Cause:
The reception of setpoints from the fieldbus interface has been interrupted.
- bus connection interrupted.
- communication partner switched off.
CU230P-2 DP:
- PROFIBUS master set into the STOP state.
See also: p2040 (Fieldbus interface monitoring time), p2047 (PROFIBUS additional monitoring time)
Remedy:
Ensure bus connection has been established and switch on communication partner.
CU230P-2 BT, CU230P-2 HVAC:
- if required, adapt p2040.
CU230P-2 DP:
- set the PROFIBUS master to the RUN state.
- if the error is repeated, check the set response monitoring in the bus configuration (HW Config).
- slave redundancy: For operation on a Y link, it must be ensured that "DP alarm mode = DPV1" is set in the slave
parameterization.
A01920 (F)
PROFIBUS: Interruption cyclic connection
Reaction:
NONE
Acknowledge:
NONE
Cause:
The cyclic connection to the PROFIBUS master is interrupted.
Remedy:
Establish the PROFIBUS connection and activate the PROFIBUS master in the cyclic mode.
Note:
If there is no communication to a higher-level control system, then p2030 should be set = 0 to suppress this message.

PROFIBUS: Connection to the Publisher failed
Reaction:
NONE
Acknowledge:
NONE
Cause:
For PROFIBUS peer-to-peer data transfer, the connection to at least one Publisher has failed.
Alarm value (r2124, interpret binary):
Bit 0 = 1: Publisher with address in r2077[0], connection failed.
...
Bit 15 = 1: Publisher with address in r2077[15], connection failed.
Remedy:
Check the PROFIBUS cables.

F01946 (A)
PROFIBUS: Connection to the Publisher aborted
Reaction:
OFF1 (NONE, OFF2, OFF3)
Acknowledge:
IMMEDIATELY (POWER ON)
Cause:
The connection to at least one Publisher for PROFIBUS peer-to-peer data transfer in cyclic operation has been aborted.
Fault value (r0949, interpret binary):
Bit 0 = 1: Publisher with address in r2077[0], connection aborted.
...
Bit 15 = 1: Publisher with address in r2077[15], connection aborted.
Remedy:
- check the PROFIBUS cables.
- check the state of the Publisher that has the aborted connection.
