LinkLayer104: Wrong frame sequence (received #XXX, expected #YYY), disconnecting...

Modes Master and Slave. This message reports receiving a message out of order in protocol IEC 870-5-104. When this Driver detects that situation, forces a reconnection. Its cause is probably a message lost in the network. To solve it, investigate the physical connection or the network between this Driver and the device

ERROR: Failed to send command 'XXX', application layer is locked

Only in Master mode. This message occurs when this Driver tries to send a Command at application level while another Command is already executing. For example, trying to send a Select or Execute Command while a General Interrogation Command is executing. This Driver only generates that message and quits sending the Command after waiting for the time specified by the application's time-out. The cause is that the Application Layer of this Driver is locked for a long time. To solve it, increase the application's time-out

GeneralInterrogation: received actterm with no GI active, retrying last GI

Only in Master mode. This message occurs when this Driver receives a confirmation of finishing a General Interrogation Command and there is no active general interrogation process. Causes can be a General Interrogation Command started previously by this Driver which was interrupted due to a problem with device's connection or this Driver is configured to not wait for a notification of finishing a General Interrogation Command and the Slave is sending that finishing notification. Possible solution are increase application's time-out of this Driver, investigate what caused the problem with device's connection, or configure this Driver to wait for the finishing of the General Interrogation Command, and also possibly consider increasing application's time-out of this Driver
