FB_GseByteOrderConverterClass
The natural byte order of the data on a TwinCAT system is referred to as the host byte order. The byte order of the data transmitted over the network is referred to as the network byte order. The network byte order of IEC 61850 data largely corresponds to the big-endian format, while the TwinCAT system uses the byte order of the little-endian format. This function block implements methods that allow the byte order of the IEC 61850 data to be changed (little-endian <-> big-endian).
The HostToNetXxx methods convert (encode) the data values to be sent from host byte order to network byte order. After encoding, the data values are stored in the network transmission buffer of the sender (e.g., SV-Publisher). The transmitter sends the contents of the network transmission buffer.
The receiver (e.g., SV subscriber) receives the data values into the network receive buffer. The NetToHostXxx methods convert (decode) the data values in the network receive buffer from network byte order to host byte order.
