  2. JZ20-J-UA24 CONTROL VIA LABVIEW

    Posted

    Hello again,

    Well I tried the Ethernet Configuration process, with all the tutorials, but I don't know why I'm having a hard time doing it. It's unfortunately not working for unknowing reasons. When I got to controller M90  OPLC Settings, I'm inserting everything with the TCP/IP as well as in Favorites my PLC with its IP Address and the local Port, but when I'm pressing the Get Version its either telling me a runtime error 13, or sometimes giving me an error regarding either the cable or the communication or the IP. So if you can just help me get over this barrier because it is giving me a really hard time. My gateway is 10.20.40.254, and i will be using a local port of 502 for modbus. How can this configuration be done in my case, and in the file I have below. And regarding the IP Address which I placed 10.20.40.200, when I ping it from my computer I get response, but I dont know why it is not working.

    Hello,

    I just have a small problem, and I keep on asking some simple stuff, because I'm new to Unitronics, and programming PLCs. I have a JZ20-J-UA24, and I want to read from it, and write via labview. This requires a modbus configuration. I looked at the sample modbus configuration on that unitronics supplies with U90 ladder, and some modbus forums on unitronics, but didn't clearly understand what to do next. So suppose I want to read on labview the temperature measured via a KTC connected to the PLC's analog input channel 1 displaying its value at the level of MI 19, how can I do that?  And can someone explain the configuration of the PLC because I didn't get alot what's going on, or how even to read the IP of the PLC.

  4. Analog Output

    Ok, so basically I'm building a PID controller for a tank, and I want to regulate its temperature at 40 degrees C. I used the heat/cool sample presented by Unitronics. I altered some parts in the code, and at the end through debugging I'm getting the required bits calculated by the process to be ouputed. However, it only outputs 1V during heat mode. Its working quite well during cool mode, but why isnt it outputting anything but 1V during heat mode although it is receiving the correct amount of bits. And I'm sorry I sent you a wrong file previously. Thank you alot for your help!

    Hello, I have some problems in getting out analog output from my JZ20-J-UA24. This is a PID controller, which heats, and cools a tank, and I want it to send out during the heat mode a voltage of 5V, and 0V during cooling. I did all the necessary hardware configurations, but I'm not getting any pulse out. Do you think anything is wrong with the code?

    Well than I need help in coding for a PID controller for a JZ20-R16. I've read alot of sources, and all the sources refer to a function block tab, which my program lacks. If I dont have the tab what are the ways to device a good PID Controller code?

  16. Trying To Connect JZ20-J-R16 To Labview, by RTU

    Hello, I have JZ20-J-R16, and I want to read values from output 1 on labview, but I just have a problem in trying to do it. My PLC doesnt have an Ethernet port, I can just connect it by means of a USB, or com port to my PC. So if I wanted to read from this PLC on labview by means of RTU communication, can someone please give out an easy code to do that (to configure the PLC, and thus assign the addresses to each port)? And if I bought an external mode that contains an Ethernet port and connected it to my PLC, would I be then able to communicate by means of TCP through labview?

    I need help on this ASAP pleasee
