6.2 Test of DC synchronicity
DC synchronicity is only available in the "Operational" state.
Test of DC synchronicity in »PLC Designer«
• EtherCAT master: Diagnostic Master tab
"DC In-Sync" is set (TRUE) if the DC master and all DC slaves have been synchronised.
 Diagnostic tabs of the EtherCAT master ( 164)
• Function block L_ETC_GetMasterDiagnostic (FB) ( 144) / Visualisation of the function block
L_ETC_GetMasterDiagnostic ( 166)
"DC In-Sync" is set (TRUE) at the oDiagnostic.xDC_InSync output if the DC master AND all DC
slaves are synchronised.
• Function block L_IODrvEtherCAT (FB) ( 140)
"DC In-Sync" is set (TRUE) at the xDistributedClockInSync output if all DC slaves are synchronised.
Test of DC synchronicity in »WebConfig«:
In the code
C281/5 , "DC In-Sync" is set (TRUE) if all DC slaves have been synchronised.
