The WEBSVC Communication Driver supports same diagnostic system items as other AVEVA Communication Drivers, along with the following protocol specific system item:
|
Name |
Type |
Description |
|
$sys$diagnosticlogging |
VT_UI4 |
When poked, turns on runtime logging. (Read Only) Note: Flag values can be added together to enable multiple at the same time. i.e. 1+8 = 9 which enables INFO and TRACE. |
The WEBSVC Communication Driver also provides additional logging capability. This capability can be turned on using a system tag named $sys$diagnosticlogging.
Diagnostic logging records the previous three hours. The log lines are output to a file on disk in the WEBSVC Communication Driver data folder:
C:\ProgramData\Wonderware\OI-Server\$Operations Integration Supervisory Servers$\OI.WEBSVC\LogFiles
