Logging

The driver allows activating a configurable logging of the communication. The logged data is written to the file <name>_LOG.TXT in the project directory and can be read with any text editor.

Logging is activated by creating a section in the project.ini that has the driver name as a name and contains the following entries:

LOG_FLAGS0

Allows to configure the depth of the logging.

Bit/Numerical	Meaning
1/1	Log errors. Always active
2/2	Warnings.
3 /4	Add item will be logged
4/8	Add group will be logged.
5/16	Server starts will be logged.
6/32	Value changes will be logged.
7/64	Item activation will be logged.
8/128	Item deactivation will be logged.
9/256	Event DataChange will be logged.
10/512	Write will be logged.

The sum of the numerical values is the value for 'LOG_FLAGS0='; e.g.:

LOG_FLAGS0=65535

Activates logging for all.

LOGON

Allows to globally switch logging on(1) or off(0); e.g.:

LOGON=1

Complete entry in the project.ini

[OPC Client V2.0]

LOG_FLAGS0=65535
