Index: [0] = PZD 1
[1] = PZD 2
[2] = PZD 3
[3] = PZD 4
Description: Displays the receive errors at the commissioning interface (USS, RS232).
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
Description: Sets the baud rate for the field bus interface (RS485).
Value: 4: 2400 baud
5: 4800 baud
6: 9600 baud
7: 19200 baud
8: 38400 baud
9: 57600 baud
10: 76800 baud
11: 93750 baud
12: 115200 baud
13: 187500 baud
Notice: For p0014 = 1, the following applies:
After the value has been modified, no further parameter modifications can be made and the status is shown in r3996.
Modifications can be made again when r3996 = 0.
For p0014 = 0, the following applies:
Before a changed setting becomes permanently effective, a non-volatile RAM to ROM data save is required. To do
this, set p0971 = 1 or p0014 = 1.
Note: Fieldbus IF: Fieldbus interface
Changes only become effective after POWER ON.
The parameter is not influenced by setting the factory setting.
The parameter is set to the factory setting when the protocol is reselected.
When p2030 = 1 (USS), the following applies:
Min./max./factory setting: 4/13/8
When p2030 = 2 (MODBUS), the following applies:
Min./max./factory setting: 5/13/7
If p2030 = 5 (BACnet), the following applies:
Possible values/factory setting: (6, 7, 8, 10) / 6
If p2030 = 8 (P1), the following applies:
Min./max./factory setting: 5/7/5
