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!

Arduino Uno Super Starter Kit Hardware


Arduino consists of a family of single programmable circuit boards and the IDE (Integrated Development Environment) that uses a streamlined version of C++ to write and upload code to the boards. Many pre-configured circuit boards, called “shields”, are available to expand the functionality of the Arduino controller. These shields can provide Ethernet, WiFi, GPS, LCD displays, and motor controls, among others, by simply “stacking” or connecting the shields to the Arduino controller board. This Lego-style building of electronic devices is becoming more popular.

The Arduino UNO is one of the best board to learn about electronics and coding. This robust board is the most used and documented board of the whole Arduino family.

P1AM Industrial Arduino P1000 Expansion Analog


We will now look at the P1AM Arduino expansion analog modules. This analog expansion is part of the P1000 cards that the P1AM Arduino can use as it’s inputs and outputs. The productivity open P1AM I/O interface chip-set supports the full suite of Productivity 1000 I/O expansion modules. These modules are industry approved and proven in the industrial environment. Modern industrial signal levels for digital and analog inputs and outputs are used.

Capacitive Pushbutton Sensor Switch /Indicator


We will now look at the capacitive pushbutton sensor switch and indicator.
Normal pushbuttons on a panel are usually a mechanical device. They can become “sticky” when too much dirt or oil is present. Capacitive push buttons do not have moving parts to stick, so the life expectancy is increased. Disinfectant sprays can be applied directly to a capacitive pushbutton and left to dry so it can be more effective for the safety of your operators.

capacitive pushbutton sensor switch

Captron pushbutton sensor switches use capacitive sensing to detect when a hand or body part nears the device surface; built-in or stand-alone indicators provide multi-color signaling options. The robust IP69K design provides wear-free operation, plus resistance to water, oil, and harsh environments. These PNP NO DC-operated devices are available in 22mm, 50mm, and 60mm mounting diameters. Construction materials include plastic and stainless steel, aluminum, or polycarbonate. The corresponding 22mm LED signal indicator lights are also IP69K rated and have a 20mm diameter illuminated area; green, red, yellow, white, orange, and magenta signal colors are available.
capacitive pushbutton sensor switch
We will be wiring a 22mm captron pushbutton to a click plc. Upon activating the sensor for half a second output on the click plc will turn on. The green LED on the captron will turn solid green. When the sensor is selected again, the output will turn off. The Green LED will then blink indicating that the output is off.
Let’s get started! Continue Reading!

Productivity 1000 PLC to Modbus TCP RTU BX-MBIO


We will now look at the productivity 1000 plc modbus tcp rtu communication to the BX-MBIO controller.
The Productivity 1000 PLC can communicate to a remote I/O (input and output) controller modules using the Modbus protocol for communications. The BX-MBIO provides both Modbus RTU and Modbus TCP interfaces. Modbus RTU is a serial communication and Modbus TCP is an Ethernet communication. Modbus RTU is supported over an RS-485 serial connection. Modbus TCP is supported over an Ethernet connection. They function as listening/replying devices (slave, server) and can connect with any mastering (master, client) device that communicates using the Modbus protocol.
Previously we looked at the BX-MBIO Modbus RTU TCP Remote IO Controller wiring and configuration.

Wiring 3 Wire DC NPN and PNP Sensors




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 attached to the blue wire and a load across the others, what does it all mean?
Wiring 3 Wire DC NPN and PNP Sensors
It is quite confusing sometimes the language we use for these devices. Sometimes it is the way we talk about the sensor and sometimes about the device we are connecting. (PLC)
We will break it down and go over the wiring to a PLC input. Let’s get started. Continue Reading!
