Communication settings

The following settings can be performed:

Configuration Object Value range Factory settings
Slave address 2028h 1 to 247 5
Baud rate 202Ah 7200 to 256000 19200
Parity 202Dh
  • None: 0x00
  • Even: 0x04
  • Odd: 0x06
0x04 (Even)
The number of data bits is always "8" here. The number of stop bits is dependent on the parity setting:
  • No parity: 2 stop bits
  • "Even" or "Odd" parity: 1 stop bit

The following baud rates are supported:

  • 7200
  • 9600
  • 14400
  • 19200
  • 38400
  • 56000
  • 57600
  • 115200
  • 128000
  • 256000

The slave address and baud rate can also be defined via the analog input, see Setting slave address and baud rate

You must save the changes by writing value "65766173h" in object 1010h:0Bh. The changes are not taken over until after the controller has been restarted.
