27097 SPL start not executed
Definitions: SPL start not executed after predefined timeout in MD SAFE_SPL_START_TIMEOUT.
Reaction: Alarm display.
Remedy: Find the cause of the failure of the SPL to start. Possible causes may be:
- There is an NC or drive error (e.g. after encoder replacement, EMERGENCY STOP, PROFIsafe
alarms)
- There is a syntax error in the SPL
- Safety Integrated alarm present (e.g. "Safe limit position overrun")
- Name or path of SPL for PROG_EVENT Start written incorrectly; make sure upper and lower cases
are used correctly
- Simultaneous start of an ASUB and PROG_EVENT, parameterization MD 11602 (stop causes e.g.
read-in disable)
- Problems when calling FB4/FC9
This alarm can be masked via MD $MN_SAFE_DIAGNOSIS_MASK, Bit 1 = 1.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
27098 SPL commissioning phase terminated
Definitions: The SPL commissioning phase has just been terminated by changing MD
$MN_PREVENT_SYNACT_LOCK. After the next Power ON, file /_N_CST_DIR/_N_SAFE_SPF is
subject to the monitoring mechanisms defined for the SPL (access protection, checksum calculation).
Changes to the SPL can only be made in the unprotected mode.
Reaction: Alarm display.
Remedy: Perform a control Power ON. Check and document any changes to the logic in the SPL by means of
an acceptance test.
Program Con- Switch control OFF - ON.
tinuation:
27099 Double assignment in SPL assignment MD %1[%2] - MD %3[%4]
Parameters: %1 = MD name 1
%2 = MD array index for MD name 1
%3 = MD name 2
%4 = MD array index for MD name 2
Definitions: Different applications have double assigned SPL inputs ($A_INSE) in the displayed machine data.
These could be:
- PROFIsafe communication
- F_DP communication
Possible values for alarm parameters %1 and %3:
- $MN_PROFISAFE_IN_ASSIGN
- $MN_SAFE_RDP_ASSIGN
Reaction: Alarm display.
Remedy: Correct the MD.
Program Con- Switch control OFF - ON.
tinuation:
27100 At least one axis is not safely referenced
Definitions: There are two reasons for this alarm:
- the machine position of at least one of the axes monitored with SI has not yet been acknowledged
by the user, or
- the machine position of at least one of the axes monitored with SI has not yet been verified through
follow-up referencing.
Even if the axis is already referenced, there is no confirmation that referencing has supplied the cor-
rect result. For example, wrong results can occur if the axis was moved after the control was switched
off, with the result that the standstill position saved prior to switching off is no longer correct. To make
sure that this does not happen, the user must acknowledge the displayed actual position after the first
referencing process.
