p2024[0...2] Fieldbus interface times / Fieldbus times
CU250S_V Access level: 3
Can be changed: U, T
Unit group: -
Min
0 [ms]
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).
r2029[0...7] Field bus interface error statistics / Field bus error
CU250S_V Access level: 3
Can be changed: -
Unit group: -
Min
-
Description: Displays the receive errors on the field bus interface (RS485).
Index: [0] = Number of error-free telegrams
[1] = Number of rejected telegrams
[2] = Number of framing errors
[3] = Number of overrun errors
[4] = Number of parity errors
[5] = Number of starting character errors
[6] = Number of checksum errors
[7] = Number of length errors
p2030 Field bus interface protocol selection / Field bus protocol

Can be changed: T
Unit group: -
Min
0
Description: Sets the communication protocol for the field bus interface.
Value: 0:
1:
2:
Note: Changes only become effective after POWER ON.
The parameter is not influenced by setting the factory setting.
