DAPL System Commands
DAPL includes over 100 built-in commands in the following categories. |
|---|
HELP- Commands the Data Acquisition Processor to send a list of all currently valid commands.
BDOWNLOAD (parameters, program)- Installs a program (binary data) from the host PC as a custom DAPL command.
DOWNLOAD (parameters, program)DAPL 4 Only- Installs a program (text data) from the host PC as a custom DAPL command.
OPTION (parameters)- Sets system options.
START (parameters)- Starts data input, output, or data processing.
STOP (parameters)- Stops data input, output, or data processing.
RESET- Resets system, retaining DAPL status.
RESTART- Restarts system, clearing DAPL status.
FILL (d, data)- Fills destination d with data from the host PC.
DIAGNOSTIC- Runs built-in hardware testing routines on the DAP. Returns a diagnostic code to the PC.
DISPLAY p- Displays configuration information. Parameter p specifies the type of information to display, including: available commands, pipes, variables, running tasks, memory use, triggers, configuration options, sampling status, and error history.
EDIT (parameters)- Modifies a previously defined input procedure, output procedure, or com pipe. Mainly used to reconfigure inputs, and outputs with new SET commands, and to change sampling and update rates with new TIME commands.
ERASE l- Erases the user-defined symbol represented by the label l.
HELLO- Displays DAP hardware and software model, serial, and version numbers.
LET l = n- Changes the value of the variable or constant represented by the label l to a new value n.
PAUSE n- Causes DAPL to pause for n milliseconds.
TASKSTAT STATUS- Displays a table showing CPU time on the DAP used by each running task. It also provides information about onboard CPU utilization, and the average task latency.
STATISTICS (ON | OFF | DISPLAY | CLEAR)- Starts, stops, displays or resets the system statistics collection. The collected information currently includes what command
TASKSTATdisplays plus the total elapsed time and the longest task cycle latency since the start or the last reset of collection. The command parameterDISPLAYis optional.
