Release 05/99

Product Description

The

implementation of Operator Panels OP27 and OP37 enables operating
statuses, current process values and faults in respect of a connected PLC to be
graphically represented and the machine or system to be monitored easily oper

-

ated. In order to do this, the OPs are equipped with a lar

ge number of standard
functions. The method of display and operation of the OPs can be customized
using the ProT

ool configuration software to achieve optimum results in respect

of process requirements.
The OPs can be used to



control and monitor the process by means of the menu system. In this way

,
setpoints can be entered, for example, in the form of value input or pressing
configured function keys or to control positioning elements;



display processes, machines and systems on full–graphic and semi–graphic
screens;



visualize event messages, alarm messages and process variables, such as
output fields, bar graphs, trends or status display;



intervene directly in the process by means of the integrated keyboard.

The OPs are installation units for use directly at the machine location. The
degree of protection is high (front panel IP65), so the devices are suitable for
use in hostile industrial environments.

Installation locations for the units may be as follows:

OP27 OP37

Panels/Consoles Panels/Consoles

–

19” panels/racks

Before commissioning the OPs, they must be prepared for the task of visualiz

-

ing data from the PLC. T

o do this, data areas must be created in the PLC’

s

memory in the configuration; the data areas are used by the OP to communi

-

cate with the PLC.

Graphics

and texts to be displayed on the OP must be created beforehand using
a configuration computer (PC or PU) implementing the configuration software
ProT

ool. Before downloading the configuration data to the OP

, connect the

configuration computer to the OP (refer to the configuration phase in Fig

-

ure 1-1).
Once the configuration has been successfully downloaded, disconnect the con

-

figuration computer and then connect the OP to the PLC. The OP now commu

-

nicates with the PLC and reacts to program execution on the PLC in accor

­dance with the configured requirements (refer to the process control phase in
Figure 1-1).

Figure 1-1 outlines the configuration and process control phase.

1.1 Visualizing and Controlling Processes

The

basic functions of the OP27 und OP37 Operator Panels are the visualiza

­tion of process statuses and the operation of processes. The following display
and operating functions can be configured:

 screens


input/output of process values



bar graphs and trends



text or graphics lists

 messages
 logging
 print
 text


help text

 recipes


multiple languages



password protection



functions for function keys and soft keys.

Logically related process data from the PLC can be compiled, displayed on a
screen and individual parts of it modified. Screens may contain soft keys,
graphics, texts and values.

The OPs can display machines and systems as

full–graphics scr

eens

. This

makes it easier for the operator to find his way around.

Numeric, alphanumeric or symbolic values can be entered in input fields on the
OP which are then transferred to the PLC. Current values of the PLC are dis

­played in output fields in alphanumeric form.

Current process values can be output as numeric values, symbolic text,
symbolic graphs or in the form of bar graphs and trend curves.



Bar graphs

represent a value as a rectangular area. Bar graphs can be used to display
fill levels or quantities, for example.

 Trends

display a value continuously. This display mode is useful when displaying
values that vary with time, variations in temperature or pressure, for exam

-

ple.

V

arious graphic elements (bitmaps) or texts can be called into the display

depending on the process status. In this way

, for example, the current setting of
a valve can be visualized on the OP screen by means of symbolic graphics, or
text can be modified according to the situation.

Release 05/99

Messages

are displayed on the OP in plain text. The message text may also
contain current process values. Incoming messages are stored in a message
buf

fer together with their date and time.



Event messages

provide information and operating notes on current processes or machine
states, for example
Motor running at 3000 revs.

 Alarm

messages

provide information on critical machine states, for example
Motor speed too high.

Alarm

messages must be acknowledged on account of their ur

gency.

Messages are classified as event messages or alarm messages during configura

-

tion.

All message events can be additionally recorded by being printed out in online
mode on a connected printer

. Messages which have accumulated in the event

and alarm buf

fers can also be printed out.

It is possible to print the current status of a screen by pressing

PRINT SCREEN. It

is possible to configure a function which enables up to 20 screens to be printed
simultaneously.

T

exts identify individual parts of the screen in order to be able to assign the

fields displayed to the process.

Help texts represent additional information and notes for the operator which
can be configured in respect of the screens, input fields and messages. The help
text relating to an alarm message may display information on the cause of a
malfunction and how to clear it.

Complete machine data records can be stored as recipes in the OP

. A recipe
defines the data structure in a configuration. Data is assigned to the configured
structure on the OP

.

The purpose of recipes is to transfer several items of data collectively to the
PLC. In this respect, it is immaterial whether actual recipes, specifications of
quantities, distances to be traversed or temperature variations are involved.

Message texts, texts in screens, help texts and system messages can be stored
in three languages simultaneously in the OP and selected online.

The password protection feature prevents unauthorized operation of the OP

.

Dif

ferent passwords can be assigned to dif

ferent users or user groups, thus
authorizing or prohibiting access to specific control functions by assigning
dif

ferent password levels.

The

OPs are equipped with a range of function keys which can be assigned

operating functions, such as message logging on/of

f, screen selection and print
screen during configuration. The function keys may be assigned globally or
locally

. Globally means that the assignment applies to the whole configuration.
Locally means that the assignment applies only to a single screen. A function
key whose assignment changes from one screen entry to another is known as a
soft key

.

It

is possible to observe the operating status of the machine or system being
monitored using the OP screen and directly intervene in the process running
via the OP keyboard.

A screen occupies the entire display

The

fixed window can be used to display important process magnitudes or date

and time, since the contents are not af

fected by the screen currently open.

The main area comprises the entire display. It is superimposed by all other
areas (fixed window

, message window etc.). The main area contains the current

contents of the screen that is currently open.

Icons are used as symbols of specific screen functions. Icons are located above
or next to soft key function keys in order to describe the functionality of the
