Patrick, * Batch read error messages are an old problem, WITHOUT impact on = production. * No concurrent switch of master/backup role occurs with the same = frequency (once a month) * Nodebus network and batch network are separated: each AW51 has 3 eth = ports: nodebus, batch network and one dedicated to batch redundancy; = RedCfg file is properly configured to avoid batch programs using = nodebus. * Read and Write delta new values were suggested by EMEA (in principle I = had yr same doubts) * after switching, new master collects the same read errors Really, in the last 6 months we suffered nodebus comms failures, that = made worse BatchSuite problems. Cyano measurements on graphic displays froze the screen until DNBT = reset... Once we replaced DNBTs, some old CPs, copper node extension with fiber, = then nodebus performance became acceptable. On the contrary, BatchSuite hasn't got benefit from hardware changes, = only the mentioned 3 software updates mitigates its problems.=20 Alessandro -----Original Message----- From: foxboro-bounce@xxxxxxxxxxxxx [mailto:foxboro-bounce@xxxxxxxxxxxxx] = On Behalf Of Patrick VALENTIN Sent: gioved=EC 19 luglio 2007 10.20 To: foxboro@xxxxxxxxxxxxx Subject: [foxboro] RE : FoxAPI issue. Hi Alessandro, It's look like a network problem ??? Is your nodebus loading OK ? Have you got a separation between nodebus network and batch network (on a second network on second ethernet card) ? Are you switching from the master batch server to slave batch server when problem occur ? If server are switching, I would like to know if the new master (slave before switch) have got immediately the same problem ? If it's a network problem, your Read and Write delta value (0.49) increases the problem.

Hi, We are suffering the same problem: every 6-8 hours MessageDisplay window is flooded by hundreds of "LBUG IADriver read failed for C:B.P (AIS = =3D3D mreaidx)" messages. The problem persists since the Batch Suite 8.0 first installation =3D3D (redundant). It happens when batch server lost communication on the nodebus: operator sees -for few seconds- cyano measurements on graphic displays. I don't count events associated to CP checkpoints.... Apart some hardware enhancements, we recently focused on software: 1) foxapi changed to 4.2.8 2) Read and Write delta (EnvEdit/IADriver)changed from default (1.0) to =3D3D 0.49 3) QF2000627 installed Really, we expected more benefits: the problem still exists, but no = =3D3D impact on production. Unfortunately, in the last months we suffered other BatchSuite problems, =3D3D one of them is when some tags are correctly read, but not evaluated: recipe execution = =3D =3D3D waits until=3D3D20 manual force occurs. Local Foxboro support is involved, EMEA included. Any suggestion is welcome. 2 AW51 style E, rev.6.3 3 WP51 style D 10 CP40s, CP60, 3 ModGtw DM used (transition to FV) Alessandro =3D3D20 =20 =20 _______________________________________________________________________ This mailing list is neither sponsored nor endorsed by Invensys Process Systems (formerly The Foxboro Company).
