5 Logic Functions (maximum of 10) - OR, AND, AND, NOT and ANY2.
8 Arguments (maximum of 20 per logic function) - L1D1,L1D4,L2D6,L2M3,L2M4....
The equation contains no spaces.
Evaluating an Equation
To evaluate an equation, start from the innermostpart of the equation and work outwards. For this
equation to evaluate TRUE and thus turn on any output mapped to it, the following conditions must
be met:
OR(AND(L1D1,L1D4),AND(L2D6,L2M3,NOT(L2M4)),ANY2(L1M13,L1M14,L1M15))
Trouble Equations
A trouble equation follows the same syntax rules as the logic equation. The system allows up to ten
trouble equations, ZT01 through ZT10 It differs from a logic equation in the following manner:
•Equations evaluate as true when the arguments go into trouble.
•Argument entries may consist of system trouble codes. Refer to Appendix H: System
Troubles for a listing of these codes.
Examples:
AND(L1M149,L2M110) will evaluate as true when both arguments go into trouble.
OR(T49,T50) will evaluate as true when either argument goes into trouble.
These have
to be ON These have
to be ON.......and this OFF Any TWO of these
have to be ON
for this part to be TRUE
for this part to be TRUE
for this part to be TRUE
When this is TRUE OR When this is TRUE OR When this is TRUE
Then all outputs programmed with this equation will be turned ON.
