Overview of Alarms
NCK alarms
27220 PROFIsafe: Number of NCK F modules (%1) <> Number of S7 F modules
(%2)
Parameters: %1 = Number of parameterized NCK F modules
%2 = Number of parameterized S7 F modules
Definitions: The number of F modules parameterized via the NCK machine data
$MN_PROFISAFE_IN/OUT_ADDRESS is:
- Greater than the number of PROFIBUS slaves in the S7 PROFIBUS configuration.
- Smaller than the number of F modules in the S7 PROFIBUS configuration,
- greater than the number of F modules known in the S7 PROFIBUS configuration.
If alarm parameter %2 = 0, then none of the configured F modules were found in the S7 PROFIBUS
configuration.
In most cases, the reason for the alarm is an error in the parameterization of the PROFIsafe master
address.
Reaction: Mode group not ready.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Check the F parameterization in MD $MN_PROFISAFE_IN/OUT_ADDRESS.
Check the F configuration in the S7 PROFIBUS configuration.
Check the parameterized PROFIsafe master address in MD
$MN_PROFISAFE_MASTER_ADDRESS and in the S7 PROFIBUS configuration.
Program Switch control OFF - ON.
Continuation:
27221 PROFIsafe: NCK F module MD %1[%2] unknown
Parameters: %1 = MD name
%2 = MD array index
Definitions: The F module parameterized in the specified machine data is unknown under this PROFIsafe address
in the S7 PROFIBUS configuration.
Reaction: Mode group not ready.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Check the PROFIsafe addresses in the NCK MD and S7 PROFIBUS configuration.
Program Switch control OFF - ON.
Continuation:
27222 PROFIsafe: S7 F module PROFIsafe address %1 unknown
Parameters: %1 = PROFIsafe address
Definitions: The F module with the specified PROFIsafe address has not been parameterized as an F module in
the NCK MD.
Reaction: Mode group not ready.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Check the S7 PROFIBUS configuration. Enter the module in the NCK MD.
Program Switch control OFF - ON.
Continuation:
