Watch

Overview

Watch allows viewing hundreds of Boolean, integer, and analog controller parameters (Sources) such as I/O, position, and torque (all Sources are also available in the Scope). Boolean values are colored uniquely: a 1 is green and a 0 is red. By double-clicking any of the digital outputs (@OUT), the output point can be toggled. The Watch window is divided into the tabs All and Some, which both contain dynamically updated status from the controller data record (QR).

Hint: Use the refresh button (F5) in the toolbar to refresh the connection if you change the configuration of AQ,DQ,TM,CO, and BA.

All

The data record Watch window. The All tab displays the entire controller Data Record, and allows access to customizing the data record to suit an application

On the All tab, each column can be sorted by clicking on the title header. For example, sorting by Description groups axis data together (_TPA, _RPA) and sorting by Source groups similar data together (_TPA, _TPB). When keyboard focus is within the Source column, entries can be looked up by typing the first few characters of their Source name.

Some

To monitor a subset of the All tab, select the desired Sources under the Some tab.
Monitoring a subset of the data record with Watch Some

Clicking in a row's Source cell provides access to a drop down list of all data record Sources. Choose one from the last row to create a new row. Right clicking in the value cell of any row allows that row to be Removed or another row to be Inserted.

The rows selected in the Watch Some are remembered in the GalilTools Project for the next launch. The active tab, All or Some, is also remember along with window position, size, etc.

User Units, Descritpion, Scale and Offset

Watch ALL is a listing of the controller's data record. GalilTools represents the data record as "sources". Sources are used in both the Watch and the Scope to provide information to the user regarding the controllers current state. A source has the following components.

Source - The static Galil name for the data, e.g. @IN[01]
Value - The current value of the source from the controller, post-processed by Scale and Offset
Units - The engineering units of the source. Galil recommends a units value, but the user can specify this by typing a new unit string in the units cell
Description - The human-readable description of the source. Galil recommends a description, but the user can change it by typing a new description string in the description cell
Scale - Used to scale the value returned from the controller. The scale is in effect a divisor. Raw values are divided by the scale value to provide post-processing for user display. A new value can be set in the value cell to provide application-specific scaling.
Offset - The offset bias to add to the raw value from the contoller to provide application specific post-processing of data

Scale and Offset operate on the controller's raw data record in the form of:

						Raw Value
				Source Value = ----------- + Offset
					  	  Scale

If Units, Description, Scale, or Offset are changed, these changes are also reflected in Watch Some and the Scope operation. Changes are persisted by the Galil Project through launches. To create a factory default version of the Galil data record sources, create a new project.
