Option 13, operating mode

Operating mode
The operating mode determines if the interface is to be
operated half duplex (RS485) or full duplex (RS422).
• 0x00: Half duplex - two-wire operation (RS485)
Half duplex operation means that either transmission or
reception can take place at a time. The data are
transmitted between the communication partners
alternately in both directions.
In case of the half duplex parametersetting under RS485,
no software data flow control is possible.
• 0x01: Full duplex - four-wire operation (RS422)
The data are exchanged simultaneously between the
communication partners; transmission and reception can
take place at the same time. Each communication partner
must simultaneously actuate a receive path.
