Both CPU in stop mode: - at first IM153-2 SF blink, ACT off. - at second IM153-2 every thing is OK, ACT on - SF and BF LED at both CPU are off 2. Switch CPU to RUN mode: - SF LED on at both CPU - at first IM153-2 SF blink, ACT off. - at second IM153-2 every thing is OK, ACT on Could anybody tell me what is wrong? i attach my hw config and network picture along with my program. DiagnoseA and DiagnoseB are the event i recorded from diagnose buffer of CPU A and CPU B respectively. Attachment REDUNDANT.pdf (179 Downloads)

But reading your diagnostic buffer entrys: Think you havn't loaded an Instance DB. Looking at the published parts of our program: Have you checked, that the DB 5 is transferred to the PLC?

Notice that the example copde from Khaled's post reads LADDR:=256; the same parameter in the SWR_e manual gives LADDR:=260. This is the range of addresses I would expect. You can look for the base address of the IM 153-2 in Netpro, under connections for the Profibus-DP network. Hope this helps, Daniel Chartier
