CBE (Control-By-Event)
Equation Entry
Example: AND(RANGE(Z1,Z20))
Zone 1 through Zone 20 must all be in alarm for the output point to be activated.
D.4.2 Equation Syntax Example
OR(AND(L1D1,L1D4),AND(L2D6,L2M3,NOT(L2M4)),ANY2(L1M13,L1M14,L1M15))
Equation begins with a logic or time delay function - OR
67 Characters
(maximum of 73) - includes parentheses and commas.
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.
D.4.3 Evaluating an Equation
When you evaluate an equation, you start from the innermost part 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))
D.4.4 Argument Entries
The argument entries of the logic functions can be another logic function or any of the devices
listed below:
Equations must be evaluated before use in another equation.
These must
be ON
These have
to be ON.........and this OFF
Any TWO of these
must 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.
