22.5 UpperTolerance, LowerTolerance, UpperTolerance2, LowerTolerance2, MinValue, MaxValue

These parameters are used to define limits for the monitored parameter. Exceeding the (relative) tolerance values creates a warning while exceeding the (absolute) Min/MaxValues leads to an alarm from type MonitoredParameterAlarmType and/or perhaps other actions on the machine (e.g. switching off the heating, stopping of movements) as defined by the severity level. With UpperTolerance2 and LowerTolerance2 a second tolerance band can be defined.
