Channel %1 command %2 has invalid PLC acknowledge parameter %3 - identifier %4

%1 = Channel ID %2 = Command no.

%3 = PLC acknowledge parameter %4 = Error code

The specified command has been answered by PLC with an invalid acknowledgement in the current combination. 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 whether a buffer location for asynchronous tool motion must be reserved. 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. in tool motion command not end target

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    = it is not defined whether a buffer location for asynchronous tool motion must be reserved.

-    NC Start disable in this channel.

-    Interface signals are set.

-    Alarm display.

-    NC Stop on alarm.

Please inform the authorized personnel/service department. Erroneous PLC communication: Correct the PLC program.
