How to use Set Reset in PLC Programming

The Set Coil (SET) instruction turns ON the specified discrete memory location. Once the discrete memory location is SET ON, it will remain ON until it is turned OFF, typically via a Reset Coil (RST) instruction. It is NOT necessary for the input logic to remain ON for the discrete memory location to remain ON. The set coil instruction can be used several times throughout your ladder logic. The Reset Coil (RST) instruction turns OFF a discrete memory location. This instruction is normally used to turn OFF a discrete memory location that has been turned ON by a SET instruction. It is NOT necessary for the input logic to remain ON for the discrete memory location to remain OFF. The reset coil can be used several times throughout your ladder logic. Programming and examples of the BRX Do-More series can be found at this URL: https://accautomation.ca/series/brx-do-more-plc/ There are several reasons why we are using the BRX Do-More Controller. Here are just a few. – Standalone PLC with built-in I/O – Built-in Data Logging – Communication ability – Ethernet Port, RS232, RS485, USB – support for protocols such as Modbus RTU, Modbus TCP, ASCII, K-sequence (DirectLOGIC users), Custom Protocols (ASCII over serial, TCP or UDP over Ethernet) – Built-in Analog input and output – Integrated motion control – High-speed counters – Powerful instruction set (Video of Instructions in software) – Ability to expand the system with a variety of modules – Part of the Do-More series of PLCs uses the same free software. (Do-More Designer) – Integrated simulator in the software capable of external communications for testing #shorts
