Principle of operation – extended alarm text
If Alarm 27090 or Alarm 27254 occurs, the NCK transfers an additional parameter
value to the HMI software (27090: %4; 27254: %3). This parameter has a defined
value range. Each value can be uniquely assigned an extended alarm text.

Parameterizing error detected when booting (different state active)
Crosswise data comparison error, SPL protective mechanism: MD 11500 –

Crosswise data comparison error, stop response for SPL error: MD 10097 –
DB18.DBX36.1
001...064
Error in system variables $A_INSE(P)[01...64] (Alarm 27090/Alarm 27254)
The index value then results from a channel error signaled from the PROFIsafe
module
(Alarm 27254), that is assigned the appropriate $A_INSE(P) variable (e.g. discrep-
ancy error)
065...128
Error in the system variables $A_OUTSE(P)[01...64] (Alarm 27090/Alarm 27254).
This means, Alarm 27090 signals an internal logic error ($A_OUTSE(P) variables
differ) and Alarm 27254 signals a channel error signaled from the PROFIsafe mod-
ule that is assigned to the appropriate $A_OUTSE(P) variable (e.g. short-circuit
fault).
129...192
Error in system variables $A_INSI(P)[01...64] (only alarm 27090)
193...256
Error in system variables $A_OUTSI(P)[01...64] (only alarm 27090)
257...320
Error in system variables $A_MARKERSI(P)[01...64] (only alarm 27090)
