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 am facing troubles while trying to log and later display time using Jazz2 controller. So, I'm trying to make an error log. When the error occurs I store current content of SI31 (RTC time) to MI (MI33 in this case - so far it's working). Then in order to display the error I pass MI33 content to MI41 (MI41 is linked to Time Function variable (in CT format) that is then displayed on HMI) . You can see the whole process in images below. The problem is that in the end, the content of MI41 (decimal 1500 - which I corresponds to 15:00 time) is then displayed as 05:DC on the HMI display. I
Hi, I have a JAZZ2 PLC(JZ20-JT40) with OS V2.35(B08) and with ethernet addon(MJ20-ET1). The plc comes with 2.36 OS but, I have to reflash it because its totally crashed somehow. I can't start it. I am able to connect with the programmer software(V6.6.6 latest). I want to acces to the plc by modbus communication. I set up the sample program by the instructions on the help topic. The modbus topic is shows that, I must store some values to SI. I attached the screen of the sample program. I think the SI values displays weird values. What do I wrong? Thank You
Hello, We have a problem with Unitronics Jazz 2 series PLCs (JZ20-R31, +adapters MJ20-RS) trying to connect to modbus communication line. The problem is we cant initializate RS-485 com port, every configuration are restored to factory default (9600;7;1;even;n) after RS-485 cable connection to PLC and in system menu it is impossible to change communication parameters if RS-485 cable is connected (RS-232 com port we do not use). We do not have any problems with Jazz 1 series plcs using almost same program, same configuration. + U90 ladder we are using last version (v6.4.9) + Unitronics
