Sub–range 2 can be used to analyze the active alarm responses.
Sub–range 1 can only be read or written as a double word. Sub–range 2 can only be read.
You can delete self–clearing alarms by resetting the respective bit in the variable range
''1600xxxx'' in sub–range 0 (1 –> 0 edge).
The remaining user alarms are cleared by the PLC after detecting the respective cancel condi-
tion. If the alarm is still present, the alarm occurs again.
