Accelerate Learning …
It is a good time to be in the automation business. 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.
2019 has been our best year yet thanks to you. Keep on Reading!
The C-More HMI Panel can log data using the Line Trend Graph or PID Faceplate Trend Graph objects. When Save Log Data is selected on the Options tab configuration for that object, data is written to a “.txt ” file saved to the storage device selected.
Data Logging is commonly used to monitor systems and/or processes taking place at an industrial facility, providing time, date, and current conditions as configured on the Object. Data Logging can be used to collect temperatures, flows, alarms, levels, pressure and just about any instrument measurable condition.
We will be data logging from a Line Trend Graph. A register (word) made up of bits will also be logged. We will log this information every second on our USB stick. Starting/stopping the logging can be controlled on the HMI as well as USB reject. Once the USB is ejected, it can then be connected to our computer to review the files. We will also view and download the files from our web server that we enabled last time on our C-More EA9 HMI panel. Let’s get started. Continue Reading!
MQTT stands for Message Queuing Telemetry Transport. This simple publish and subscribe communication protocol does not take too many resources.
Constrained devices with low bandwidth are ideal for MQTT. This protocol provides machine to machine (M2M) connectivity which is ideal for the Internet of Things. (IoT) This protocol is not for remote IO or real-time (deterministic) applications. MQTT is a good solution for applications that move data from hundreds or thousands of machines (sensors) to clients in many networks.
We will be installing a windows based broker called Mosquitto. The Do-More BRX PLC will be one of the clients publishing and subscribing to the MQTT broker. MQTT Lens (Chrome Browser App) will be the other client publishing and subscribing to the MQTT broker. Each client will share information. Let’s get started. Continue Reading!
The C-More HMI Panel can function as a simple web server. A web server includes software and hardware that will respond to World Wide Web client requests. The communication used between client and server takes place using the Hypertext Transfer Protocol. (HTTP). Information generally takes the form of pages that may include images, style sheets and scripts in addition to the page text contents. Remote access will allow for viewing or controlling the C-More EA9 HMI. We can use any windows based machine or use the C-More remote HMI App from Apple iTunes store, Google Play or Amazon App Store for mobile devices.
We will turn on the webserver functionality in our HMI panel. Using a web browser (Chrome), we will connect to our C-More EA9 HMI. We will then download the remote access software from the website. We will then run this remote access software to control our existing HMI program. Let’s get started. Continue Reading!

We will be using a free on-line public MQTT broker from HiveMQ. Messages will be published and subscribed to by two clients. The first will be an MQTT Browser Client by HiveMQ. The Do-More Designer Simulator PLC will be the second MQTT Client. Information in the form of bits and words will be published and sent to both clients. Let’s get started. Continue Reading!
