Resource Block

This block contains all the data that uniquely identifies the device; it is

an electronic version of a nameplate for the device.

Analog Input

Block 1

Analog Input

Block 2

The AI Block receives the measuring data from the Sensor Block,

(selectable via a channel number) and makes the data available to

other function blocks at its output. Enhancement: Digital outputs for

process alarms, fail safe mode

Digital Input

Block

This block contains the discrete data of the Diagnose Block (selectable

via a channel number 0 to 16) and provides them for other blocks at

the output.

Digital Output

Block

This block converts the discrete input and thus initiates an action

(selectable via a channel number) in the DP Flow Block or in the

Service Block. Channel 1 resets the counter for max. pressure

transgressions.

PID Block

This block is used as a proportional-integral-derivative controller and

can be used universally for closed-loop-control in the field. It enables

cascade mode and feedforward control. Input IN can be indicated on

the display. The selection is performed in the Display Block

(DISPLAY_MAIN_LINE_CONTENT).

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 performed.

Input Selector

Block

The Input Selector Block facilitates the selection of up to four inputs

and generates an output based on the configured action. This block

normally receives its inputs from AI Blocks. The block performs

maximum, minimum, average and ‘first good’ signal selection. Inputs

IN1 to IN4 can be indicated on the display. The selection is performed

in the Display Block (DISPLAY_MAIN_LINE_CONTENT).

Signal

Characterizer

Block

The Signal Characterizer Block has two sections, each with an output

that is a non-linear function of the respective input. The non-linear

function is generated by a single look-up table with 21 arbitrary x-y

pairs.

Integrator Block The Integrator Block integrates a variable as a function of the time or

accumulates the counts from a Pulse Input Block. The block can be

used as a totalizer that counts up until a reset, or as a batch totalizer

whereby the integrated value is compared against a target value

generated before or during the control routine and generates a binary

signal when the target value is reached.

Analog Alarm

Block

This block contains all process alarm conditions (working like a

comparator) and represents them at the output.
