7.2.8 Error code of XGT communication
If XGT client transmits the request frame to server, server analyzes the received frame. If frame is suited for XGT protocol,
it transmits the ACK response frame and if frame is not suited for XGT protocol, it transmits the NAK response frame
including the error code.
The following table describes the error code included in the NAK response.
Error code is displayed as hex 2 byte (4 byte as ASCII code). The user can see error by frame monitor and in case of
viewing by ASCII, the user can see the following error code.
