Hi. This is my first post here. I'll probably be making a few more in the next couple weeks, as I'm developing some internal training materials on Foxboro equipment for our I&C Engineers. Our company does AE work / consulting for modifications / Spec writing for various nuke plants, who have various vintages of existing DCS equipment (usually Foxboro). We often see 51 series, Solaris workstations, etc. Sometimes we'll elect to go forward with small expansions on this legacy of equipment; other times we'll upgrade to the latest MESH hardware / software. I came across the below post (notably older - 2002) from this group, while trying to research the roles of AW's / AP's / WP's / etc. in the overall architecture. I realized that I don't have a complete grasp of the different terminology between AW/AP/WP -- especially the part about "the AW's WP name". Is this purely an artifact of the Sun Solaris, with one box hosting the applications, and another connected to it to provide display / HMI through the X Windowing system? Also: are these terms still used in the same meaning on today's latest equipment? Secondly: Can anyone provide a summary of what network processes take place when "hosting" a CP or FBM? If a power interruption occurs and a CP / FBM needs to reboot, will it have the config files that it needs in non-volatile memory, or is it absolutely essential that the AP/WP be online and available in order to reboot? (i.e. Windows can't have crashed, etc.) I haven't been able to find these types of answers in publicly-available Invensys documents; I'm in the process of signing up for IPS access. Any pointers to literature would be great. Thanks in advance!

First, how did you install WP and AW? What is the AW's logical name (letterbug). AW7001? and what is the _AW_'s wp name. AWWP01? (nice to put AW in there so you don't get confused) The AW basically has two components a host (or application processor) and a workstation (or workstation processor). The host (AP part) is the AW's letterbug. The worstation (WP part) is the AW's secondary letterbug. Then you have a second machine with just the WP part (call the WP). It'll have it's own _separate_ letterbug. WP7001? Then you'll have node on which they are connected. Make sure this is an ethernet node (if that's appropriate for you: no dnbi/dnbt's). What are your AW's letterbugs? What is your WP's letterbug? What is the node type? It's been a year since I've done this so forgive me if some of my terminology is off. Feel free to correct me someone. chris. _______________________________________________________________________ This mailing list is neither sponsored nor endorsed by Invensys Process Systems (formerly The Foxboro Company).
