Parameters: %1 = TO unit %2 = Tool identifier (name) %3 = -Not used%4 = D number Definitions: Tool monitoring: This message informs that the spec ified D offset has reached its prewarning 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, t he duplo number specified has no meaning. The alarm is triggered through the HMI or PLC (=OPI interface). The channel context is not defined. The TO unit was specified for this reason (see MD28085 $MC_MM_LINK_TOA_UNIT). Reaction: Interface signals are set. Alarm display. Remedy: For information only. The user must decide what to do. Program Continuation: Clear alarm with the Delete key or NC START.
