Code 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 asynchronous tool motion. In the exam ple, 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. ar e 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 re jecting 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. Reaction: NC Start disable in this channel. Interface signals are set. Alarm display. NC Stop on alarm. Remedy: Please inform the authorized personnel/service dep artment. Erroneous PLC communication: Correct the PLC program. Program Continuation: Clear alarm with the RESET key. Restart part program
