Subprograms: Action %2 Alnx Maximum Nesting Depth Exceeded; Caution: Program Test Modifies Tool Management Data - Siemens Sinamics S120 Diagnostic Manual

16922 [Channel %1: ] Subprograms: action %2<ALNX> maximum nesting depth exceeded
Parameters: %1 = Channel number
%2 = Action number/action name
Definitions: Various actions can cause the current procedure to be interrupted. Depending on the action, asynchronous subrou-
tines are activated. These asynchronous subroutines can be interrupted in the same manner as user programs. Unlim-
ited nesting depth is not possible for asynchronous subroutines due to memory limitations.
Example: An interrupt interrupts the current program processing. Other interrupts with higher priorities interrupt pro-
cessing of the previously activated asynchronous subroutines.
Possible actions are: DryRunOn/Off, DecodeSingleBlockOn, delete distance-to-go, interrupts .....
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Do not trigger the event on this block.
Program Clear alarm with the RESET key. Restart part program
Continuation:
16923 [Channel %1: ] Program control: action %2<ALNX> not allowed in the current state
Parameters: %1 = Channel number
%2 = Action number/action name
Definitions: The current processing cannot be stopped since a preprocessing process is active.
This applies, for example, to the loading of machine data, and in block searches until the search target is found.
Reaction: Interface signals are set.
Alarm display.
Remedy: Cancel by pressing RESET!
Program Clear alarm with the Delete key or NC START.
Continuation:
16924 [Channel %1: ] Caution: program test modifies tool management data
Parameters: %1 = Channel number
Definitions: Tool management data is changed during program testing. It is not possible to automatically rectify the data after ter-
mination of the program testing.
This error message prompts the user to make a backup copy of the data or to reimport the data after the operation is
terminated.
Reaction: Alarm display.
Remedy: Please inform the authorized personnel/service department.
Save tool data on HMI and reimport data after "ProgtestOff".
Program Clear alarm with the Delete key or NC START.
