Configuration
4-49
• dynamically, depending on the particular event;
max. 16 characters.
Report
• If this field is checked, a message is triggered when the upper limit
value is exceeded.
Lower limit value
• If the measured value is lower than the lower limit value, a
message can be triggered.
• Further messages can only be triggered if the measured value has
risen above the upper limit value and has then again fallen below
the lower limit value.
Text for lower limit value
• A text that can be inserted into the message text using the text
block #VAL#; thus, it is possible to modify the message text
dynamically, depending on the particular event;
• Max. 16 characters.
Report
• If this field is checked, a message is triggered when the measured
value falls below the lower limit value.
Signalling when the measured value is lower/greater than a limit
value
• If the measured value falls below the lower limit value or exceeds
the upper limit value, a message is triggered.
• Further messages can only be triggered after the measured value
has fallen below or exceeded the corresponding other limit value.
Change
Signals when a measured value changes.
• A message can be triggered if a measured value changes by a
certain amount.
• The appropriate change is specified as a percentage and refers to
the measuring range of the input, e.g. voltage 0 ... 10 V; 10 %
corresponds to a change of 1 V.
If a measured value is monitored for changes, the debouncing time
is not considered, meaning that a message is triggered
immediately if the measured value changes accordingly.
