Communication Driver Log Flags

Messages created for these log flags are for Communication Driver common components and contain information about internal Communication Driver activities.

• DACmnProtFail: Some failure occurred in the common components while sending a message, updating an item, or otherwise moving data. Typically, this represents some unexpected behavior in the server-specific DLL.

• DACmnProtWarn: Some problem occurred that interfered with sending messages, updating items, or otherwise moving data. Common examples are slow poll, value limiting during type conversion, and transaction timeout messages.

• DACmnTrace: Normal processing of client program requests and data movement to and from the server-specific DLL are traced on this log flag. Use this in conjunction with DACmnVerbose to get the most information.

• DACmnVerbose: Many log flags used by the DAS common components are modified occasionally by DACmnVerbose. When DACmnVerbose is set, the logging of messages on other log flags includes more information.

• DACmnSend: Operations within the DAS Engine DLL that revolve around sending messages to the server-specific DLL.

• DACmnReceive: Events surrounding messages that are returned to the DAS Engine by the server-specific DLL, including the blocking and unblocking of hierarchies.
