Block %2 Inconsistent Data Modification Is Not Permitted; Writing Of $P_Usekt Not Allowed; Function Not Executable. No Tool Assigned To Desired Magazine - Siemens Sinamics S120 Diagnostic Manual

6438 [Channel %1: ] Block %2 inconsistent data modification is not permitted.
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: In a defined multitool, for example, the distance coding $TC_MTP_KD cannot be changed once the multitool location
has been generated.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Correct the NC program
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
6441

Writing of $P_USEKT not allowed.

Definitions: An attempt was made to write the value of $P_USEKT. This is not possible since programming T= 'location number'
with automatic setting of $P_USEKT is active.
Reaction: Interpreter stop
NC Start disable in this channel.
Interface signals are set.
Alarm display.
Remedy: - Check how the NC is supposed to be configured. (See bit16 and bit22 in MD 20310
$MC_TOOL_MANAGEMENT_MASK).
- Is a part program being used that is intended for an NC control without T='location number' with automatic setting of
$P_USEKT? This program cannot be started on an NC control with T='location number' with automatic setting of
$P_USEKT.
- Either run the part program on an appropriate NC control or edit the part program.
Program Clear alarm with the Delete key or NC START.
Continuation:
6442 [Channel %1: ] Function not executable. No tool assigned to desired magazine/
magazine location %2.
Parameters: %1 = Channel ID
%2 = Magazine/magazine location no.
Definitions: PLC logic is presumably incorrect. Tool change with reject tool is configured. Preparatory command is pending.
Selected tool is (e.g. from PLC) unloaded from its location. PLC acknowledges preparatory command with 'Repeat
tool selection' (e.g. status =7). NCK cannot find the tool at the magazine location specified in the PLC command.
Or: Illegal operator intervention in an active tool selection (unloading of the tool to be selected) has occurred. Therefore
the PLC acknowledgement fails.
Reaction: Interface signals are set.
Alarm display.
Remedy: PLC programmer must note the following:
- Ensure that the tool is not removed from the specified magazine location (e.g. incorrect PLC program).
- Do not remove the tool from the programmed tool change before the final acknowledgement of the command (=
unload).
!! It is however permissible to change the location of the tool to be loaded. The NCK can deal with this situation.
This alarm supplements Alarm 6405, if it contains the identifier 8. Therefore, the diagnostics should be easier.
Program Clear alarm with the Delete key or NC START.
