Some functions relating to machine diagnostics can also be executed on the Operator Panel. If, for example, text for display is required to comprise static and variable components, the tags have to be configured and the static text for explaining the tags has to be entered - for example Page Visualizing And Controlling Processes Visualizing and controlling processes Display and The basic functions of an OP consist in displaying process states and in con- control functions trolling the process.

The following display and control functions can be con- figured on Operator Panels OP7 and OP screens event messages alarm messages Page 16 Alarm messages Alarm messages show, in contrast to event messages, critical machine states dur ing production operations.

Due to their urgency, they have to be acknowl- edged before any other action is possible. Alarm messages may contain process values. Process values are displayed either numerically - for example Motor speed or symbolically - for example Page 17 Multilinguality Message text, screens, help text and system messages may be displayed in several languages.

Up to three of the languages listed below can be loaded simultaneously on the same OP and presented to the operator for selection on line: German English French The coloring of the front foil conforms with machinery directive EN Display of up to 4 lines each having a maximum length of 20 characters; the height of the characters is 8 mm. Function keyboard 8 keys F1 to F4 and K1 to K4 for calling freely programmable, generally valid standard functions. The following displays can be configured: 4 lines each of 20 characters; height of characters is 11 mm 8 lines each of 40 characters; height of characters is 6 mm.

Function keyboard 24 keys F1 to F8 and K1 to K16 for calling freely configurable functions. The values quo- ted are the maximum values that can be managed by the OP. The keyboard of the OPs consists of two functional blocks: System keys Numeric keypad and control keys Function keys figure shows the keyboard of the OP7, by way of an example. Function keys Numeric Page System Keys 3. Examples of such actions include: Opening a screen Starting a screen printout Print Screen The following keys can be assigned global functions Page 32 Function Purpose Escape The ESC key has the following functions: Cancel Cancel field inputs provided that they ENTER have not been terminated by pressing Branch backward Within a screen, you branch back to the configured cross-jump destination by default, the last position called and, finally, from the start screen to the message level.

Page 33 The table below shows key combinations that can be used to activate func- combinations tions from the OP. Keys Function Purpose Adjust contrast Adjusting the contrast of the display. To do this, proceed as follows: Step Procedure Branch, as described in section 4. Using the arrow keys, select the input field you require within the screen entry. Page Entering Numerical Values 3. If the field already contains a value, this entire value is deleted from the field as soon as you enter the first new char- acter.

Page Entering Alphanumeric Values 3. If digits and letters the field already contains a value, this entire value is deleted from the field as soon as you enter the first new character. Once you have begun entering a value, you can no longer quit this field until you have confirmed or aborted your input.

Page 38 Incorrect Remedy Using keys input Character too With the keypad set to the numerical many key assignment, delete the character at the cursor position. The gap that ari- ses is closed through the characters being moved from right to left. Page Entering Symbolic Values 3. If a value field has to be filled by entering symbolic values, take the value from a list of options. Page Entering Timer Values 3.

If the field already contains a value, this entire value is deleted from the field as soon as you enter the first new character. Once you have begun entering a value, you can no longer quit this field until you have confirmed or canceled your input.

Page 41 Entering a A timer can be assigned a start value by means of an input field. These val- timer value ues must be entered in a specific manner depending on the PLC being used. The OP is in Download mode un- til a configuration is loaded.

Page 44 Changing The operating level is changed either by the operator or automatically by the operating levels OP figure Change by the operator: Press key to change the operating level from message level to screen level, ENTER to change the operating level from screen level to message level. You cannot branch backward from the message level by pressing ESC.

Process-specific imple- mentations, such as event messages or screens for the process, are not inclu- ded. At this point you screen level can control and monitor the process by means of suitable screens and stan- dard screens and perform system settings.

With reference to the standard screens, a description is provided below of the procedure for branching between individual screens within the screen hierar- chy. Page Screens Screens Displaying and On the OP, the process — for example, a processing machine or a mixing unit influencing the — is displayed on screens and manipulated.

The screens are configured by the process on configurer for specific users. Every screen may contain up to 99 entries. Irre- screen entry spective of the configured number of lines, precisely one entry is displayed per display page on the OP. Lines which may have not been fully configured are displayed as blank lines. Before selecting screens this is possible, they have to be selected.

A screen can readily be selected by means of soft key, function key, directory, PLC job. To edit a screen, proceed as follows: Step Procedure Select the screen you wish to edit as described in section 5. The cursor jumps to the first input field. Page 54 Supervisor The supervisor password is specified during configuration.

This setting can be changed on the OP. Format The password must be a minimum of 3 and a maximum of 8 characters long. It can be made up of digits and the characters A to F. In this case, the OP automatically prompts you to enter a password. Logging in via Step Procedure Page Password Management Password Management Functions The standard screen Password processing contains the following functions for managing the passwords: viewing the password list configuring passwords and assigning password levels deleting passwords changing passwords and password levels.

These functions can only be called in password level 9. For this purpose, log in beforehand using the supervisor password via Password processing Login. Page 57 pppppppp pppppppp pppppppp pppppppp Password level Password Password index Figure Password List Example: 4 x 20 representation Password index The passwords are numbered consecutively with a two-digit password index.

If no password is entered under a password index, the fields for the password and for password level are contain dashes. Page 58 Deleting a Step Procedure Result password Select the line in the password The cursor is positioned on the list, that contains the password first character of the field in entry to be deleted.

Overwrite the first character of The cursor jumps back to the the password with a zero and A message consists of at least static text and can also include tags.

The following types of message are displayed on the OP: event messages, alarm messages and system messages. Event and alarm mes- sages are initiated by the PLC. Due to their critical nature, alarm messages have to be acknowledged. Page 61 Standby message A sub-category of the event message is the standby message. The standby message is the event message number 0. It appears on the display when the OP is operating at the message level and event or alarm messages are not waiting.

Page Alarm Messages Message bit If there is a condition present in the current process for a message to be procedure issued — for example, a tag has been reached — a bit is set by the PLC ap- plication program in the data area for event and alarm messages.

The OP reads the data area after a configured polling time. After that, this message will not be displayed until the next time the OP starts up. Inhibited alarm messages are no longer inserted into the alarm buffer from the time of inhibition, either.

Page System Messages 7. For example, they draw your attention to maloperations or a breakdown in communication. This message type has top display priority. If a relevant fault occurs on the OP, the active event message or alarm message is removed from the display and a system message is issued in its place. Page Displaying Messages Displaying Messages Display Event and alarm messages are always output to the display at message level and are displayed according to display and message priorities.

If several messages having identical display and message priorities exist si- multaneously, the most recent is displayed in all cases, for both event and alarm messages. Page Display Sequences 7. Single message With this display sequence, only one alarm message, event message or display setting system message is shown on the display.

The message buffers can be called to view message history by means of standard screens.
