Program Introduction

Description

The robot uses a timer to calculate the time taken from establishing the communication to completing picking and placing each time.

File path

You can navigate to the installation directory of Mech-Vision and Mech-Viz and find the file by using the Communication Component/Robot_Interface/ABB/sample/MM_S11_Viz_Timer path.

For RobotWare6, the file extension is .mod. For RobotWare7, please modify the file extension from .mod to .modx.

Project

Mech-Vision and Mech-Viz projects

Prerequisites

You have set up the standard interface communication.
Automatic calibration is completed.

This example program is provided for reference only. Before using the program, please modify the program according to the actual scenario.

Program Description

This part describes the MM_S11_Viz_Timer example program.

The only difference between the MM_S11_Viz_Timer example program and the MM_S2_Viz_Basic example program is that MM_S11_Viz_Timer can use a timer to calculate the required time (this code of this feature is bolded). As such, only the feature of using a timer to calculate the required time is described in the following section. For information about the parts of MM_S11_Viz_Timer that are consistent with those of MM_S2_Viz_Basic, see Example Program 2: MM_S2_Viz_Basic.

The workflow corresponding to the above example program code is shown in the figure below.

The table below describes the feature of using a timer to calculate the required time.

Feature Code and description

Feature	Code and description
Calculate the time taken from establishing the communication to completing picking and placing each time by looping	`LOOP: ... GOTO LOOP;` The above code indicates that the program loops through the code between LOOP and GOTO LOOP. `!reset timer to 0 ClkReset timer;` The above code resets the timer to 0. `!start timer ClkStart timer;` The above code starts running the timer. `!stop timer ClkStop timer;` The above code stops the timer. `timer_val:=ClkRead(timer);` In the above example, the ClkRead command reads the time calculated by the timer (i.e., the amount of time taken from establishing the communication to completing picking and placing each time) and then assigns the time value to the timer_val variable. `TPWrite "single cycle time: "+numtostr(timer_val,3)+"s.";` numtostr(timer_val,3): Convert the value of the timer_val variable (rounded to three decimal places) to a string. TPWrite: Display the corresponding string on the teach pendant screen. The entire statement displays the calculated time on the teach pendant screen.

Calculate the time taken from establishing the communication to completing picking and placing each time by looping

LOOP:
    ...
    GOTO LOOP;

The above code indicates that the program loops through the code between LOOP and GOTO LOOP.

!reset timer to 0
ClkReset timer;

The above code resets the timer to 0.

!start timer
ClkStart timer;

The above code starts running the timer.

!stop timer
ClkStop timer;

The above code stops the timer.

timer_val:=ClkRead(timer);

In the above example, the ClkRead command reads the time calculated by the timer (i.e., the amount of time taken from establishing the communication to completing picking and placing each time) and then assigns the time value to the timer_val variable.

TPWrite "single cycle time: "+numtostr(timer_val,3)+"s.";

numtostr(timer_val,3): Convert the value of the timer_val variable (rounded to three decimal places) to a string.
TPWrite: Display the corresponding string on the teach pendant screen.

The entire statement displays the calculated time on the teach pendant screen.
