11.2 NCK safety alarms for SINUMERIK 840D sl

PROFIsafe: actual cycle time %1 [ms] > parameterized cycle time

%1 = actual PROFIsafe communications cycle time

The actual PROFIsafe communication cycle time is greater than the value set using MD10098 $MN_PRO‐

FISAFE_IPO_TIME_RATIO. The parameterized PROFIsafe communication cycle time is continually excee‐

ded on the PLC side.

Mode group not ready

NC start disable in this channel

Interface signals are set

Alarm display

NC stop for alarm

A STOP D/E is initiated (this can be set using MD10097 $MN_SAFE_SPL_STOP_MODE) on all axes with

safety functionality.

Adapt the cycle time using MD $MN_PROFISAFE_IPO_TIME_RATIO. As a minimum, the value displayed

in %1 must be set. The selected cycle time has an effect on the runtime utilization of the PLC module. This

must be taken into account in the setting.

Program con‐

Remove the error and press RESET

PROFIsafe: %1 %2 signals a system error %3 (%4)

%1 = communication type

%2 = PROFIsafe address or name of the F-module

%3 = error detection

%4 = component

A system error was detected within the scope of the PROFIsafe communication. Depending on the error, the

particular PROFIsafe driver is stopped or the complete PROFIsafe communication. The following displays

are possible for communication type (%1):

One of the following F-components (%2) can be involved:

- PROFIsafe address or the name of the F-module involved (for communication type = F-module)

- "-" (for communication type = SPL)

one of the following error causes is possible (see error ID %3):

- SF: Asynchronous fault state (StateFault)

- SP: The SPL input/output data are not updated (SPL I/O-communication)

The specified error IDs, depending on the error profile, can also be displayed in a combination. One of the

following components (%4) can be involved:
