Arduino with Allen-Bradley DF1

Introduction to Arduino with Allen-Bradley DF1 The purpose of this post is to document my progress on using Arduino with Allen-Bradley DF1 protocol. Particularly, for this experiment, I am using an Arduino MEGA with the MAX232 module. The mega has 3 UART ports. Also, I’m using the SLC 5/04 processor. Read More »


SLC-500 Selectable Timed Interrupt

Introduction to the SLC-500 Selectable Timed Interrupt The SLC-500 Selectable Timed Interrupt allows you to guarantee the execution of a routine in a given amount of time. For example, we might have a PID instruction that we need to execute every 50ms. We cannot guarantee the execution time of standard Read More »
