ACC Automation: PLC & Industrial Control Learning
Practical Tips and Techniques
Automation Direct BRX Series PLC. This is part of the Do-More family of controllers.
PLC outputs are the next component of our PLC block diagram. The PLC program will control the outputs of the PLC. 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 troubleshooting outputs will also … Read more
The element browser in the Do-More Designer software will display valid memory locations, add documentation, and show how to cast from one memory type to another. We will be discussing the element browser and how to take advantage of this in your Do-More program. Let’s get started.
Node-RED HTTP Request can be used to read any BRX Do-More PLC memory area. This HTTP (Hypertext Transfer Protocol) communication will only read information from our controller. The BRX Do-More REST API is used to read information using a URL (Uniform Resource Locator) or web address. We will be using the HTTP request node in … Read more
We will now utilize Ethernet/IP to connect a BRX Do-More PLC as remote IO on a Productivity system. The productivity series of controllers can use explicit and implicit messaging techniques of EtherNet/IP to optimize data exchanges across the network. Explicit messaging means that the data messages that are transmitted will contain everything needed in order … Read more
We will look at the BRX Do-More FTP (File Transfer Protocol) on our PLC. Using FTPGET and FTPPUT instructions we can transfer files to an FTP server. Our BRX Do-More PLC now has the ability to be an FTP Client. This will allow us to transfer our logged files to an FTP server that we … Read more
We will now look at creating BRX Do-More dynamic web pages on our PLC web server. These pages are great for operator information display. A dynamic web page is a web page that displays different content each time it’s viewed. For example, the page may change with the time of day, the user that accesses … Read more
We will now look at the BRX Do-More PLC Web Server. Ethernet equipped BRX CPUs and the Do-More Designer Simulator can now have a web server. This can be accessed by any web browser using the IP address of the BRX Do-More CPU. A web server is server software or hardware dedicated to running this … Read more
The BRX Do-More PLC Peerlink Ethernet communication network is one of the easiest networks to set up and run. Peerlink is a shared programmable logic controller (PLC) common memory area within a local network. Do-More central processing units (CPUs) or DirectLogic PLC systems using ECOM100 modules can read the entire area and write to their … Read more
The Do-more PLC Modbus ASCII protocol will be used to communicate with a Solo process temperature controller. A sample program will explain in detail how this is accomplished through a serial port. Modbus is a communication method used for transmitting information over serial lines between electronic devices. The device requesting the information is called the … Read more
The BRX Do-More 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 … Read more
