7.4.8.5Fieldbus parameters

RS-485 communication status (I6.10.1)

With this function you can check the status of the RS 485 bus. If the bus is not in use, this value is 0.

xx.yyy

xx= 0 – 64 (Number of messages containing errors) yyy = 0 – 999 (Number of messages received correctly)

Fieldbus protocol (P6.10.2)

With this function you can select the fieldbus communications protocol.

0 = Not used

1 = Modbus protocol

Slave address (P6.10.3)

Set here the slave address for the Modbus protocol. You can set any address between 1 and 255.

Baud rate (P6.10.4)

Selects the baud rate used with the Modbus communication.

0 = 300 baud

1 = 600 baud

2 = 1200 baud

3 = 2400 baud

4 = 4800 baud

5 = 9600 baud

6 = 19200 baud

7 = 38400 baud

8 = 57600 baud

Stop bits (P6.10.5)

Set the number of stop bits used in Modbus communication

0 = 1 stop bit

1 = 2 stop bits

Parity type (P6.10.6)

Here you can select the type of parity checking used with the Modbus communication.

0 = None

1 = Odd

2 = Even
