  • The first recorded date of Christmas being celebrated on December 25th was in 336, during the time of the Roman Emperor Constantine. A few years later, Pope Julius I officially declared that the birth of Jesus would be celebrated on that day.
  • Santa Claus's sleigh is led by eight reindeer: Dasher, Dancer, Prancer, Vixen, Comet, Cupid, Dunder (variously spelled Donder and Donner), and Blixem (variously spelled Blixen and Blitzen), with Rudolph being a 20th-century inclusion.
  • Outdoor Christmas lights on homes evolved from decorating the traditional Christmas tree and house with candles during the Christmas season. Lighting the tree with small candles dates back to the 17th century and originated in Germany before spreading to Eastern Europe.
  • That big, jolly man in the red suit with a white beard didn’t always look that way. Prior to 1931, Santa was depicted as everything from a tall gaunt man to a spooky-looking elf. He has donned a bishop's robe and a Norse huntsman's animal skin. When Civil War cartoonist Thomas Nast drew Santa Claus for Harper's Weekly in 1862, Santa was a small elflike figure who supported the Union. Nast continued to draw Santa for 30 years, changing the color of his coat from tan to the red he’s known for today.
  • Christmas 2018 countdown has already begun. Will you be ready???
  • Why do we love Christmas? It's all about the traditions. In this chaotic world we can miss the "good old days." Christmas reminds us of that time.

6 Circuit Multi-Function Chase.mp4

This is a set of 6 circuit multi-function chase lights I have across the bottom of my Christmas LR window. It is run on an Allen Bradley SLC5/05 with 2 PC's and a Windows 10 tablet running AdvancedHMI. There are 5 modes the display goes through, with a light test mode that can be toggled on by any of the HMI's for testing the lights, especially to make sure they're in the correct order. This is made up of 6) 100 light strings running on 120 volt outputs.

Curious.... Why are you using Allen Bradley and not something like a J-Works USB interface?  Isn't the AB several thousand dollars?  J-Works is far less costly (less than $100 and more like $50) for what you want to do.

I got the all the PLC's I have free when I upgraded or stripped out control panels on machinery. The AdvancedHMI software is a free openGNU product and the only special item I purchased for that was a Windows 10 tablet. The only PLC things I have had to purchase was 6 DC output cards for my tree lights, an assortment of plugs & receptacles and a lot of wire. I also have the software & programming cables, and have 25 years experience programming PLC's.
