Error in Xenta 527 HyperTerminal
This error happens over and over (with different file sizes each time), and the controller essentially locks up and requires a restart to recover.
TAC Vista, TAC INET
- TAC Vista below version 5.15
- Xenta 527 using Controller LAN (RS-485) I/NET
Vista will poll I/NET for the past 1000 entries. Normal internal events consist of much less data than the I/NET events; 1000 I/NET events in one message make the message too large. The VSD Response too large error indicates Xentas max message size has been reached. TAC Vista ignores the error and repeatedly tries, leaving the Xenta 527 stuck in a loop.
Polling I/NET for fewer events fixes this problem. The max number of events in one message has been adjusted down to 400. This change is included in TAC Vista revisions 5.1.5 HotFix 16 and later.
