Input/Output Status Text (prior to V2.04.xx)
2 status texts per digital data output Two status texts can be assigned to each digital datapoint status. Status texts give
an overview of the condition of the sensor or switching device connected to the
datapoint.
The associated status text appears in the attribute "Value" depending on the actual
point status.
For instance, the status texts could be as follows for a point connected to a digital
output:
Digital point status 0: Status Text: "Passive”
Digital point status 1: Status Text: "Active”

Input/Output Status
Active State (prior to V.2.04.x)
Status Text
0 0 active
0 1 passive
1 0 passive
1 1 active
Status Text with flexible datapoints The attribute "Status Text" allows you to describe the value sent to the controller by
the digital output Pulse 1 and by flexible datapoints. In the case of flexible
datapoints of the type "feedback", the status text refers to the value of the feedback
flexible datapoint and not to the required value.
Input/Output Status Text (V2.04.xx or higher)
With firmware 2.04.xx or higher, the relationship between physical output status and
logical output status as defined by the attribute "Normally Open/Normally Closed"
determines the display of the equivalent status text. See section "Normally
Open/Normally Closed (V2.04.xx or higher)" on page 28 for details.
Interval Count
Interval count The attribute "Interval Count" shows the totalizer value (pulse x scaling factor)
accumulated since the last reset.
Displaying the interval count The attribute "Interval Count" can be viewed on the XI581, XI582, and Excel 50 MMI
operating units as well as via the XL-Online Operating Software and building
Supervisor front-ends like XBS, EBI and XFI. Based on mathematical rounding, it is
