"EDIT" toggles the cursor between the top and bottom line.
"DELETE"
If the cursor is at the end of the equation it deletes the last item in the
equation, otherwise it deletes the item under the cursor.
"ACK"
saves the equation.
"NEXT" &
step through outputs (e.g. relays).
"PREV"
NOTES:
1. Operators NOT AND OR XOR have an associated precedence (or priority) as
described previously and are not necessarily evaluated left to right.
2.
It is recommended that parentheses be used liberally to ensure the correct order of
evaluation.
3.
It is recommended that all equations be written on forms before they are entered, and
checked against the forms after they have been entered.
Example
NOTE
this example has been taken from the F3200 programming manual. The RDU does
not have module relays or open collector outputs.
Enter an equation to program module relay 5 to activate if Zones 9 or 10 go into alarm, but
not if Open Collector 4 is active (say open collector 4 drives a status LED and has a logic
equation entered to do this).
The equation is:
R5 = (Z9A + Z10A).^OC4
From the "System Configuration" menu (4), select "Output Logic" (4) followed by "relay" (1).
Use "NEXT" to step onto Relay 5 (R5).
