) and not for subsequent counter operations. Where
En
Counter Reset Time
elapses and the count value has not reached its target the count value is reset to
zero.
En Counter Reset Mode
=
Multi Shot
: The
En Counter Reset Time
is started each time the counter is
incremented. Where
En Counter Reset Time
elapses without further count increments the count value
is reset to zero.
