I/O Summary

The I/O Summary is different from other Summary windows in two ways. First, the type of I/O objects that can be displayed are broken out into sub-types. Each sub-type is displayed in its own tab page. For example, there are tab pages for CAN I/O and Motor I/O. Secondly, unlike other Summary windows, objects are represented as rows and attributes are represented in columns.

 

Configuration Attributes: "SqNode I/O" Tab Page

This window displays a breakdown for SynqNet I/O. See MEISqNodeInfoIo.

Type – The SqNode I/O objects are sorted by type. Each type is color-coded. The table below describes the I/O types.

 
  • Digital Output (DO) – red
  • Analog Output (AO) – blue
  • Digital Input (DI) – yellow
  • Analog Input (AI) – green

Value – The Value attribute for an Input I/O object is read-only. For Digital I/O, the value is represented as a checkbox. Checked is HIGH, unchecked is LOW. The analog value is a 16-bit number that contains the raw bits going to/from the SynqNet node. The relationship between the 16-bit number and the analog value is described with the documentation for each analog module or slice. For example, the analog data for the ADC4DAC4 module has the following relationship:

7FFFh
+10V
8000h
–10V

For more information, please see Accessing Analog Data.

 

Configuration Attributes: "Motor I/O" Tab Page

This window displays the I/O associated with motor objects.

The number of I/O objects associated with a motor depends on the type of SynqNet Node that the motor is mapped to. If the motor is not mapped to a SynqNet Node, then it has no I/O. See Motor I/O for more information.

Type – The choices for the types of I/O depend on the type of SynqNet Node that the motor is mapped to.

Out – Value to write to the bit. Checked is HIGH, unchecked is LOW.

In – Value read from the bit.

 

Configuration Attributes: "CAN I/O" Tab Page

This window displays a breakdown of the I/O for a CAN system.

Type – The CAN I/O objects are sorted by type. Each type is color-coded. The table below describes the I/O types.

 
  • Digital Out (red) – Digital Output
  • Analog Out (blue) – Analog Output
  • Digital In (yellow) – Digital Input
  • Analog In (green) – Analog Input

Value – The Value attribute for an Input I/O object is read-only. For Digital I/O, the value is represented as a checkbox. Checked is HIGH, unchecked is LOW. For Analog I/O, the value is a floating point number normalized to be between -1 and 1.

 

Configuration Attributes: "Control I/O" Tab Page

This window displays the I/O associated with control objects.

Type – The Control I/O are sorted by type. Each type is color coded. The list below describes the I/O types.

 
  • Digital Out (red) – Digital Output
  • Digital In (yellow) – Digital Input

Value – The Value attribute for an Input I/O object is read-only. For Digital I/O, the value is represented as a checkbox. When checked, it's HIGH. When unchecked, it's LOW.
