Productivity 1000 Series PLC PID Instruction

PID Loop (PID) Instruction (Auto Tuning) A Proportional-Integral-Derivative algorithm is a generic Control Loop feedback formula widely used in industrial control systems. A PID algorithm attempts to correct the Error between a measured process variable and the desired setpoint by calculating and then outputting a corrective action that can adjust the process accordingly and rapidly, to keep the Error to a minimum. The following links will explain the PID instruction. https://www.csimn.com/CSI_pages/PIDforDummies.html http://www.ni.com/white-paper/3782/en/ https://en.wikipedia.org/wiki/PID_controller We will be using an immersion heater in a cup of water to keep the temperature at a constant value. Using the Productivity Suite software we will perform an autotune on our PID instruction. Our immersion heater will be controlled through a relay using time proportional control from our PID output. Let’s get started. More information can be obtained on our website. This includes all of the links mentioned in this video. https://accautomation.ca/productivity-1000-series-plc-pid-instruction Here are some previous posts in this Productivity 1000 PLC Series.

Here are just a few. - 50MB user memory - Can handle very complex applications easily. - 4 built-in communication ports – Easy connectivity to your network. - Data logging up to 32 GB on a microSD card - Add up to 8 IP modules to communicate to your field sensors. This will give you a total of 128 discrete IO points or 32 analog IO channels. - Free Software and 30 days of free training with every CPU from Automation Direct. - Interactive PLC Configuration Tool - Tag Names - Auto-discovery IO – Physical I/O tags will be generated based on each module’s position in the base. - I/O Modules have QR codes under the wiring cover. This can be scanned so you can have the latest specifications/wiring diagrams for the module. - Limitless PID – Autotuning – Individual or Cascade Mode - etc - Web Server and Mobile Access - Advanced Software instruction set The Productivity 1000 series of programmable logic controllers currently has all of these features built into the P1-540 CPU. This CPU (Central Processing Unit) is also known as MPU (Multi-Processing Units) because of the communication capabilities. https://www.accautomation.ca
