2 Parameters
2.2 List of parameters
Description: Sets the number of 16-bit words in the PZD part of the USS telegram for the field bus interface.
Dependency: Refer to: p2030
Note: The parameter is not influenced by setting the factory setting.
Description: Sets the number of 16-bit words in the PKW part of the USS telegram for the field bus interface.
Value: 0: PKW 0 words
3: PKW 3 words
4: PKW 4 words
127: PKW variable
Dependency: Refer to: p2030
Note: The parameter is not influenced by setting the factory setting.
Description: Sets the time values for the fieldbus interface.
For Modbus the following applies:
p2024[0, 1]: Not relevant.
p2024[2]: Telegram pause time (pause time between two telegrams).
Index: [0] = Max. processing time
[1] = Character delay time
[2] = Telegram pause time
Dependency: Refer to: p2020, p2030
Note: For p2024[2] (Modbus):
If the field bus baud rate is changed (p2020), the default time setting is restored.
The default setting corresponds to a time of 3.5 characters (dependent on the baud rate that has been set).
Description: Displays the receive errors on the field bus interface (RS485).
