F01662 Error internal communications
Reaction: OFF2
Acknowledge: POWER ON
Cause: A module-internal communication error has occurred.
Fault value (r0949, interpret hexadecimal):
Only for internal Siemens troubleshooting.
Remedy: - carry out a POWER ON (power off/on).
- upgrade firmware to later version.
- contact the Hotline.
A01900 (F) PROFIBUS: Configuration telegram error
Reaction: NONE
Acknowledge: NONE
Cause: A PROFIBUS master attempts to establish a connection using an incorrect configuring telegram.
Alarm value (r2124, interpret decimal):
2: Too many PZD data words for output or input. The number of possible PZD is specified by the number of indices
in r2050/p2051.
3: Uneven number of bytes for input or output.
Remedy: Check the bus configuration on the master and slave sides.
Re alarm value = 2:
Check the number of data words for output and input.
F01910 (N, A) Fieldbus interface setpoint timeout
Reaction: OFF3 (IASC/DCBRAKE, NONE, OFF1, OFF2, STOP2)
Acknowledge: IMMEDIATELY
Cause: The reception of setpoints from the fieldbus interface has been interrupted.
- bus connection interrupted.
- communication partner switched off.
CU230-2P 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 peer.
CU230-2P HVAC:
- if required, adapt p2040.
CU230-2P DP:
- set the PROFIBUS master to the RUN state.
- 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.
A01945 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, binary interpretation):
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.
