One of the simlpest hand made TC. http://www.cookingissues.com/index.html%3Fp=1099.html -
I'm curious about the answer also, but I, too, suspect the solder joint. I'm also wondering what the going rate is for the J. Tauser & Assoc. ad placement - I'm always looking for additional sources of revenue. -
Hey All, I'm working a a little home workshop playtime project... I'm using a V570 with a V200-18-E3XB snap I/O module. I "hand-rolled" some type T thermocouples (wires at the business end tightly twisted and soldered to create my TC junction). Each T/C is about 30 ft long, and a direct connection with the E3XB module. I find that the readings I get at room temp are about 8 deg F higher than I get with "real" thermometers. I know I can build an offset into my readings, but curious where the discrepancy lies; Does the solder (60/40) that flows through the twisted Copper/Constantan junction create an offset? Does this fall within the expected accuracy of the E3XB module? Or is it something else? Anyone have any input on this matter? Regards, JohnR -

This will be a quite a challenge for your first PLC project. Start by downloading UniLogic and the separate example programs collection. Watch the UniLogic training videos at https://www.youtube.com/c/UnitronicsProgrammablecontrollers/videos Post a link to as much information as you can about the robot's communication protocol and interface type. Take the leap and start to build a UniLogic program based on what you understand. When you run into a wall, post the program with your questions. Joe T. -
I have almost no experience with programming PLCs, I am still waiting for my Unitronics PLC to be delivered, I have taken on a new project to control a Mecademic Meca500 industrial robot using the Unitronics stand alone PLC via ethernet, Although I do not have the PLC, I do have the Meca500 operating via its web interface, As a newbie I need guidance on creating the needed communication settings within the UniLogic software,
