Look up the Current Word and Display its Value
This powerful function displays the definition of the word at the cursor. If the word has
some value, then that value is displayed and an option presented to change that value.
If the cursor is located on a Task name, the current State of the Task is displayed, and an
option to change the current State is offered. If the cursor is on an I/O name, the definition is displayed, and from the window the current value can be forced to another value.
Similarly, variable definitions are displayed and options presented to change those values.
Current State of Each Task
This function displays the active State of every Task. The display is updated twice per
second providing a realistic view of the current status of the process. Each Task name is
displayed, followed by its current State.
View Event Queue
The Event Queue includes time stamped data about the Controller such as Run, Halt,
Power Up, Power Down, Critical Run–T ime Errors, etc. The user may view up to the
last 64 entries with 6 being the default number to view.
View System Status
This includes system date, time, memory usage and current scan rates in milliseconds.
The scan rate information specifies the average scan rates for the last 1000 scans. The
scan is also split into the time for State Logic to be scanned and the time for the transfer
of I/O data between the SLP and CPU.
Trace
The Trace is a collection of the most recent program State transitions. This option allows
the user to display the history of State transitions on the screen for all Tasks or selected
Tasks.
Upload Trace from the Controller
This function will upload the Trace data from the controller and display it for the user to
browse through. The Trace is also stored in a file on the logged disk and directory so
that it may be viewed at a later time. Each upload of the Trace information, overwrites
the previous upload saved to disk. The Trace is stored in a file with the project name and
a .TRC extension, for example: CONVEYOR.TRC.
The display shows each State transition, listing the starting State, the resulting State and
the time of the transition. The most recent transition is at the top of the list.
There are string search functions available to help find a specific State transition. Press
<ALT + F> to access these search functions. Also the up and down arrows and <Pg
Up> and <Pg Dn> keys are used to move through the listing.
Display the Previously Uploaded Trace
This function reads and displays the file of the previous Trace display which is stored on
disk.
