Proximity (Capacitive, Inductive), Photo electric (Thru beam, Retro Reflective, Diffuse), Ultrasonic, etc. Sensors can be either discrete (On/Off) or Analog outputs.

PLC Learning Series – What are Outputs?


PLC outputs are the next component of our PLC block diagram. The outputs of the PLC will be controlled by the PLC program. Controlling outputs is one way to get the inputs to change. We will be looking at digital and analog outputs that can be wired to the programmable logic controller.
PLC Learning Series - What are Outputs?

PLC troubleshooting outputs will also be discussed. This will be done using a multimeter measuring voltage both at the PLC output and across the discrete output load. We will also measure and control an analog signal output. Let’s get started. Keep on Reading!

PLC Learning Series – What are Inputs?


PLC inputs are one component of our PLC block diagram. The output actions of the PLC will be controlled based on the inputs. We will be looking at digital and analog inputs that can be wired to the programmable logic controller.
PLC Learning Series - What are Inputs?
PLC Learning Series - What are Inputs?
We will be looking at wiring of a normally open (NO) push button, normally closed (NC) push button, 3 wire PNP sensor, and an analog sensor to the PLC. These will all be sinking inputs. Let’s get started. Keep on Reading!

Arduino Uno Super Starter Kit Ultrasonic Sensor


The ultrasonic sensor (HC-SR04) is great for all kinds of projects that need distance measurements. The HC-SR04 is inexpensive and easy to use. We will be sending signals directly to the sensor and interpreting the results without the need for a library.
Arduino Uno Super Starter Kit Ultrasonic Sensor
Ultrasonic sensor module HC-SR04 provides a 2cm-400cm non-contact measurement function, the accuracy can reach 3mm. The modules include ultrasonic transmitters, receivers, and control circuits. We will be wiring the ultrasonic sensor to our Arduino UNO R3 controller on our super starter kit. Let’s get started. Continue Reading!

ACC Automation 2020 Yearly Review
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!

Omron CP1H PLC to CMore HMI EA9 RHMI


The C-More EA9 Series of human-machine interfaces (HMI) provides a way for the operator to control and will perform a lot of additional items. The free programming software is very user friendly and fully featured. Here are some of the additional items that this robust and powerful HMI can do besides communicating to programmable logic controllers (PLCs).
Send Email – This includes authentication for the email client protocol
Log Data – This can log data files to the internal memory or an external thumb drive (32G)
FTP Server – Use file transfer protocol to retrieve information from the HMI to a network. This can be done automatically with a batch file.
Web Server – This HMI can be a web server on your network
Remote Internet Access – Windows, Android, and IOS operating systems have the ability to take advantage of this remote access to the HMI. The programs are free and fully functional.
omron plc to cmore hmi
Our sample CP1H PLC program will use buttons and indicators to control a start/stop jog circuit. An analog input into the PLC will be scaled and displayed on a gauge and numeric display on our HMI screen. We will also write information to our 7 segment display on the CPU from our HMI screen. Omron serial host link protocol will be used to communicate over an RS485 serial cable. We will demonstrate remote access using our windows and android device. Let’s get started. Continue Reading!
