We will now be looking at LEDs that we can wire and program using our Arduino Uno super starter kit. Light-emitting diodes (LEDs) are semiconductor devices that will show light when current passes through them. This light is produced within the solid semiconductor material so it can be called a solid-state lighting device.
We will be looking at the wiring of LEDs with our breadboard. Different resistor values will be used to change the LED light brightness. We will discuss how we can calculate the amount of current passing through our LED.
An RGB LED and Red LED will then be wired to our Arduino UNO. The brightness and color of our LEDs will then be changed through the programming of the Arduino Uno. PWM outputs will be used in our program (sketch). Let’s get started. Continue Reading!
We will now look at the productivity Arduino Ethernet web server that we will implement on our Productivity Open P1AM industrial Arduino controller.
This P1AM Web Server Example is based on an example found here. This example uses the productivity open P1AM-ETH shield to create a web server that displays the input values of a P1-08SIM and P1-04THM to a web page. This page is automatically updated every 3 seconds. The IP address of the webserver is set in the Arduino program (Sketch) Entering this IP address in your browser to view the web page. This will display the information from our Arduino P1AM on our web browser. Let’s get started. Continue Reading!
We will now look at the BRX Do-More PLC Web Server. Ethernet equipped BRX CPUs and the Do-More Designer Simulator can now have a web server. This can be accessed by any web browser using the IP address of the BRX Do-More CPU.
A web server is server software or hardware dedicated to running this software, that can satisfy client requests on an Ethernet network. A web server can contain one or more websites and websites can have several web pages. A web server processes incoming network requests over HTTP and several other related protocols.
The website built into the BRX Do-More has several different tabs that have basic information about the system, status information like warnings and errors, input and outputs, system logs, user logs, and user pages. We will be enabling the webserver on our BRX Do-More PLC and showing the information that is available. This is a great tool for troubleshooting the PLC as you will see. Let’s get started.

What a difference a year makes! Social distancing, mask-wearing, hygiene, social circles, etc are just a few of the terms we hear every day in this Covid-19 world. Video conferencing with Zoom, Teams, and Google Meet are the norm in business today. Information is knowledge, and everyone wants to be able to see, control, and summarize production data on a regular basis. Technologies are merging and communicating like never before. What was impossible is now possible for the industrial plant floor. We are looking forward to the New Year and new possibilities for implementing your control solution.
Each year we like to take a few minutes and reflect on the past, current, and future of ACC Automation. You have helped us to build the site that you see today through questions, comments, and suggestions. Thank you. Keep on Reading!
We will now look at P1AM Arduino Modbus TCP communication to the C-More EA9 Series HMI. This will be communicating Ethernet Modbus TCP protocol. The P1AM will be the server (slave) and the EA9-RHMI the client (master).
We will explain how to connect a headless C-more HMI to our P1AM-ETH Industrial Arduino Ethernet Shield.
The P1AM Example from Automation Direct on GitHub will be used.
We will be using the remote android and windows app to connect to the C-More EA9 HMI. This will display the information from our Arduino P1AM on our headless unit. Let’s get started. Continue Reading!
We will now look at P1AM Arduino Modbus TCP communication to the C-More Micro EA3 HMI. This will be communicating the Ethernet Modbus TCP protocol. The P1AM will be the server (slave) and the EA3-T4CL the client (master).
There was a recent question on the Automation Direct Customer Forums that asked, “How do I connect an HMI C-more EA3-T4CL and P1AM PLC?“.
We will explain how to connect this to our P1AM-ETH Industrial Arduino Ethernet Shield.
The P1AM Example from Automation Direct on GitHub will be used.
We will be using the C-More Micro EA3-T4CL HMI that is posted. Let’s get started. Continue Reading!
The click plc has a real-time clock that will allow us to control outputs based on a date or time of day. This real-time clock (RTC) can be set from the click programming software or through the program of the controller. Our programs in the click can use the following calendar and clock values:
SD19 – RTC Year – 4 digits (2021)
SD20 – RTC Year – 2 digits (21)
SD21 – RTC Month – (00 to 12)
SD22 – RTC Day – (00 to 31)
SD23 – RTC Day of the Week – 1 Sunday to 7 Saturday
SD24 – RTC Hour – (00 to 23)
SD25 – RTC Minute – (00 to 59)
SD26 – RTC Second – (00 to 59)
We will be using the RTC – Real Time Clock in a sample program. This program will turn on an output Monday to Friday from noon until 1 pm. It will also adjust for daylight savings time. Let’s get started. Keep on Reading!
The C-More Micro HMI panel is a series of human-machine interfaces (HMI) that provide a way for the operator to control and view your programmable logic controller. (PLC) The free C-more microprogramming software is user friendly and fully featured. C-more Micro panels can easily display text, graphics, and bitmaps to effectively communicate critical data to your operator.
We will connect the EA3-T4CL cmore micro HMI screen to the Omron CP1H PLC. The devices will communicate serially via an RS485 interface. We will demonstrate reading and writing bits and words from the HMI unit. Let’s get started. Continue Reading!
The BRX Do-More PLC Peerlink Ethernet communication network is one of the easiest networks to set up and run. Peerlink is a shared programmable logic controller (PLC) common memory area within a local network. Do-More central processing units (CPUs) or DirectLogic PLC systems using ECOM100 modules can read the entire area and write to their programmed area if selected.
The network uses TCP/IP broadcast packets to publish the blocks of data PEERLINK (PL) memory to all of the devices attached. This broadcast will share the data network to the local domain only. Each member can optionally send data to the other members of the data-sharing network by electing to “publish” one or more blocks of PEERLINK (PL) memory.
This can sound confusing at first, but it is the simplest network to set up. You can have your Peerlink network up and running in a matter of minutes. We will be setting up and demonstrating the Peerlink network using a BRX BX-DM1E-18ED13 and the Do-More Simulator. Let’s get started. Continue Reading!
We will now install software to program our arduino uno. This arduino uno software is a free download and will operate on several operating systems. The IDE (Integrated Development Environment) software uses a streamlined version of C++ to write and upload code to the boards. This software is open-sourced and available free of charge. It will run on Windows, Mac, or Linux.
We will be installing the Arduino IDE on a Windows 7 machine. Connecting to our Arduino Uno, we will modify the blink program. (sketch) Let’s get started. Continue Reading!
