RET_VAL (Return value)Error code Description0000h No error occurred.8081h (only with MODE = 2 or 3)You have assigned the value 0 to SI_ID.8082h (only with MODE = 1)You have assigned one of 0 different values to SI_ID.8084h You have assigned an illegal value to MODE.8085h SFC 106 is currently being processed.8086h Not all selected system resources could be deleted because at least one of them was being pro-cessed when SFC 106 was called.8xyyh General error informationÄ Chap. 4.2 ‘General and Specific Error Information RET_VAL’ page 6614.1.61 SFC 107 - ALARM_DQ and SFC 108 - ALARM_DWith every call the SFCs 107 ALARM_DQ (Generating Acknowledgeable Block RelatedMessages) and 108 ALARM_D (Permanently Acknowledged Block Related Messages)generate a message to which you can append an associated value. Thus, you corre-spond with SFCs 17 ALARM_SQ and 18 ALARM_S.When generating messages with SFCs 107 ALARM_DQ and 108 ALARM_D, the oper-ating system temporarily occupies a system resource for the duration of the signal cycle.The signal cycle time for SFC 108 ALARM_D starts at the SFC call with SIG = 1 andends at a new call with SIG = 0. This interval for SFC 107 ALARM_DQ may be extendedby the time expiring until the incoming signal is acknowledged at a logged in displayingdevice.For SFC 108 ALARM_D, the signal cycle lasts from the SFC call SIG = 1 until anothercall with SIG = 0. For SFC 107 ALARM_DQ, this time period also includes the time untilthe incoming signal is acknowledged by one of the reported display devices, if necessary.If, during the signal cycle, the message-generating block is overloaded or deleted, theassociated system resource remains occupied until the next restart.The additional functionality of SFCs 107 ALARM_DQ and 108 ALARM_D compared toSFCs 17 and 18 is now that you can manage these occupied system resources:n With the help of SFC 105 READ_SI you can fetch information related to occupiedsystem resources.n With SFC 106 DEL_SI you can release occupied system resources again. This is ofspecial significance for permanently occupied system resources. A currently occupiedsystem resource, for example, stays occupied until the next restart if you, in thecourse of a program change, delete an FB call that contains SFC 107 or SFC 108calls. When you change the program, and reload an FB with SFC 107 or SFC 108calls, it may happen that the SFCs 107 and 108 do not generate anymore messages.The SFCs 107 and 108 contain one parameter more than the SFCs 17 and 18, namelythe input CMP_ID. Use this input to assign the messages generated with SFCs 107 and108 to logical areas, for example to parts of the system. If you call SFC 107/SFC 108 inan FB the obvious thing to do is to assign the number of the corresponding instance DBto CMP_ID.DescriptionDescription ParameterVIPA SPEED7 Integrated StandardSystem Functions > SFC 107 - ALARM_DQ and SFC 108 - ALARM_DHB00 | OPL_SP7 | Operation list | en | 18-30 727
