ACC Automation: PLC & Industrial Control Learning
Practical Tips and Techniques
This offers ways in which you can learn PLC programming.
Firmware is usually PLC operating system code that is written into a read-only memory. The BIOS (Basic Input Output System) of a PC (personal computer) is a good example of firmware. It provides a low-level interface between the hardware and software. The firmware for the productivity series of PLCs must be downloaded separately from the … Read more
The Ethernet Click PLC high-speed counter has seven different modes of operation. In Part 1 we discussed the High Speed Count Mode, Interval Measurement Mode, Duration Measurement Mode and Frequency Measurement Mode. This 100 kHz counter can accept Up, Down, Up/Down, Pulse/Direction, or Quadrature (with Z) inputs. We will be looking at the last three … Read more
The Click PLC family has been updated, and now has the ability to use high speed counting. This is available on all of the Ethernet units that have DC inputs. The faster processor on the Ethernet unit (3 to 10 times faster than the basic unit) allows this capability. There are seven (7) different modes … Read more
We will now look at the programming and wiring of a rotary encoder to the Click PLC input. Rotary encoders are modern digital devices that have taken over from the potentiometer in stereos and many other applications. This is because of their fine digital control, and they can fully rotate without end stops. We can … Read more
We would like to take a few minutes and reflect on the past, current and future of ACC Automation. Your questions, comments and suggestions have helped us to build the site that you see today. Thank you. YouTube Channel : ACC Automation https://youtu.be/nPa1aBQ_Rro 2018 has been our best year yet thanks to you.

The productivity series of PLCs comes with 4 built-in communication ports for easy connectivity to your PC or various industrial networks. Ethernet protocols like Modbus TCP can be utilized with the RJ45 port on this PLC. Modbus TCP is an open (published) protocol that uses the Server (Master) / Client (Slave) architecture. It’s a very … Read more
The productivity series of PLCs comes with 4 built-in communication ports for easy connectivity to your PC or various industrial networks. Serial protocols like Modbus RTU can be utilized with either the RS232 or RS485 ports on this PLC. Modbus RTU is an open (published) protocol that uses the Master / Slave architecture. It’s a … Read more
The productivity series of PLCs has a built-in web server. This web server function can make a non-secure (HTTP) connection to the CPU. This is done with your browser. You can then view read-only system tags and open, save or delete files stored on the micro SD drive. Previously we stored data logged files on … Read more
The productivity series of PLCs has a built in data logger. This easy data logger will log up to 64 tag values on a USB (Micro SD) storage device connected to the CPU. The logs will be stored in CSV (Comma Separated Values) file format. Logging can be triggered by the rising edge transition of … Read more
