Parameters: %1 = TO unit %2 = Tool identifier %3 = -Not usedDefinitions: The alarm can only occur when the tool management f unction is active in the NCK. Either the language command SETTA has been programmed or the corresponding operator action has been carried out via MMC, PLC,.... The alarm can also be tr iggered automatically by the NCK in the wear grouping function. It is detected that more than one tool from the tool group (tools with the same name/identifier) has the status "active". The specified tool is either from a non-considered magazine, from a non-considered wear grouping, or from a non-active wear grouping in a buffer location (is neither magazine nor wear grouping). Reaction: Interface signals are set. Alarm display. Remedy: The alarm is intended for information purposes. If only one tool in a group can be active at a time for technological reasons or for reasons of display, the "active" status must be canceled for the tool causing the error. Otherwise, the alarm can be ignored or even suppressed via the MD11410 $MN_SUPPRESS_ALARM_MASK. Typical reasons of display are present, if the oper ator works with the function 'definite D numbers', which can be displayed on Siemens MMC in a definite form only, if exactly one tool from a tool group has the status 'active'. Before machining can be started or before t he SETTA (or corresponding MMC operation,...) language command is used, all tools of the magazine should have the status "not active". One option to achieve this is programmi ng SETTIA (or corresponding MMC operation,...). Program Continuation: Clear alarm with the Delete key or NC START.
