Function Blocks
Block Content
Resource Block The Resource Block contains all the data that uniquely
identifies the field instrument. It is an electronic version
of a nameplate of the instrument.
Analog Input The AI block takes the manufacturer's input data,
Block 1 selected by channel number, and makes it available to
Analog Input other function blocks at its output.
Block 2
PID Block The PID block serves as proportional-integral-derivative
controller and is used almost universally to do closed-
loop-control in the field including cascade and
feedforward.
Arithmetic Block This block is designed to permit simple use of popular
measurement math functions. The user does not have to
know how to write equations. The math algorithm is
selected by name, chosen by the user for the function to
be done.
Input Selector The input selector block provides selection of up to four
Block inputs and generates an output based on the configured
action. This block normally receives its inputs from AI
blocks. The block performs maximum, minimum, middle,
average and 'first good' signal selection.
Signal The signal characterizer block has two sections, each
Characterizer with an output that is a non-linear function of the
Block respective input. The non-linear function is determined
by a single look-up table with 21 arbitrary x-y pairs.
