PLC Ladder Logic Random Number Generator

How to generate a more true random number using just ladder logic, even if PLC brand does not have RND, RAND, or other pseudo-random number generators (PRNG) functions. 

The objectives of the PLC exponential random number generator in this example are ...

  • More True Random Number
  • Range Selection Available
  • Universal Ladder Logic Compatibility
  • Scalable Entropy
  • Use 2 or more linear PRNGs
  • End-User Friendly
  • Random Trigger Options

In the example PLC Exponential Random Generator, you will learn how it uses two different linear PRNGs and alternates back and forth between the two random number generators with a user-friendly familiar rung of logic like this ...

The key to this approach is that each of the PRNGs used needs to be on different timing cycles. We exponentially increased the randomness (entropy) by also using different timing trigger frequencies for each PRNG. Then we increase the entropy exponentially again by making the one trigger somewhat random. (A randomly time trigger activating a random generator randomly.)

Here is the video from the article that shows the Exponential PLC Random Number Generator running live on AB/Rockwell's SLC 500/RSLogix 500...

Read the article linked to above for rung by rung and more details.  See this article re-shared on social media will encourage me to write more. So please share it with your friends and associates. Many will find this unique article interesting. I hope you like it.

New Electrical Troubleshooting Game V4

Free Online Troubleshooting Game App

The new version of the free online industrial electrical troubleshooting game app is out!

Level 1: Training on how to use the industrial electrical troubleshooting app and how to perform industrial lockout/tagout via 5 or 6 task. (Max score 100) Completing this level unlocks the skill test mode.

Level 2: Five Electrical Faults to solve. There is even an intermittent fault when the conveyor vibrates, to give players a little bit of a challenge. If a player does not follow electrical safety shown on the previous level, the user gets electrocuted and has to start the game over. (Max score 100) Completing this level unlocks skill test mode so the player can return to that mode anytime they want. It also unlocks the new Rando mode!

Level 3: Five random electrical faults in a race against time! These faults are created using the new V4 electrical fault engine, capable of creating every possible fault for the circuit shown. (Max score 600) Completing this level unlocks the new "Cheatsheet". A new interactive electrical diagram showing live voltages and currents in the electrical diagram. Making it even quicker and easier to troubleshoot. It also unlocks Rando mode so the player can return to that mode anytime they want. They can do another 5 electrical faults and use the cheat-sheet if they want. Or decide not to cheat.

Other cosmetic and functional improvements made to this new version 4.5 of the industrial electrical troubleshooting game. Check it out and if you like, please share with others in your social media and blogs.

Coronavirus Free Industrial Training Simulation Software

coronavirus school closing

Coronavirus quarantine (COVID-19) makes industrial training equipment obsolete. Insightful comparison to the replacement, industrial training simulator software.

In the article, we give several industrial training simulator software solutions and examples. More importantly, valuable distance learning tips and insight are given. Below is an excerpt from the full article...

Schools are now faced with the challenge of how to deliver valuable hands-on training to students working from home. Industrial Simulation Software is a great alternative to instill the kinesthetic learning attribute you would get from in-person classes with physical industrial training equipment.
The nation's schools could be closed for weeks, months or the rest of the school year. Even after schools are re-opened there may be social distancing practices implemented, and physical industrial training equipment may not be adequately or cost-effectively disinfected between each student's use.
Even before the Coronavirus outbreak, industrial training simulation software had some major advantages over physical industrial training equipment in certain areas. 

Summary: Research shows that 70% of what employees learn comes from experience, 20% is from their social interactions, and 10% is from traditional learning sources. The Simulations provided in our courses and as stand-alone software are tools that emulate the real work environment so that students and employees can identify with it. They provide experiential learning so the learner acquires knowledge faster, and retains it longer because they can experience and apply concepts learned in a realistic, controlled safe environment.

IR Corona Virus (COVID-19)

PSA: To stem the spread of the Corona Virus (COVID-19)

In order to stem the spread of #coronavirus, many use non-contact infrared thermometers to determine human body temperature. Our industrial customers may be tempted to use their existing industrial-grade non-contact infrared thermometers.
WARNING: Industrial thermometers are unreliable for human body temperature measurement.
"Unlike infrared thermometers that are designed for medical use, industrial-grade instruments can vary as much as 7.2 Fahrenheit (4 Celsius) degrees from a target's actual temperature."
(Jim Seffrin - Director of the Infraspection Institute)
 So using an industrial-grade thermometer to measure a normal healthy person's body temperature, you might see temperature values ranging from 91.4°F (33°C) to 105.8°F (41°C). Causing you to miss a person who could have a fever (Coronavirus)! You should only use medical grade thermometers that have been certified for such use. Medical approved infrared thermometers are more accurate than industrial grade and provide results closer to the person's actual core body temperature. Read More ... 

Coronavirus Tips:

  • Stay healthy everyone, wash your hands frequently.
  • Avoid others coughing or sneezing.
  • If you chose to wear a mask, only use a n95 mask or better, else you will have false sense of security.

If you are currently under the weather, get well soon.
