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.
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:
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.
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.
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.
