FV does NOT use FoxAPI or AIM*API. The trend is to maximize the use of FoxAPI or AIM*API in all new applications as opposed to using the OM API. Such applications include: Application Object Services DMCplus Bridge Connoisseur Bridge AIM*OPC Server WonderLink etc, etc Regards, Alex Johnson Invensys 10707 Haddington Houston, TX 77063 713.722.2859 (office) 713.722.2700 (switchboard) 713.932.0222 (fax) ajohnson@xxxxxxxxxxx <mailto:ajohnson@xxxxxxxxxxx> For the latest information on ArchestrA, go to www.invensys.com/Archestra.html <http://www.invensys.com/divisions/Archestra.html> . -----Original Message----- From: stan [SMTP:stanb@xxxxxxxx] Sent: Thursday, December 12, 2002 12:00 PM To: foxboro@xxxxxxxxxxxxx Subject: Re: [foxboro] FOXAPI Configuration for Foxhistory Ver 2.0 On Thu, Dec 12, 2002 at 12:30:00PM -0500, Johnson, Alex (Foxboro) wrote: > > The OM API does not supply a call to change the scan rate on the list.

However, I was under the impression that only "external" tasks (PI being an example) and the historian used the FoxAPI. Am I mistaken? Do graphics pages for example, and CP to CP connections use the FoxAPI? Or if they don't, might that be a long term design goal? -- "They that would give up essential liberty for temporary safety deserve neither liberty nor safety." -- Benjamin Franklin _______________________________________________________________________ This mailing list is neither sponsored nor endorsed by Invensys Process Systems (formerly The Foxboro Company).
