1. Configuring and Downloading ALARM_S Messages It is therefore important that the shared database is always up to date during the compilation process and that data synchronization is active see Shared Database with STEP 7 Chapter 6 1 2 ProAgent User s Manual Issue 12 99 7 13 Message Processing 7 5 7 14 Use of Resources ALARM_S messages are configured in STEP 7 The data is then stored in a shared database imported during the process of compiling the ProTool project and finally downloaded to the operating unit That means that ALARM_S messages use up resources on the operating unit The shorter the messages are the less storage space they will require A maximum of 2000 event messages and 2000 alarm messages can be created It is of no consequence in this regard which message procedure is used More detailed instructions can be found in the Appendix Chapter B 1 The appendix contains information about the memory requirement of configurations in the basis of which you can assess whether or not the memory of your operating unit is large enough for the intended configuration Note In STEP 7 there are restrictions regarding the number and size of tags that can be used within a message For more precise details please consult your STEP 7 documentation ProAgent User s Manual Issue 12 99 7 6 Message Processing Communicat

3. Operating unit Stages Involved in Configuring the Process Diagnosis ProAgent User s Manual 3 6 Issue 12 99 Introduction Programming the PLC Depending on the programming language you are using for the PLC the preparations for the process diagnosis will differ as follows e f you are using S7 GRAPH your programs will automatically be capable of diagnosis e f you are programming in LAD CSF STL you need the S7 PDIAG option package S7 PDIAG creates additional blocks for monitoring your process for the purposes of fault detection This is mostly done automatically Thanks to the global nature of S7 process diagnosis you can also work with different programming languages within the same system entirely as circumstances demand You can also detect and locate process faults in mixed sequential and logic control systems Programming the PLC and defining the settings in S7 PDIAG are the first steps in creating the process diagnosis That is followed by configuration of the operating units using ProTool and ProAgent Common Database as Interface When translating the PLC program the STEP 7 option packages store all the data required for the process diagnosis in a shared database ProTool then accesses that database when the operating unit is configured during the next stage Configuring the operating unit Once the STEP 7 program has been created the process di
4. A CPU 315 can process a maximum of 50 simultaneously pending messages Accordingly an operating unit can handle a maximum of four CPU 315s sending ALARM_S messages without overflow problems occurring Updating Since the CPU stores the message information when a fault occurs individual network stations e g an OP can log on at a later date and obtain an update However the CPU only stores information about pending messages Once all events arrival departure acknowledgement have occurred the message is deleted from the CPU When obtaining an update therefore the operating unit processes any missing events automatically if a message is not known to the PLC but the arrival and acknowledgement events are not entered on the operating unit The events are not entered in the message buffer in that case however Events processed in this way are identified on the operating unit by displaying the message status symbols in inverse type thus 1234567 A Kf HH MM SS DD MM YYYY GRUOO Boiler 13 temperature 190 degrees Inform shift supervisor Tel 007 Automatically Processed Events ProAgent User s Manual Issue 12 99 7 19 Message Processing 7 11 Buffer Overflow Message Archive All message events for event and alarm messages are automatically stored ina message archive The message archive can hold up to 512 message events Overflow Warning When the remaining buffer capacity specif

7. Message Processing Advantages of ALARM_S As compared with the message bit procedure ALARM_S has the following advantages e ALARM S is an active message procedure When a message is issued the CPU actively notifies all networked units The operating unit is relieved of the task of continually polling the message area e The process data always precisely reflects the situation at the time of the message This can not be guaranteed with the message bit procedure The time stamp precisely indicates when an event occurred even if the operating unit is not connected until a later time Display Classes Priorities 7 2 The individual messages can be assigned different display classes in STEP 7 When configuring in ProTool you then can then choose a specific selection of display classes for an operating unit In that way you can distribute the messages selectively between different display units You can assign the messages different priorities when configuring ALARM S messages as well The priorities are handled in precisely the same way as you are familiar with from the message bit procedure For more precise details please consult your ProTool documentation Tip Make sure that you assign messages that can bring about consequential errors a higher priority than the consequential errors Tip After additional configuration of a suitable filter on the message screen refer to Defining filter criteria message screen Chapte

Diagnosis ProAgent User s Manual Issue 12 99 3 1 Introduction Avoiding Problems Many problems can be avoided from the outset The flexibility of the process diagnosis system enables potential problems in the process sequence to be identified before they actually occur A worn tool for example is normally signaled by an increase in the forces involved The process diagnosis system can monitor those forces and initiate replacement of the tool at the appropriate time Identifying Problems Problems can still be identified without a process diagnosis The SIMATIC operating units allow you to visualize installations that is display them and to control them with ease A powerful message system draws your attention to process faults An error message appears on the operating unit as an indication Rectifying Problems 3 2 Situation relevant information assists you in locating the fault When problems occur in the process sequence you can easily retrace the faults to the units from which they originate To do so you can examine on the operating unit the logical operation results in the statement list or ladder diagram You don t have to connect up a PU And the fault can be located just as quickly You can quickly remedy the problem You can selectively initiate movements on the operating unit to remedy the problem If a number of installation components have been damaged this is indicated on the operating unit and you
