Sinumerik Alarm 6412 TO unit %1 tool %2 / Duplo no. %3 has reached its monitoring limit with D = %4
%1 = TO unit
%2 = Tool identifier (name)
%3 = Duplo number
%4 = D number
Tool monitoring: This message informs that the specified D offset has reached its pre warning limit for a time-, quantity- or wear-monitored tool. If possible, the D number is displayed; if not, value 0 is assigned to the 4th parameter.
If the function additive offset is being used, additive offset monitoring may be active instead of tool wear monitoring.The actual type of tool monitoring is a tool property (see $TC TP9).
If replacement tools are not being used, the duplo number specified has no meaning. The alarm is triggered through the MMC or PLC (=OPI interface). The channel context is not defined. The TO unit was specified for this reason (see $MC_MM_LINK_TOA_UNIT).
