The length byte

It can be configured whether the send length is also stored as a byte in the input / output data
area (Fieldbus lengthbyte -> active). As many bytes are sent in the send direction as are speci-
fied in this byte. When a telegram is received, the gateway enters the number of characters
received.

Swap word

When "Swap word" is activated, the data is exchanged word by word to and from the fieldbus.
I.e. High and low bytes in a 16 bit word are exchanged and transferred to the CAN bus.
It affects the entire fieldbus buffer.
