6.1 Alarms for SINUMERIK 840digital
Remedy Check the DP wiring. Restart F slave modules. Restart the NCK/PLC.
Program continuation Clear the alarm with the RESET key. Restart part program.
27252
PROFIsafe: Slave %1, sign-of-life error
Parameter %1 = DP slave address
Explanation The specified DP slave no longer communicates with the master. Stop D/E is
triggered.
Response Mode group not ready
Channel not ready
NC start inhibit in this channel
Interface signals are set
Alarm display
NC stop for alarm
A STOP D/E is initiated (this can be set using MD $MN_SPL_STOP_MODE)
on all of the axes with safety functionality.
Remedy Check the DP wiring. Restart F slave modules. Restart the NCK/PLC.
Program continuation Clear the alarm with the RESET key. Restart part program.
27253
PROFIsafe: Communication fault F master component %1, error
%2
Parameter %1 = faulty components (NCK/PLC)
%2 = fault/error detected
Explanation The F master signals a communications error between the NCK and PLC.
The cause of the error is indicated by error code %1;
- %1 = NCK: Link between PROFIsafe and SPL interface is interrupted.
- %1 = PLC: The PLC no longer executes the OB40 request.
- %1 = PLC-DPM: DP master is no longer in the OPERATE state.
Parameter %2 provides additional information about the reason for the error:
- %2 = 0: NCK-internal sequence error (refer to %1=NCK).
- %2 = 1,2,4: PLC processing of the OB40 not finished.
Response Mode group not ready
Channel not ready
NC start inhibit in this channel
Interface signals are set
Alarm display
NC stop for alarm
A STOP D/E is initiated (this can be set using MD $MN_SPL_STOP_MODE)
on all of the axes with safety functionality.
Remedy Extend the PROFIsafe cycle time via MD
$MN_PROFISAFE_IPO_TIME_RATIO.
Program continuation Clear the alarm with the RESET key. Restart part program.
27254
PROFIsafe: F module%1, error on channel %2; %3<ALSI>
Parameter %1 = PROFIsafe address
%2 = channel number
%3 = supplementary information system variables – field index
Explanation The F module signals that an error has occurred in the interface of the specified
channel.
