ACC Automation: PLC & Industrial Control Learning
Practical Tips and Techniques
We will now look at logging data with time and date in the Click PLC. The Click PLC can perform indirect addressing. This means that I can ask for information to be moved to and from locations in the PLC using a pointer that will indicate the address. Stephen Covey in The 7 Habits of … Read more
Remote access will allow for viewing or controlling the C-More EA9 HMI series. 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. This software is available free of charge. Setting up the EA9 series for remote access … Read more
Wiring 3 wire DC sensors can be confusing. I recently received a question on PNP and NPN sensors. They wanted an explanation of what a sink is and how to wire one. Confusion over the Normally Open and Normally Closed function of the sensor is also a common question. Several diagrams will show a resistor … Read more
The C-more headless EA9-RHMI is programmed using the C-more Programming Software, EA9-PGMSW. The developed project is transferred from the PC to the HMI by either a USB or an Ethernet connection between the two. Previously we used the Ethernet connection to establish communication. We will be using the USB connection to establish communication, save the … Read more
The C-More EA9 HMI Panel through the Ethernet port can send secure email messages. These mail messages with attachments can be sent through a specified mail server. We will be sending an email using a Gmail account with authentication. This will also include an attached logged data file. We will also discuss how the C-More … Read more
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 … Read more
The C-More HMI Panel will support a barcode scanner (barcode reader) input. A scanner uses a light source and a light sensor to translate optical impulses into an electrical signal. The CMore can accept a USB barcode scanner input. We will now connect and program a barcode scanner into our HMI panel. The PLC ladder … Read more
We will now look at the C-More real-time clock object. The C-More HMI Panel software uses virtual components called Objects. These objects are programmable to simulate the functions that you require on your automation project. Pushbuttons, Switches, meters, and graphs are just a few of the objects that are available to you. The Clock Objects … Read more
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 … Read more
The C-More HMI Panel software uses virtual components called Objects. These objects are programmable to simulate the functions that you require on your automation project. Pushbuttons, Switches, meters, and graphs are just a few of the objects that are available to you. The Text List Objects include a variety of options to customize the display … Read more
