Accessing the Analog I/O Configuration Window

To access the Analog I/O configuration window, double-click MyController > Analog in the Devices tree.

Analog I/O Configuration Window

The following window allows you to configure the analog I/O:

NOTE: Embedded analog I/Os are always physically updated by the MAST task, same as expansion I/Os.

For more information on the Analog I/O Mapping tab, refer to the EcoStruxure Machine Expert Programming Guide.

Configuration Parameters

You can configure the following input parameters:

Parameter	Value	Description	Constraint
Type	Not used * – 10...10 V 0...10 V 0...20 mA 4...20 mA	Range mode	–
Scope	Normal Customized	Unit	Available if Type value is defined.
Filter Level	0 * to 6	Filter value reduces the effect of noise on a controller analog input	Available if Type value is defined.
Minimum	– 32768 to 32767⁽¹⁾	Minimum value	Available if Scope is customized.
Maximum	– 32768 to 32767⁽²⁾	Maximum value	Available if Scope is customized.
* parameter default value (1) If Scope is Normal and Type is – 10...10 V, the default value is -4096. If Scope is Customized, the default value is – 32768 . (2) If Scope is Normal, the default value is 4095 . If Scope is Customized, the default value is 32767.
