Ethernet/IP driver details

Debug levels

The following can be used to select which types of debug information are sent to the log viewer:

Debug Level (-dbg) Description
2 Informs about the driver operation in detail. It is recommended to set this option only when the driver load is low in order not to affect the time performance of the driver.
10 Displays detailed information from the EIP protocol stack.
11 Displays detailed information about poll-group blocks.
25 If you suspect that a polling request has lost its message, this option can be used to show information about matching received data to corresponding data points.
26 Displays queue activity and counts.
27 Periodically displays throughput statistics (total value-changes per second).
-reportAll Displays summary information about all configured PLCs and poll groups.

Error codes – basic error state

Error Code State
0 OK
1 Driver internal
2 Failed to connect
3 Queue overflow - occurs when the output queue for a given PLC has reached maxQueueSize entries.
4 Decoding error - occurs when a received response from the PLC cannot be processed due to error. This can be a response with no matching request, a response with an unexpected error status, a response with an unexpected number of tags or an unexpected request type.
