[Channel %1:] Tool Change Not Possible. Magazine No. %2 Not Available; [Channel %1: ] Plc Acknowledge For Command %2 Is Missing - Siemens Sinamics S120 Diagnostic Manual

NCK alarms
6405 [Channel %1: ] Command %2 has invalid PLC acknowledge parameter %3 - identifier
%4
Parameters: %1 = Channel ID
%2 = Command no.
%3 = PLC acknowledge parameter
%4 = Error code
Definitions: The specified command has been answered by the PLC with an invalid acknowledgement in the current context. The
following assignments are defined for "command no.":
1 Move tool, load or unload magazine
2 Prepare tool change
3 Execute tool change
4 Prepare tool change and execute with T command
5 Prepare tool change and execute with M command
7 Terminate canceled tool command
8 Check tool movement with reservation
9 Check tool movement
0 Transport acknowledgement
Parameters 2 and 3 designate the PLC command and the status number of the acknowledgement.
Example: Parameter 4 of the alarm message is 10. It is not defined that a buffer location has to be reserved for asyn-
chronous tool motion. In the example, the parameter is ignored by the NCK. Further possible causes for the alarm:
The tool change defined by the command is not possible. The magazine location specified in the invalid parameter
does not exist in the magazine.
The 3rd parameter - error identification - gives a more detailed description of the alarm. Meanings:
- 0 = not defined
- 1 = status not allowed or undefined status received by PLC
- 2 = source and/or target magazine no./location no. unknown
- 3 = not defined
- 4 = target magazine no. and/or location no. are not the end target in the tool motion command
- 5 = not defined
- 6 = source and/or target magazine no./location no. unknown during tool change
- 7 = PLC comm. with inconsistent data: either inconsistent magazine addresses in VDI or NCK command unequal to
PLC acknowledgement or both
- 8 = PLC comm. with inconsistent data: while rejecting a tool, the tool to be rejected was unloaded asynchronously.
NCK cannot perform a new selection.
- 9 = PLC comm. with inconsistent data: the command acknowledgement data wants to move a tool to a location that
is occupied by another tool.
- 10 = Asynchronous tool motion with reservation is only defined for the motion from a magazine to a buffer location.
