The SIDirect Communication Driver generates messages that you can use for diagnostic purposes. These DASTrace diagnostic messages do not necessarily indicate that error conditions exist.
The following table is not a complete list of messages that are shown in the Logger when DASTrace is enabled. Other diagnostic messages are shown, as well.
Note: The logger messages use the following codes: %s to represent strings, %d to represent numbers (integer), %x to represent the address of the object, and %ums to represent time in milliseconds.

Logger Message |
Explanation |
Probable Cause |
Solution |
|
Message is in SlowPollMode (%s msg=0x%08X) for topic %s |
The message state is set to Slow poll interval. |
The response for this message has not been received by the server. Either the response time is very small or the PLC is very busy. |
Adjust the message reply timeout in the server in accordance with the performance of the PLC to achieve the optimal behavior. |
|
Message leaves the SlowPollMode (%s msg=0x%08X) for topic %s |
The message state is coming out of the Slow poll interval. |
The server recovered from the error situation. |
N/A |
|
UpdateInterval for Device Group: %s changed to %d |
The update interval for the device group has been changed. The messages are now to be polled at a new update interval for this device group. |
N/A |
N/A |
|
Setting all items to bad in hierarchy: %s |
The server updates the status of all the items as Bad on this connection. |
The connection with the PLC is broken. |
Check the connection with the PLC. |
|
Connection with '%s' dropped, restarting connection |
The socket connection with the PLC fails due to a given error code: "The PLC initiated termination of the Socket Connection." |
The PLC is not responding to the Connect request from the Communication Driver. |
The SIDirect Communication Driver will attempt to automatically reconnect. No user action is required. |
|
Connection with '%s' dropped while pending, going to slow poll |
The socket connection with the PLC fails due to a given error code: "The PLC initiated termination of the Socket Connection." |
The PLC has been disconnected and/or has faulted. |
Check the PLC connection and clear any outstanding PLC faults. |
|
Block receive size: doesn't match msg size |
The server receives an invalid block packet from the PLC. |
This message from the PLC is garbled. |
Check the PLC health status and the network condition. |
