Parameters
List of Parameters
p2016[0...3] CI: Comm IF USS PZD send word / Comm USS send word
Access level: 3
Can be changed: U, T
Units group: -
Min
-
Description: Selects the PZD (actual values) to be sent via the commissioning interface USS.
The actual values are displayed on an intelligent operator panel (IOP).
Index: [0] = PZD 1
[1] = PZD 2
[2] = PZD 3
[3] = PZD 4
r2019[0...7] Comm int error statistics / Comm err
Access level: 4
Can be changed: -
Units group: -
Min
-
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
p2020 Field bus interface baud rate / Field bus baud
CU240B-2 Access level: 2
CU240E-2
Can be changed: T
CU240E-2 F
Units group: -

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 SS: 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
