Display Basics

The Display Interface Block (DIF) contains the list of all displays that can be shown on
the operator display. The State Table block (ST) contains a file with lists of numbers to
be translated into text on the displays. Because only one of these blocks is allowed per
controller, the Display Interface Block and State Table Blocks are placed in the strategy
automatically by the configuration software.
Tune List (TL) blocks are used to create displays that are accessed only when needed.
Typically they will include P,I,D tuning parameters and other commissioning information,
but they can also be used to create recipe selection pages and other displays that remain
hidden until needed.
Process Alarm Display (PAD) blocks are used to define alarms and how they will be
indicated and displayed. It is not necessary to use the Display Block to create alarm
indication. PAD blocks are usually connected to PID blocks, but can be used with any
algorithm block.
In general, the steps to creating a MOD 30ML display are:
1. create the Display Block corresponding to the algorithm block, and make the
appropriate connections;
2. enter each Display Tag in the Display List of the Display Interface Block;
3. Create State Tables in the State Table block to present text corresponding to
parameter codes on the front panel.
2.2 Using a smart symbol COMPOUND
The configuration software includes a gallery of pre-defined strategies known as
compounds. These include:
PID-100 – A complete PID loop with one built-in analog input, input function block, PID
block, analog output block, Display and Tuning
PID&ALM – A complete PID loop as in BASICPID, with the addition of a high and a
low process alarm with alarm display
PIDTOT1 – A complete PID loop as in BASICPID with the addition of a totalizer. A
single display is used for indication and operation of the PID loop and totalizer.
PIDTOT2 – This is the same as PIDTOT1, but with two separate displays for indication
and operation of the PID loop and totalizer.
PID_OPH – A compound for using and displaying the MOD 30 Output Holder with
MOD 30ML, including feedback signal. For more information refer to IB-MLAPP-OH.
CAS&DSP – A cascade loop with displays and tuning for both master and slave loops.
