Hi all. I'm looking at upgrading my Arduino controlled 2axis solar array. I have the Arduino controlling the panels with a few yearly adjustments manually changed. I'd like to upgrade the system to a Jazz if possible as we have played around with them a bit before and Unitronics hardware is more robust. We have a JZ10-11-R31 Question is I have an algorithm the tells me the position of the sun using a RTC which outputs Altitude and Azimuth and the array goes to that point, how do I go about using complex math like this in U90. ie sin, cos, tan? Can I import a
Hi. I have a Unitronics JZ20-R16 (Jazz2) controller I’ve programmed to run a simple air ventilation system in my house (The thing is running great btw.). I also have a self made Arduino based data logger (I use it to monitor and log my energy consumption, temperature, etc.) I’m not building those things or mass producing, Arduino electronics is my hobby - I just use it to stay sharp. So I decided to cross-integrate my air vent. Controller with my data logging unit (I want to see the status of my air vent. Controller unit on Arduino). So for starters the task is to simply send a 16b
Hi, I'm running an Arduino-based home automation system. My custom-made Arduino clones are communicating over a RS485 network (configured as 8N1) using Modbus RTU protocol. Thing is that I want to have a reliable, industrial-grade PLC in the network, in order to monitor my Arduino-based sub modules. Basically I need a cost efficient Unitronics PLC capable of connecting to RS485 network, The ladder program is expected to be non memory hungry, also I'm fine with good old 2 line display. The PLC must be able to connect to the RS485 network without the use of any extension modules/communication m
Hi I have Unitronics V570 controlling my home's central heating system and I would like to make a webpage, that I can visit on my computer to see values from controller. But the thing is that I want to have a line graph to show temperatures from the past measurements. I have no clue on how to do so, because as far as I understand, you can't get values from data table(which probably will be stored on SD card) to your webpage, you can only get things like MIs and MBs and such. Only way I have figured out to get said graphs is to download data table from controller to computer and then do some m
