AKD BASIC Global Variables - Two Minutes of Motion Series

Transcript

Gordon S. Ritchie: (18.00)
Hello, I’m Gordon Ritchie with Kollmorgen and this is “Two Minutes of Motion”. In this video exercise we will be discussing how to declare a global variable to an entire program within AKD Basic. Global variables are specified as a means to be shared between main program functions and subroutines.
Gordon S. Ritchie: (25.25)
Variables are an important part of any program, AKD Basic allows for the definition of variables in many ways. When outlining variables for use in the programming environment, global variables are typically needed when all subroutines and functions need access to the specified variable. Global variable definition eliminates the need for them to be defined locally in subroutines and functions.
Gordon S. Ritchie: (22.44)
In our program, there are two variables defined: “Count” and “Caption”. “Count” is globally dimensioned as an integer and will be used in the main program area. “Caption” is a global string variable that will be included in a subroutine. Our program includes a “while…wend” loop where the motor will turn a relative distance of one revolution while 1=1.
Gordon S. Ritchie: (14.28)
Next our program calls our global variable to count each revolution performed by the motor in the “while…wend” loop. The value of our global Count variable is then printed to the console output and cleared after two seconds.
Gordon S. Ritchie: (25.65)
Our program then calls a subroutine named “StringOutput” that will utilize our globally defined string variable “Caption”. The purpose of this subroutine is to print the string value “Cycle Complete” before the “while….wend” loop of the main program begins another cycle. Since “Caption” is globally defined, this subroutine can access the variable to be displayed.
Gordon S. Ritchie: (18.54)
It is important to note that while Global Variables are shared within a program, they are not shared between programs. For more information, check out other Two Minutes of Motion segments, or sign up for one of our AKD Basic classes at: w w w Dot Kollmorgen Dot com.

Defining global variables is an easy way to share variable definitions throughout your main program, sub programs, and functions. It's easy to do in AKD BASIC as this video demonstrates.

AGV Sensors

AGVs operate by multiple sensors. The main sensor areas are: Navigation, Safety and Load handling.

AGV Safety

The first priority in AGV applications is safety!
Safety sensors have multiple safety fields. The main fields are stop field nd slow down field. The fields are configured by speed and steering angle.

What is an AGV?

AGVs & Mobile Robots handle logistics flows autonomously. They increase both efficiency and safety and are essential for Industry 4.0.

Where do I find AGVs and Mobile Robots?

AGVs & Mobile Robots operate in many different applications: manufacturing, logistics & warehousing, e-commerce, hospitals, parking and many more.

How does an AGV navigate?

AGVs & Mobile Robots navigate in different ways: natural, reflector, spot, magnetic tape, inductive wire, bar code or by combining technologies - multi-navigation.

What does an AGV system consist of?

An AGV system consists of three main elements: System, Vehicles and Tools

System – flow control, traffic control, integration
Vehicle – software, controller, sensors
Tools – design & service

Follow an order in an AGV system

The AGV system receives a transport order. The order is allocated to a vehicle, the load is picked up, transported to drop off position and dropped off. The order is finished and the vehicle is ready to receive a new order.
