Dear FAQ Expert, I've seen the german thread and I was going to write to you to make it in english conferences but I'm glad that you were faster. I know that this conference about FAQs but you also mentioned online support.
So, I hope you just take a look at Software Redundancy, New Version 1.2 Now Available 1- The entry wascreated in 2003 and I think usable moduleslist (CPUs)should be updated to contain DP/PN CPUs. Many people ask if these CPUs will work with software redundancy or not. (They don't know that it works because it's just not listed) 2- Thelist should also have ET200iSP. 3- Also many people frequently ask if Profinet interface of PN CPUs can be used for redundant link or not. 4- Hundreds of people asked and still ask if Y-Link can be used with software redundancy or not. I wish to see updated manual of software redundancy and updated usable modules list and new FAQs. Best regards and wish you luck in your mission. H-H |

Dear all, I've contacted our colleagues which are responsible for the FAQ's, ... There is a newer entry within our Product Support. Please have a look at the following information: Which modules can you use when implementing software redundancy? Hope this is the information you are looking for. Best regards CS Moderator |

Dear CS Moderator thank you for the update,but I fear that that list - while generally helpful and quite rightly also referenced in the SWR manual -is actually one of the main causes ofconfusion for the new or less experienced SWR user. The two main ambiguities in it are: 1.) PN/DP CPU's are listed as supported. While this is correct, it failes to mention thatthe PN port can NOT be used for the redundancy link. Ideally, the SWR team would develop a new FB (e.g .FB106 "SWR_T_COM") as part of the package that uses Open IE communciation via T comms Blocks to alllow usage of the PN portfor the redundancy link. Until such time though,a footnote in the list of supported modules and/or seperate FAQconcerning this would be helpful. 2.) Usage of DP/PA Link and Y-Link. This is NOT offcially supported, however IM153-2's are (of course) listed as supported. SinceDP/PA Link's and Y-Link's comprise of IM153-2's, the only thing to work out that neither DP/PA Link nor Y-Link can be used with SWR is by realising that the required PA-Coupler or Y-Coupler are(correctly) not listed. As such, I do believe that an "offcial" seperate FAQ simply stating "DP/PA Link and Y-Link are NOT supported by SWR" would be a usefulthing to have. Alternatively (and preferably), whatever technical challenges exist tosupport DP/PA Link's and Y-Link'swith SWR could perhaps be overcome (surely this can't be in too hard basket and is just a matter of accomodating the changeover timing, isn't it?). Thirdly, H-Halso mention that ET200iSP do work with SWR. I take his word for it, but haven't tested it myself. If redundant IM152's are in fact offically supported, they are certainly still missing from thelist. Many thanks in advance for passing this on, we've all been good this year (I think), so perhaps Santa can bring us either some newFAQ's or even better, a new SWR version |
