- Participants should:• Know the advantages of the message system• Be able to adapt the message system to the requirements of their plant• Be able to configure messages• Be able to create message archives• Be able to archive messages
- GeneralThe message system enables events from the PLC or from the monitoring function in ProTool/Pro ( operating states, faults, etc.) to be displayed in the form of messages, allows them to be archived if required and printed out, and also enables them to be acknowledged by the operator.For this purpose you have to configure messages, which are divided into three different classes. 1) Event messages: These are used for indicating plant states. 2) Alarm messages: These are used for critical occurrences in the plant.They have a higher priority than the event messages and have to be acknowledged by the operator. 3) System messages: These are used by ProTool/Pro to display information about the system. The messages are also stored in a FIFO buffer or sequence archive on the hard disk to enable the user to refer to the history.
- Example: IntroductionThe display of an event message on the screen is triggered by the setting of a bit in the user program in the PLC. A message can be triggered by either a memory bit or a data bit. The message continues to be displayed as long as the bit remains set. DescriptionThe machine operator is about to start a filling operation, but has forgotten to open the water inlet valve on the mixer. The message "Open Water Inlet Valve" would immediately alert the operator to the error and enable it to be corrected as quickly as possible. Contact switchThe information as to whether the water inlet valve is open or not is provided by a contact switch at an input on the PLC, such as I 0.0. This information must then be evaluated in the user program. This can be done, for example, by performing a logic operation with this input (AN I 0.0) and a message bit (in this case M 41.0). Bit arrayA bit array consisting, for example, of memory or data words, indicates the current status of each message. Each bit that is set in the array (in this caseM 41.0) indicates that the relevant message is active. Area pointerThe system (OP or PC) independently reads in the bit array from the PLC. A so-called area pointer cyclically "scans" the bit array and recognizes whether a bit is set. If memory bit 41.0 is set in the array in our example, the associated message (in this case event message No. 1) is displayed on the screen. Message textYou enter the necessary message text and the "area pointer list" with ProTool/Pro. You use the area pointer list to assign the messages in the operating unit to the bits in the array on the PLC. In the example, memory word MW 40 is used for event messages 1 to 16.
- Exercise 1aConfiguring an area pointer Area pointer list- Add - Event Messages - DB127, DBW10 - Length 1. Screen / Keys- Activate the message indicator (This appears when and for as long as alarm messages are active) and select the window display mode for the event and alarm messages. Note:Arrange the positions of the message window and message indicator so that they do not obscure any important information on your screen.
- Exercise 1bMaking message settings for the destination system System-Messages / Settings Properties box: Message Settings-Printout ( without printer: "off" | with printer: "ON") -Alarm Messages -Buffer Overflow -Character / Titles
- Exercise 1cConfiguring message texts Message Editor- Select Event Messages. Configure event messages Nos. 1 to 16 with info texts. (You can also underline the messages or make them flash!).
- Exercise 1dCreate the message view shown on page 9 Buttons- Configure the buttons: - Functions/Messages/Show_event_message_buffer. - Functions/Messages/Show_event_message_window. - Functions/Messages/Show_event_message_page. Function keys- Configure the function keys: - Function key F1 / Keyboard / Other Functions / Display_Help_text. - Function key F3 / Keyboard / Go_to_Home - Function key F4 / Keyboard / Page_Up. - Function key F5 / Keyboard / Page_Down. - Function key F6 / Keyboard / Go_to_end. - Function key F10 / Messages / Clear_message_buffer. Screen Object- Set the Message View properties Properties box: General- Messages - Message Events - (S7) Diagnosis Buffer From PLC - Message Archive - Message Classes Columns- Visible Columns;-Sort;-Column Properties Display- Display;-Multi-Line Display; -Size To Fit Test- Open your message view. - Trigger event messages by making entries in the DB127 DBW10 input field.- You can enter a value for the variable in DB127, DBW0 and this value must appear in the display after the event message is triggered.- Click the buttons to view the event message window, event message buffer and event message page.
- Exercise 1eEvent messages General- This time the event messages are to be managed in the RAM of the PC and displayed on the monitor direct.- 1024 event and alarm messages can be handled in the RAM when it is used as a FIFO buffer. - 500 event messages and 250 alarm messages can be queued at the same time ( See also the ProTool/Pro Runtime User's Guide) - The next step is to configure an archive in which the messages are stored on the hard disk. Exercise 1fCreate the message screen (see above) - Configure a Simple Message View in the fixed window.- Message view in the main screen with buttons NoteAs of Version 6.0 you can also display messages that give the error location and a time stamp in milliseconds.
- Technical Specifications Archive typesShort-term archives, sequence archives Data that can be archivedProcess values, messages Max. archives/project40 Max. meas. points/project40 Max archive sizeDepends on amount of space free on hard disk Data storage formatCSV (Comma Separated Variable) Archiving message events• You can create a separate archive for each message class (event messages / alarm messages / system messages).• When message events are entered in the message buffer they are also entered in the archive. History trendsTrends that use an archive as data source. Archive evaluationYou can use external applications, such as MS Excel, to evaluate the archives of a ProTool/Pro system.
- Short-term archiveA short-term archive is a FIFO buffer that can contain up to n values. When the buffer is full, the old values are overwitten one after the other. Sequence archiveA sequence archive consists of a number of files.Data is written to the first file until it reaches a specified length. After that the next file is used. The switch is made either automatically or by user action.When the pre-arranged number of files have been filled, the first file is overwritten. Data storage formatCSV files- The contents are stored in a file as ANSI characters- Entries are separated by delimiters- CSV files can be read in and edited with standard tools such as Excel Storage media• Hard disk• Floppy disk• PCMCIA card• Flash/ SRAM Archive functions- Start archive- Stop archive- Delete archive- Unscheduled archiving of a value- Copy archive- Open archive- Close archive- Begin sequence archive- Archive tag Archiving process tags Trigger conditions- Cyclically, after every change, or when a tolerance range is exceeded Tolerance range- Definition of the upper and lower limits
- Exercise 2aCreating a message archive Archives- Insert Object. Properties box: General- Enter the Archive Name - Change the Data Source to Messages - Select the settings for Behavior on Restart Settings- Enter the Path Name (folder C:HMI) - Select the Size - Select the settings for Behavior When Archive Full NoteWhen you select this attribute (see above) the message text is archived in the current online language.
