Interpretation of System Message in AC450 On-line Builder
After an upgrade of an 800xA system to v6.0.3 where one AC450 is connected I receive a system message every 10 minute in On-line Builder. See attached files.
The only thing I've done code wise in the AC450 is to add 8 DS but they are not activated.
So I need help with the interpretation of the System Message.
MVI is Multi Vendor Interface, MviStb messages come from a PLC interface usually. MviSTb1 is PLC interface 1. Check the manual that comes with the interface configured on board 7.
eg if this is a Modbus interface on CI532 then the trace number for H'70019 is "Illegal data request". The register address is 3 and the number of registers is H'A43 (which is far too many). If its not a Modbus link you'll need to check the relevant manual for error message descriptions.
Are you sure this is a new message ?
