These function blocks are as follows:
This function type: Is:
ABS An absolute value function block whose output is the positive value.
BIN2DEC A binary to decimal function block that takes sixteen input words and
produces one decimal output word.
COMPHYST A compare with hysteresis function block that checks for input equals preset
value with a hysteresis around the value.
DEC2BIN A decimal to binary function block that takes one decimal input word and
produces sixteen binary output words.
DELAY A time delay function block that echoes a logic input after a delay.
DERIV A derivative function block that calculates the change in input per second.
DIVIDE A divide function block that divides two signed integers.
EXOR2 An exclusive OR function that takes two inputs and provides two output
values, the XOR of those values and the NOT of the output value.
FILTER A first order low pass algorithm filter, with a programmable bandwidth in
tenths of radians per second.
4AND An AND function that takes four inputs and performs a logical AND.
4OR An OR function that takes the logical OR of four inputs.
FUNCTION A function that takes a user approximation for a function and linearly
interpolates between two of five possible points.
INTEGRATOR An integrator function block that does trapezoidal integration.
LIMIT A limiter function block that limits an input to programmed minimum and
maximum values.
LNOT A logical NOT function.
MINMAX A minimum or maximum function block that you can program to take the
minimum or maximum of two input values.
MONOSTABLE A one shot monostable function block that elongates a rising edge signal for a
specified time duration.
MULTIPLEXER A select function block that multiplexes one of four inputs based on the state
of the selector inputs.
MULTIPLY A multiply function block that multiplies two signed integers.
NO-OP A PLC space holder.
PI CTRL A proportional/integral control function block that takes the difference
between two inputs and performs a PI control with a proportional and
integral gains.
PULSE CNTR A pulse counter function block that counts rising edges of an input value.
RATE LIMITER A ramp function block that limits the rate of change of an input value.
SCALE A scale function block that uses the following formula: IN1

(MULTI/DIV).
SR FF A set-reset flip-flop.
SUB A subtract function block that subtracts two signed numbers.
T-FF A toggle flip flop function block that changes the state of the input.
2ADD An add function block that adds two signed numbers.
UP/DWN CNTR An up/down counter function block that increments or decrements to a
specified value in a specified amount of time.
