A specific alarm message can be programmed for each of the system variables on the
HMI via parameter %3:
• %3 = 1....64: Error in system variables $A_INSE[1...64]
• %3 = 65...128: Error in system variables $A_OUTSE[1...64]
Reactions: - Mode group not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Trigger a STOP D/E (settable via MD $MN_SPL_STOP_MODE) on all axes with safety
functionality.
Remedy: Check wiring. Wiring OK: replace F module.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
27255
PROFIsafe: F module %1, general error
Parameters: %1 = PROFIsafe address
Definitions: The specified PROFIsafe module signals an error. A more exact specification of the
error's cause cannot be made without further assistance.
This alarm is triggered for all types of PROFIsafe slaves.
With ET200S F modules, this error can only occur if there already is a channel error when
the cyclical communication between the F master and module is begun.
Reactions: - Mode group not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Trigger a STOP D/E (settable via MD $MN_SPL_STOP_MODE) on all axes with safety
functionality.
Remedy: Check wiring.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
27256
PROFIsafe: Current cycle time %1 [ms]> parameterized cycle time
Parameters: %1 = Current PROFIsafe communication cycle time
Definitions: The current PROFIsafe communication cycle time is greater than the value set via MD
$MN_PROFISAFE_IPO_TIME_RATIO. The parameterized PROFIsafe communication
cycle time is continually exceeded on the PLC side.
Reactions: - Mode group not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Trigger a STOP D/E (settable via MD $MN_SPL_STOP_MODE) on all axes with safety
functionality.
Remedy: Adapt cycle time via MD $MN_PROFISAFE_IPO_TIME_RATIO.
The value displayed in parameter %1 has to be set at least.
The set cycle time affects the runtime load of the PLC module. This also has to be taken
into consideration when making the setting.
Program Con- Clear alarm with the RESET key. Restart part program
