代码 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) unl oaded 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 se lection (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. Therefor e, the diagnostics should be easier. Program Continuation: Clear alarm with the Delete key or NC START.
