Productivity P1AM Industrial Arduino PID Control


A Proportional-Integral-Derivative algorithm is a generic Control Loop feedback formula widely used in industrial control systems. A PID algorithm attempts to correct the error between a measured process variable and the desired setpoint by calculating and then outputting a corrective action that can adjust the process accordingly and rapidly, to keep the Error to a minimum.

We will be using an immersion heater in a cup of water to keep the temperature at a constant value.

Our immersion heater will be controlled through a relay using time proportional control from our PID output. A J type thermocouple will be used with the P1-04THM thermocouple temperature and voltage input module.

P1AM Industrial Arduino Watchdog Timer


A watchdog is a piece of code that will timeout when an error occurs in our program. It will usually cause the CPU (program/sketch) to stop or reset.

Productivity Open P1AM Arduino Time Instructions


Time instructions in our productivity blocks programming (Arduino sketches) consist of runtime (ms), runtime (us), delay ms, and delay microseconds us.
arduino time instructions
We will be looking at each of these instructions that are available for our program using productivity blocks. Delay instructions in our sketches should be used with caution. They will pause our program for the delayed time, not allowing other parts of the program to function. We will be looking at this and the method to do the exact same delay functions without pausing your program.

A sample program will be discussed to demonstrate the time functions in our program. Let’s get started. Continue Reading!

Productivity Open P1AM Industrial Arduino Math


Math instructions in your Arduino sketches (programs) consist of arithmetic operations, compound operators, absolute, power, square root, sin, cos, tan, random, map and constrain.

P1AM Industrial Arduino GPIO Inputs and Outputs


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.

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 Arduino Operators


Operators in your Arduino sketches (programs) consist of comparison blocks, concatenate strings, bitwise operators, string conversion, ‘not’ operator, and compound operators. These operations generally will be used with other instructions in your sketch. It is important to understand what instructions are available and what they are designed to accomplish.
Productivity Open P1AM Arduino Operators
We will be looking at each of these instructions that are available using productivity blocks. A sample sketch will be shown that will use some of these operators. The sketch will get a number between 1 and 100 from the built-in Arduino IDE (integrated development environment) serial monitor. It will print the number on the monitor if it is between 1 and 100, else it will print try again. Let’s get started! Continue Reading!

Productivity Open P1AM Arduino Program Control

Arduino programs (sketches) can be written in thousands of different ways. The best Arduino program control will be determined by the purpose of your program and what you are trying to accomplish. To simplify the logic we will be looking at program control that can be achieved using productivity blocks.
Program control will look at subroutines (sometimes referred to as methods or functions), conditional statements, and looping statements. These three items can be combined to reduce your code length, make your program easier to read, and in turn easier to troubleshoot.

Productivity Open P1AM Arduino Serial Monitor COM

We will now look at the Arduino serial monitor com. This serial communication is good for troubleshooting and displaying information to you or your operators. The Arduino integrated development environment (IDE) has a built-in pop-up serial monitor. The serial monitor can be used to receive and send serial data to our Arduino program. This can be a great feature to help us in debugging or controlling Arduino programs. (Sketches)
We will be modifying the blinking light program that we did previously and add a one to an integer every time the P1AM-100 arduino CPU switch is on. This will be then printed on the serial monitor.

Removing the blinking light, we will run our program again an see the difference in speed with the delay instructions removed. Productivity blocks will be used to program our industrial arduino controller.
We will then look at escape character codes that we can use with our industrial arduino. Since the built-in serial monitor will not interpret the escape codes, we will be using Putty as our serial monitor program. Let’s get started. Continue Reading!
