  1. 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?
  2. So I ordered a V350-J-R34 controller to input a couple analog signals from a couple pressure transducers. I'm reading the installation guide, and I don't know if I'm just reading it wrong, or legitimately confused here. It says this controller has 2 analog inputs, and that terminals 14 and 15 may be used as the analog inputs. However, when I scroll down to the analog input wiring diagram, it shows the positive end of the signal wires landing on terminal 4. HUH?!?!?! Can someone shed some light on this? It's making me feel stupider by the minute. image hosting free upload image online
  3. Good day, I need a few pointers. I am fairly new to Unitronics and the UniLogic systems. I have some experience with ladder logic from past projects, the most recent of which used the Keyence ladder builder software. It’s like coming out of the Stone Age! If I need to separate this into sections please let me know. I appreciate any guidance you can provide. I am working on a project for a production machine. The machine is utilizing modular design from discrete components that can function on their own, so I am somewhat limited on my approach options. I will try and outline wh
  4. Hello, i have a JZ20-J-T40 and four 4-20mA pressure sensor´s. I need connect for two 4-20mA sensor´s for 0-10V analog input´s. How it could be done . Can i use 500ohm resistore? Sorry for my bad english.
  5. Hello, I am new to PLC programming, and I´ve been assigned this task at USP-070-B10 with UIS-WCB1, using Unilogic 1.23.25: I have an analog angle measuring sensor, which gives current of 0-20mA( 0mA is for -45°,20mA is for 45°) , which transfers into integer value from 0 to 16383 in INT16, I need: 1) transfer the integer value to value in degrees 2) display the value in degrees on the HMI field 3) compare the value with user written value in another HMI field, and perform actions according to the comparation I am stuck at the first part, transferring the integer value
  6. Hi everybody. I need some help because I have an issue, trying to use a Beckhoff BK5120 | CANopen Bus Coupler with a V1210 PLC https://www.beckhoff.com/BK5110/ with the next configuration 4 KL1114 DIGITAL INPUT (4 SINKING) 2 KL1408 DIGITAL INPUT (8 SINKING) 1 KL2134 DIGITAL OUTPUT (4 SOURCING) 2 KL2408 DIGITAL OUTPUT (8 SOURCING) 1 KL3061 ANALOG (0-10V) INPUT https://download.beckhoff.com/download/Document/Catalog/Main_Catalog/english/separate-pages/Bus_Terminal/KL3061.pdf The issue that I have is that I've never used a
  7. Hi and Happy New 2018 all! Maybe this will sound like a dumb question, I am beginner in programming in VisiLogic, so is there any way to compare current value received from an analog input with a previous value received from the same input. I have tried to use the 'Store Direct' with MI0(analog input operand) value to be stored in MI1 and tried compare MI0(A) with MI1(B), but it always gives me the same value. How to memorize previous value and be compared with the current? How to make MI1 hold the previous value, MI0 to hold the current, and untile they are compared MI1 is not overwritt
  8. Hi! I have in my system a SM43-J-R20 PLC and A Frequency Inverter from Vacuum (Schmersal). I jus want to show the frequency of the motor on HMI. Think in using I6 as analog in, i did the JP8 and JP9 both to B (current) The thing is, I don't kwon how to wire it. See the manuals below. PLC/HMI Frequency Inverter Manual Terminal 18 (Analog Out) Terminal 5 (GND) Terminal 13 (Digital Out Comum) Anyone can help me? Thanks!
  9. Hi guys, It would be great if we had a high speed analog I/O combined module with 16-bit resolution for Unistream. Conversion time should be 0.5mS or even less, if it's possible. There are applications where is crucial to have such an expansion module.
  10. Background I'm working on updating some of our test equipment. The current setup uses two 20 gallon vacuum reservoir tanks, two manual needle valves per tank, 4 solenoids for tank vacuum controls, 2 differential pressure controllers with DC output, and one PLC. It also uses a very manual process for setup. My goal is to replace the main control box with two analog proportioning valves, 2 analog pressure transmitters, and one PLC with the PLC controlling the vacuum levels inside the tank automatically through data tables. I have a slightly different setup in testing right now but
  11. Are there plans to do a higher resolution analog I/O modules such as 16, 18, or even 24? I know we have several applications that would benefit from the increased resolution.
  12. I have some problems with analog SSR (Celduc, Carlo-Gavazzi, etc brands) when I try to control from an 4-20mA analog output of OPLC. For example with the V200-18-E2B the load impedance is 500Ω maximum for current output. The input dynamic impedance of the SSR is ≥ 100 Ω but a drop in voltage ≤ 8 VDC @ 20 mA. The application doesn't work from 4-8mA, I suppose the dynamic impedance of the SSR will be higger than 500Ω. I found one solution to use several SSR with an analog output, inserting a Power Suply between the output and the SSR. Do you use it any time? does it secure for the analog outp
