<strong>11</strong>.03 3 Variables3.3 State data of system3.3.2 Area N, Mod. SALA: Alarms: List organized according to time,oldest alarm appears firstOEM-MMC: Linkitem/Nck/SequencedAlarms/...The NCK alarms are sorted in a list in the order they occurred, the oldest alarmappears at the top of the list. The alarm parameters are transferred as ASCIIstrings, the first character contains the type information for that parameter. Thefollowing types are used:S: General string, e.g. part program nameA: Axis name / spindle nameK: Channel nameN: Block numberY: System errorD: Drive numberIf a parameters is not assigned, an "S" is transferred.All variables in this module are privileged variables! This means that cyclicacknowledgements are sent for these variables even if the cyclic services areno longer serviced by the NCK because of block cycle problems.Attention: Privileged variables lose this characteristic if they are combined withnon-privileged variables in a request. -> Do not combine alarm variables withother variables in a cluster!In addition it is presumed that the cyclic services are set "on change" for thealarm variables and are not combined with other variables (not even withprivileged variables) in the same request.The module SALA only contains the alarms that are generated in the NCK. Itcontains neither PLC nor MMC alarms. In order to read all alarms, the OEM-MMC user should use the alarm server functions and not read the SALAmodule directly.alarmNoOrdinal number of an alarm (how many alarms since control ON)0 = unknown alarm- Long IntegerMulti-line: yesAlarm list index16The maximum alarm list index canbe read via variable numAlarms inmodule S.DAclearInfoAcknowledgement criteria for an alarm1 = Power On2 = Reset3 = Cancel4 = Alarm is cancelled by NCK-software (from SW 4.1)5 = Alarm is cancelled by starting a program6 = Alarm is cancelled by RESET in all channels of the bags (from SW 4.1)7 = Alarm is cancelled by RESET in all channels of the NC (from SW 4.1)- Long IntegerMulti-line: no 1DA© Siemens AG, <strong>2003</strong>.
