Practical Tips and Techniques
This offers ways in which you can learn PLC programming.
The C-More can create a drop-down menu. This applies to all models of the HMI controller. A drop-down is a menu that offers a list of options. The currently selected item in the list is always displayed. When the visible item is selected (touched), other items from the list “drop-down” into view, and the operator … Read more
Node-RED will be used on the Raspberry Pi 4 to communicate serial Modbus RTU to a Solo process temperature controller and Click PLC using twisted pair RS485. This will be done on the same serial network so the devices will be daisy-chained together on the two wires. We will be reading the PV (present value) … Read more
The real-time clock on the Click Plus can now be more accurate. A network time service (NTP or SNTP) has been added to the Click Plus controller. This will allow the time to be synchronized with an internet time server or local network. Daylight savings time is quickly implemented with just a memory retentive bit … 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
