Parameters: %1 = Channel ID %2 = String (identifier) %3 = -Not used%4 = Magazine number Definitions: The tool cannot be moved into the selected tool magazine. There is no appropriate location for this tool. A suitable location is mainly determined by the st atus. The status must indicate that this location is free, not disabled, not reserved and not co-occupied by a tool that is too large. Furthermore, it is important that the type of tool matches the type of any magazine location that may be free. (If, for example, all magazine locations are of the 'B' type and these are all free and the tool is of type 'A', then this tool cannot be put into this magazine). Reaction: NC Start disable in this channel. Interface signals are set. Alarm display. NC Stop on alarm. Remedy: - Check whether the magazine data have been defined correctly. - Check whether there is still room in the magaz ine to add another tool; there may not be due to operating procedures. - Check whether a location type hierarchy is defined and whether it, for example, does not allow insertion of a type 'A' tool in a free location with type 'B'. Program Continuation: Clear alarm with the RESET key. Restart part program
