Omron serial communication protocol. It is usually RS232, RS422 or RS485. This protocol is also called Sysmac Way.

ACC Automation 2020 Yearly Review

ACC Automation

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 to C-More Micro HMI Communication


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!

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.

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!

Omron CP1H AdvancedHMI Communication

We will now use AdvancedHMI to communicate to our Omron CP1H controller. Advanced HMI is a powerful, adaptable HMI/SCADA (Supervisory Control and Data Acquisition) development package that takes advantage of Visual Studio. There is no coding required and you can simply drag and drop items onto the page. The best thing is that the software is free. We will look at using AdvancedHMI with the Omron CP1H PLC.
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 on our AdvancedHMI screen. We will also write information to our 7 segment display on the CPU from our AdvancedHMI screen. This communication will be done using Omron serial host link protocol over an RS485 serial cable. The AdvancedHMI package will run on a windows PC and communicate out the port using a USB to RS485 adapter. Let’s get started. Continue Reading!
