Practical Tips and Techniques
Automation Direct BRX Series PLC. This is part of the Do-More family of controllers.
PLC memory is very similar to personal computer memory. There is the operating system and firmware of the processor and connected modules. PLC programs and data that are used by the program are also stored in the memory. We will now look at the basic understanding of memory in the PLC. Looking at two examples … Read more
All Solo Standard Process Temperature Controllers that support RS-485 serial communications can use the SL-SOFT configuration and monitoring software. This free package will communicate to monitor multiple SOLO controllers using Modbus RTU or Modbus ASCII protocols. We will be installing the SL-SOFT configuration and monitoring software package on our Windows 10 PC. Communicating through our … Read more
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
