14.2.16 SFB 36 - NOTIFY - Messages without acknowledgement displayGenerating block-related messages without acknowledgement display.n SFB 36 NOTIFY monitors a signal. It generates a message both on a rising edge(event entering state) and on a falling edge (event leaving state) with associatedvalues.n When the SFB is first called, a message with the current signal state is sent. Themessage is sent to all stations logged on for this purpose.n The associated values are queried when the edge is detected and assigned to themessage.Parameter Declaration Data type Memory block DescriptionSIG INPUT BOOL I, Q, M, D, L The signal to be monitored.ID INPUT WORD Constant(I, Q, M, D, L)Data channel for messages: EEEEh.ID is only evaluated at the first call.EV_ID INPUT DWORD Constant(I, Q, M, D, L)Message number (not allowed: 0)SEVERITY INPUT WORD Constant(I, Q, M, D, L)Weighting of the eventDONE OUTPUT BOOL I, Q, M, D, L Status parameter DONE:Message generation completed.ERROR OUTPUT BOOL I, Q, M, D, L ERROR status parameterSTATUS OUTPUT WORD I, Q, M, D, L STATUS parameter:Display of an error informationSD_i IN_OUT ANY I, Q, M, D, T, C i-th associated valueThe signal to be monitored.Data channel for messages: EEEEh. ID is only evaluated at the first call.EV_ID is only evaluated at the first call. Subsequently, the message number used for thefirst call applies to every call of SFB with the corresponding instance DB. The messagenumber is automatically assigned by the Siemens STEP®7 programming tool. So the con-sistency of the message numbers is guaranteed. The message numbers within a userprogram must be unique.Weighting of the event Here the value 0 is the highest weighting. This parameter is irrele-vant for processing the message. Possible values: 0 ... 127 (default value: 64)Status parameter DONE: Message generation completed.DescriptionParameterSIGIDEV_IDSEVERITYDONEVIPA SPEED7 Integrated StandardSystem Function Blocks > SFB 36 - NOTIFY - Messages without acknowledgement displayHB00 | OPL_SP7 | Operation list | en | 18-30 759
