4.9.2.3.2. Program example: read diagnostic data This example is to illustrate the typical process of requesting a service: ; Read diagnostic data of DP slave 1 ; Data interface: SBM2.00... ; In this example, the task is started by the following marker: ; - SM00.07 ; ****************************************************************************** ; —— Is there an active task already? L DIA_TASK SBM02.00 ; (diagnostic data in task byte) CMP 0 JP= NEW_TASK ; all bits=0: no task JP DP_CONT ; else: restart KUBES module ; —— New task requested? ; Activate NEW_TASK L S1_DIAG SM00.07 ; (task slave 1: read diag. data) JPCN END ; request no diag. data -> jump ; —— Start service START L 9 ; service 9 = DIA_TASK SBM02.00 ; (diagnostic data in task byte) L 1 ; station1 = DIA_PB# SBM02.02 ; (station number diag. data) L 31 ; number of diag. data bytes = DIA_LEN SBM02.03 ; (length data field diag. data) ; —— Start KUBES module DP_CTRL DP_CONT JPK DP_CTRL , _____ DIA_TASK -|_____|- ; Poll task status L DIA_TASK SBM02.00 ; (diagnostic data in task byte) JPB FAILURE ; bit7=1: error CMP 0 JP= OK ; all bits=0: task completed JP END ; task not completed ; —— Task completed, clear task markers OK =0 S1_DIAG SM00.07 ; (task: read diag. data of slave 1) JP END ; —— Error evaluation FAILURE L DIA_FAIL SBM02.01 ; (error byte diag. data) END NOP 4 - 52
4.9.2.4. Service 7: activate/deactivate DP slave PC Control 645-12M on PROFIBUS This services allows you to remove specific DP slaves from (deactivate) or add to (activate) the master's poll list (deactivate). The master entertains no cyclic data communication with deactivated slaves. If a slave is re-activated, the master sends the appropriate device parameter as if it was a new start-up procedure. Parameter field Byte Parameter 0 B yte 1 Error# Input Descriptio n Service 7 Specifies the service 0 No error 1 Parameter error 7 Internal error B yte 2 Station# 0...99 Number of DP slave Byte 3 Action 0...127 Deactivat e 128...255 Activate The Activate command also enables data communication even if the relevant slave has been defined to be "passive" at start-up (see chapter "4.9.2.3.1. Choosing a station and group"). 4 - 53
