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 = mreaidx)" messages. The problem persists since the Batch Suite 8.0 first installation = (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 = 0.49 3) QF2000627 installed Really, we expected more benefits: the problem still exists, but no = impact on production. Unfortunately, in the last months we suffered other BatchSuite problems, = one of them is when some tags are correctly read, but not evaluated: recipe execution = waits until=20 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 =20 -----Original Message----- From: foxboro-bounce@xxxxxxxxxxxxx [mailto:foxboro-bounce@xxxxxxxxxxxxx] = On Behalf Of Wilbur Ho Sent: mercoled=EC 18 luglio 2007 22.24 To: foxboro@xxxxxxxxxxxxx Subject: [foxboro] FoxAPI issue. Hi All, =20 I am running FoxAPI 4.2.6 on IA version 6.4. I am also running I/A = Batch 8.0 which gets its data from the FoxAPI. I keep getting the message = "ERROR read failed C:B:P (AIS mreaidx)" in the Batch logger. The tags, however = can be seen in foxspy, and ProcStatus of Batch. =20 Any suggestions? =20 Wil =20 =20 =20 =20 _______________________________________________________________________ This mailing list is neither sponsored nor endorsed by Invensys Process Systems (formerly The Foxboro Company).
