22 MonitoredParameterType ToC Previous Next

22.5 UpperTolerance, LowerTolerance, UpperTolerance2, LowerTolerance2, MinValue, MaxValue ToC Previous Next

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.

NOTE: When UpperTolerance and/or LowerTolerance are used, the SetValue shall be also given.

NOTE: When UpperTolerance2 and/or LowerTolerance2 are used, UpperTolerance and/or LowerTolerance shall be also given. UpperTolerance2 shall be between UpperTolerance and MaxValue. LowerTolerance2 shall be between LowerTolerance and MinValue.
