Re: FoxCOM This is the name of the protocol used between our FBMs and our I/A Series Intelligent Field Devices. It is similar in function to HART, but faster. The protocol used to communicate over our control network is usually referred to as "COMEX/IPC".

Was RCNI, NCNI, FO SWITCH Thank you Tom VandeWater and Alex Johnson for your very good information. To further clarify on my RCNI, NCNI and switches question AW70 connects to RCNI (using Y cable) >> YES RCNI connects to 100FX FO switch >> Needs to connect to two seperate switches for redundancy, and I heartily agree with Alex Johnson that the extra money for the FO switch will be well worth it. he Media converters are a pain. FO switch connects to a switch which has a single 100FX FO uplink port, the other ports RJ45 10/100TX >> This should work but again need two for redundancy 10/100TX RJ45 switch connects to RJ-45 port on NCNI (according to document NCNI had RJ45 AND MT-RJ port) >> NCNI does have both RJ45 and MT-RJ port. Need two NCNI's NCNIs in 1x8 rack >> NCNI's switch settings define bus. Set one to "A" and other to "B" CP60s in 1x8 rack >> YES (the above switches in duplicate for redundant) >> YES Will this work ok? >> My belief is yes but I am concerned that we may not know the rest of the story because of the advisory that Graham Heath mentioned in his previous note. I was unable to find the advisory but it sound like there are some contradictions to the B0400DV Rev. A I/A Series A2(tm) High Performance System Network User's Guide. I think this better because no need for media converters, cost should be less and seems better solution. My only worry is if Foxboro uses some communications protocol that will not work with standard Ethernet switches? >> The document linked below shows several methods of interconnections which lead me to believe that there isn't anything in Foxboro's protocol, (FoxCOM), that would prevent it from working on standard ethernet equipment. Again, the advisory could contradict this! http://ips.csc.invensys.com/content/Documents/IASeries/b0400/B0400DV_A.pdf >> I agree and like your arrangement. It has a lot of connection flexability with both a FO and RJ-45 switch. The future CP's, workstations, and fieldbus connections will be easily made with this arrangement.
