Function
Makes settings common to all function blocks and
outputs signals for the system.
2-position type ON/OFF controller
3-position type ON/OFF controller for heating/cooling
ON/OFF control
Performs basic PID control.
Performs PID with two degrees of freedom control for
enabling deviation/MV compensation, MV tracking,
etc.
Performs PIF control on the cumulative value
(cumulative deviation) between the accumulated value
PV and accumulated value Remote Set Point.
Functions to open the valve at a fixed opening until a
fixed batch accumulated value is reached.
Inputs up to eight analog inputs and then outputs up
to two analog outputs based on fuzzy inferences.
Manual setter with PV indication and and SP setting
functions
Manual setter with PV indication and MV setting
functions
Ratio and bias setter with PV indication and ratio
setting function
PV indicator with PV alarm
Performs monitoring and setting for an ES100X
Controller connected directly to the RS-232C port on
the Loop Control Unit.
Provides the alarm contact outputs for the high/high,
high, low, and low/low limits of single analog signals.
This function block provides the same function as the
Indicator block (model 034).
low limits of single analog signals.
two analog signals.
Provides the alarm contact outputs for the high and
low limits of rate-of-change operation when the analog
signal rate-of-change is output.
Limits the high and low limits of single analog signals.
Calculates the deviation between two analog signals,
and limits the deviation within that range.
Holds the maximum, minimum or instantaneous value
of single analog signals.
Performs addition/subtraction with gain and bias on up
to 4 analog signals.
Performs multiplication with gain and bias on up to 2
analog signals.
Performs division with gain and bias on up to 2 analog
signals.
Performs various math operation (trigonometric.
logorithmic, etc.) on floating-point decimal values
converted (to industrial units) from up to 8 analog
inputs.
Converts analog ranges for up to eight analog signals
based only on values input for 0% and 100% inputs
and 0% and 100% outputs.
