Hi Alex With reference to minimum BPC Will the FCP280 have the same exclusions as the FCP270 and CP60 where 0.5 second BPC is the minimum when FDSI and their forerunners FBM224/223 are implemented Shaun -----Original Message----- From: foxboro-bounce@xxxxxxxxxxxxx [mailto:foxboro-bounce@xxxxxxxxxxxxx] On Behalf Of Johnson, Alex Sent: Wednesday, 12 February 2014 10:57 a.m. To: foxboro@xxxxxxxxxxxxx Subject: Re: [foxboro] upgrade path Frits, Migration is a long topic. I'll see if I can get some folks in touch with you. Re: Replacing the CP60 first with a CP270 First comment - the FCP280 will be released by June. I suspect you will use it. There are a lot of good things about the CP280, but two of interest to your questions are that: * It is twice as fast as the CP270 which was twice as fast as the CP60. * It has four independent PIO bus ports that can run independently at either: + 2Mbps (to support 200 Series I/O) or + 268Kbps (to support 100-Series I/O). Re: Replacing the CP60 first with a CP270 will put the fieldbus back to 268Kbps for the 100 series I/O. Is this an issue? The change in baud rate is not an issue. The CP60 queries the FCMs for FBM data. The FCM to 100-Series FBMs is a standard 268Kbps link so in general overall throughput should improve when you move to the new CP because the intermediate FCM is eliminated. However, the wiring change is a pain and it can be an issue if the FCMs are remotely located. We have solutions and wiring diagrams in the documentation, but that's where the pain is. Re: There are two CP60s at 0.1BPC, one for high accuracy position control of sample lances and one for high density data collection. Can a CP270 comfortably run at 0.1BPC? If the CP60 could do it, the CP2x0 can do it better. In fact, we can run the FCP280 (or FCP270) at 50ms if that would be of benefit. _____________________________________________________________________________________ Alex Johnson | Schneider Electric | Invensys | United States | System Architect - Next Generation Systems Phone: +1 713 329 8472 | Fax: +1 713 329 1700 Email: alex.johnson@xxxxxxxxxxxx | Site: www.invensys.com | Address: 10900 Equity Drive, 77041 Houston, TX, United States *** Please consider the environment before printing this e-mail -----Original Message----- From: foxboro-bounce@xxxxxxxxxxxxx [mailto:foxboro-bounce@xxxxxxxxxxxxx] On Behalf Of Schouten, Frits JF Sent: Tuesday, February 11, 2014 2:22 PM To: foxboro@xxxxxxxxxxxxx Subject: [foxboro] upgrade path Hello all, Is there a right way or an absolute wrong way to do an upgrade from Version 7.x with a mix of 100 and 200 series I/O to Version 8.x with only 200 series I/O? We have pretty much only one 24hr stop every two months and perhaps one 4-6hr stop a week, so it will be a live upgrade. Currently I have two Version 7.x systems of which one still has a CP30 in the mix of CP60s with both 100 and 200 series I/O. The other Version 7.x system has only CP60s with a mix of 100 and 200 series I/O. Those two systems are linked at NodeBus level. The CP60s talks 10Mbps to the FBMs. Replacing the CP60 first with a CP270 will put the fieldbus back to 268Kbps for the 100 series I/O. Is this an issue? There are two CP60s at 0.1BPC, one for high accuracy position control of sample lances and one for high density data collection. Can a CP270 comfortably run at 0.1BPC? The CP30 can be engineered out with its I/O moved to a CP270 so, that shouldn't be an issue. Any thoughts or ideas on how to skin this cat?
