The P1AM-GPIO is an industrial rated shield for the P1AM-100 Arduino system. It provides a connection from most of the P1AM-100 GPIO pins to the front 18 position terminal block connector.
We will be looking at the wiring and programming of this input and output industrial rated shield that mounts on the left side of the P1AM-100 CPU arduino unit.
Analog points will be wired to a potentiometer and LED (light-emitting diode) for demonstration of the voltage range that we can input and output. Digital points will be wired for discrete input and output using a pushbutton switch and LED. PWM (pulse width modulation) will also be used to control the brightness of a LED connected to a digital output. Let’s get started. Continue Reading!

Productivity Open P1AM Industrial Arduino Variables Data Types
Data types in the C++ language are used to determine the variable or function applied for the given type. The type will determine the size of the storage (bits), and the method to interpret the information.
Microprocessors can only understand binary (on / off) numbering systems. The interpretation of these binary numbers will allow us to have several different data types. We will be reviewing the different data types that we can use in our sketches (programs) for our P1AM-100 arduino industrial controller. Only the variables data types available in ProductivityBlocks will be discussed, but references will be made for all data types that can be used. We will then look at a program that will list some integer and string variables. This will then be displayed on the serial monitor of the Arduino IDE. Let’s get started. Continue Reading!
Productivity Open P1AM Industrial Arduino Program Structure
The P1AM-100 industrial controller is programmed with the Arduino IDE (Integrated Development Environment). The arduino IDE will allow us to write sketches (programs). These sketches have basic common elements like setup and loop.
We will be looking at these elements in our first program in the Arduino IDE and ProductivityBlocks. We will be modifying our first program with the selector switch. When it is on we will flash the CPU LED light on and off. When it is off we will ensure that the CPU LED light is off. Let’s get started.
Productivity Open P1AM Industrial Arduino First Program
The P1AM-100 industrial controller is programmed with the Arduino IDE (Integrated Development Environment). We installed the Arduino IDE, P1AM-100 library and ProductivityBlocks. Using this software we will be setting it up to program our P1AM Arduino industrial controller.
The Boards Manager will be used to set up our P1AM-100 Arduino board. We will then ensure that our device driver has been installed so we can communicate to the Productivity Open Controller. Using ProductivityBlocks, we will call up one of the sample programs, verify and upload the program to the P1AM-100. This program will blink the CPU LED light on and off. Let’s get started.
