Elements of an Application Program
Retentive RESET Resets the associated discrete reference OFF if the coil receives
power. The reference remains reset until set by an –(SM)– coil.
Its state is retained through power failure and STOP-TO-RUN
transition.
Negated Sets the associated discrete reference ON if the coil does not
receive power. The state is retained through power failure and
Retentive
STOP-TO-RUN transition. Otherwise OFF.
Retentive Sets the associated discrete reference ON if the coil receives
power. The state is retained through power failure and STOP-
TO-RUN transition. Otherwise OFF.
Continuation If power to the coil is ON, the continuation coil sets the next
continuation contact ON. If power is OFF, the continuation coil
sets the next continuation contact OFF.
On-Delay Accumulates time while receiving power The current value is
Stopwatch reset to zero when the Reset input receives power.
Timer
Off-Delay Timer Accumulates time while NOT receiving power.
On-Delay Timer Accumulates time while receiving power The current value is
reset to zero when there is no power flow.
Up Counter Increments by 1 each time the function receives transitional
power.
Down Counter Counts down from a preset value every time the function receives
transitional power.
Addition Adds two numbers.
Subtraction Subtracts one number from another.
Multiplication Multiplies two numbers.
Division Divides one number by another, yielding a quotient.
Modulo Division Divides one number by another, yielding a remainder.
Power of X Raises X to the power specified by IN and places the result in Q.
Trigonometric Finds the trigonometric sine of a real number.
Sine
Trigonometric Finds the trigonometric cosine of a real number.
Cosine
Trigonometric Finds the trigonometric tangent of a real number.
Tangent
Inverse Sine Finds the inverse sine of a real number.
Inverse Cosine Finds the inverse cosine of a real number.
Inverse Tangent Finds the inverse tangent of a real number.
