– BIT0: RS232<->RS422 – Serial interface physics
With this parameter the interface physics can be set to RS232(0) or
RS485(1).
– BIT1: double Baudrate
Setting this bit doubles the baudrate for the serial interface
Exp: A selected baudrate of 19200 Baud can be increased to 38400
Baud by setting this bit.
– BIT7 – Bit2: reserved.
Trigger character for Serial
triggert mode
Here the trigger character for the serial triggerd mode is set. If the
seriell receive data stream contains the same sign, all received data
up to this character are sent to the DP-Master inclusive the trigger
character.Triggerzeichen eingetragen werden.
