AI with Measuring

The following sections show the properties of analog inputs (AI) with the subsystem-specific extension "Measuring". Analog inputs with the subsystem-specific extension "Measuring" are not supported in Desigo 5.x.

Channel configuration properties

The listed properties are displayed in the Hardware and network editor > Inspector window > Properties tab when the data point is selected in the Device view tab.

Number of channels
"Number of channels" defines how many channels are used by the data point. If more than one channel is used by the I/O data point, all properties are stored in the first channel.

Number of channels

"Number of channels" defines how many channels are used by the data point.

If more than one channel is used by the I/O data point, all properties are stored in the first channel.

COV limit
"COV limit" defines the change in the process value that triggers the sending of the process value. Range: 0...32767 (Standardized raw value)

"COV limit" defines the change in the process value that triggers the sending of the process value.

Range: 0...32767 (Standardized raw value)

Unit
"Unit" defines the physical unit of the input or the output.

Save as
"Save as" saves the set parameters of the I/O data point as an xml-file.

Subsystem-specific extension properties

The listed properties are displayed in the BACnet objects editor > Inspector window > Properties > Configuration tab when the data point is selected in the editor table.

✳ Indicates a Siemens proprietary property.

Supported signal types ✳
"Supported signal types" defines which signal types are supported by the hardware.

The signal type defined in the property "Signal type" has to be set to "True".

Signal type
'Signal type' defines the signal type for its I/O channel. The available signal types depend on the specific hardware, e.g. I/O module type or Onboard-I/O type.
Property ID: 4968

Process value 1 and Process value 2 ✳
"Signal value 1" (X1), "Signal value 2" (X2), "Process value 1" (Y1) and "Process value 2" (Y2) are used to calculate the linear function (f). The linear function is needed to calculate the present value out of the measured signal value. Unit: Depends on the process value. Range: -1 if the function needed to calculate the present value out of the measured signal value is completely defined by the selected signal type. Example: Ni1000 Any Value ≠-1 if the function needed to calculate the present value out of the measured signal value is not completely defined by the selected signal type.

Process value 1 and Process value 2 ✳

"Signal value 1" (X1), "Signal value 2" (X2), "Process value 1" (Y1) and "Process value 2" (Y2) are used to calculate the linear function (f). The linear function is needed to calculate the present value out of the measured signal value.

Unit: Depends on the process value.

Range:

-1 if the function needed to calculate the present value out of the measured signal value is completely defined by the selected signal type. Example: Ni1000

Any Value ≠-1 if the function needed to calculate the present value out of the measured signal value is not completely defined by the selected signal type.

Signal value 1 and Signal value 2 ✳
