BRX (Do-More) PLC PID with PWM Output

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 … Read more

C-More EA9 HMI Series Panel Object List Text

The C-More HMI Panel software uses virtual components called Objects. These objects are programmable to simulate the functions that you require on your automation project. Pushbuttons, Switches, meters, and graphs are just a few of the objects that are available to you. The Text List Objects include a variety of options to customize the display … Read more

Click PLC PID Instruction and Autotuning

A PID (Proportional, Integral, and Derivative) control is possible with the Click PLC. The Click Programming Software version 2.50 now includes PID. This features 8 full-featured control loops with an easy graphical user interface (GUI). PID will run on all of the Ethernet-enabled Click PLCs. We will be using this PID along with a Factory … Read more

Click PLC PID using Factory IO (3D)

A PID (Proportional, Integral, and Derivative) control is possible with the Click PLC. A sample program was written for this PLC by Bernie Carlton in the following thread from the Automation Direct Forum. This was based on the math/process presented by Tim Wescott on is paper titled PID without a Ph.D. We will be using … Read more

C-More EA9 HMI Series Panel Define Custom Keypad

The C-More HMI Panel software uses popup system default keypads. I recently was asked to enlarge the keypad to make editing easier. We will now look at enlarging the existing system default keypads. This is especially good with touch screens over 10 inches. We will also look at how to define a custom keypad for … Read more

BRX PLC INC DEC 512 Registers for DMX512

We will now look at inc and dec 512 registers using the BRX Do-More PLC. This is to control DMX512 fixtures. I was recently asked the following question after posting the Analog Dust to Dawn program: ” I was wondering if there’s an easy way to increment and decrement a range of values. e.g. I … Read more

C-More EA9 HMI Series Panel Object List Recipe

The C-More HMI Panel software uses virtual components called Objects. These objects are programmable to simulate the functions that you require on your automation project. Pushbuttons, Switches, meters, and graphs are just a few of the objects that are available to you. The recipe object changes the value of a tag or multiple tags. We … Read more

BRX Do-More PLC Analog Dusk to Dawn Program

A dusk to dawn sensor usually is discrete on/off of the lighting control. If we want to vary the lights to mimic more of the sunset and rise, we would use an analog output to control the lights. I was recently asked about such a program. Every day they wanted the lights to go off … Read more
