  3. ASCII Code 8 Byte In Twido

    Hey Guys!!!! I'm trying to use ASCII 8 bites in TWIDO PLC and on MOD BUS TCPIP it connected to WinCC , where I'm trying to read the ASCII in as a STRING char that to in 8bits. The problem I'm facing is that it is getting swapped like if I'm writing VA in PLC then on SCADA it is showing AV. In WinCC there is no setting for word swapping. Therefore Kindly help me for this in plc end
  4. Hi guys, I have tried almost everything and ran out of option on how can I successfully connect modicon m34020 processor using mini USB with unity pro, I am working in Windows 10 and selected everything possibly correct I can, like setting address to USB, and "SYS" in Set parameters, I have USBplc driver installed and it shows, "disconnected" and local and remote id emptly fields. In my device manager, I can see a question mark on the processor driver "BMX CPU" and when I try to update/upgrade/fix it it simply goes to nothing. While the Unity Pro shows the error "this isn't the right address or the plc is too busy or off". Please advise, if i am missing something. thanks in advance.
  5. Hello,I am trying to use ProWORX NXT to view the logic of my Modicon Quantum 534 controller online. When I try to go online with it, it always times out. I am using a TCP/IP connection and my PC is in the same subnet as the controller in question. I can ping the controller's IP address just fine and when I use ProWORX NXT's Net Scan function, it recognizes that there is an Ethernet connection at that IP address but doesn't recognize it as a Modicon controller.Weirdly enough, my PC can connect to another Modicon controller of the same type and in the same subnet just fine.Can anyone help me with this issue?
  6. How to Scale a analog value?

  7. Hello, I got a new work job to design a cycle tester for a mechanism to make sure will work for at least 5000 cycles open - close. I never made a pls program I start researching few days ago and seams to be very complicate to make it. I have a TM221C16R PLC from Schneider. please help me with some instructions. the cycle tester will have a start pushbutton, stop pushbutton, door open switch, one air cylinder with solenoid to push and pull and a counter. Thank you, Romica
  8. Hi! I have my 1756 IF8 wired in high speed differential mode but i can't configure the RTS smaller than 11 ms. What I understand it should be possible to set as low as 5 ms if module filter setting is 1000 Hz. Is there anything else that i have to do?
  9. Mitsubishi Analog

    Good day everyone, I know am quite new in this forum, but... Please has anyone here actually worked with the analog module FX2N-4AD of Mitsubishi?  I have one here with me that I intend to use in controlling a process that will be requiring 4-20mA. Unfortunately, unlike S7-300 or SLC 500, that is quite straight forward, this has been messing with my head since morning. And oh, by the way, am using Version 8 of GX-developer.   Any idea on how to go about navigating this mysterious island will be verily appreciated.   Thanks. Francis
  10. I'm using TM221CE40T PLC with TM3DI16 DI extension. I'm programming it using SoMachine Basic. In the program I implemented a counter (%C0). I've read in the documentation that %Ci.V stores the current count value. I want that to display this value on a Magelis HMIS5T. How could I store the current count value (%Ci.V)? Thanks in advance!
  11. hey!  I'm pretty new to PLC's, and I'm supposed to ''teach'' the people at my internship how this PLC works, but I have encountered a problem.  I've gotten pretty far with all the digital programming and understanding how everything works, but I just can't figure out how the analog inputs/outputs and programming works...... I've had a fair explaination on PID and how this works. I've searched the web as well to figure out what PLC instructions to use.    I hope you can answer my following questions.    1, what are the most used PLC instruction blocks which I can use for temperature control, and how am I supposed to use them? 2, Could you please give me an example on how to use PID and what numbers will I need for the calculations? 3, what are the most used PLC Instruction blocks (apart form the analog ones) that I should include in my tutorial?   this is my setup: Ethernet switch MOXA EDS-205 Plc voeding PA202 PLC CPU CJ1MCPU11-ETN Digital IN (16x) CJ1W-ID211 (SL) Digital IN (16x) CJ1W-ID211 (SL) Analog IN (8x) CJ1W-AD081 (SL) Analog IN (8x) CJ1W-AD081 (SL) TRANS OUT (16x) CJ1W-OD212 (SL) TRANS OUT (16x) CJ1W-OD212 (SL) Analog OUT (4x) CJ1W-DA041 (SL)   thank you soo much for looking at my question and considering helping me! the OMRON helpdesk hasn't been very helpfull.    kind regards,    Deuslupos,
  12. I am having trouble loading the configuration into a Micro984-230. I lost an old M84-002 PLC. I have the program. I purchased a Micro994-230 replacement. I lost my cable, so I made a new one. The only software that I have still running is Updoc 4.30b. I tested out my cable and Updoc by connecting to a 984-381. Everything worked fine online and offline. The error I get during the configuration loading is communication error 13. I have no idea what that is. Perhaps I can't do configuration loading with Updoc. I have Modsoft Lite  working but I do not think that it works with this controller. It is for MIcro and Compact controllers. I may have modsoft and taylor kicking around but I do not know if they are installable or not. I hope I can find out if my config is improper, I have used the wrong controller setup file (used Micro984), or where iI can have the config loaded for me? I also do not know if this used controller is functioning correctly.
  13. FX3G-2AD-BD Store Peak Value

    Good day, I'm new to this forum and to mitsubishi PLC but was hoping for some assistance with a programming issue. I have been through the hardware and programming manuals without luck for this issue. Hardware: FX3G-60mt FX3G-2AD-BE Settings: Structured ladder/FBD Current input mode on: M8260 (first board, first input)   What I need to do is to record the peak value over a cylinder stroke period. The hardware manual explains how to average the value using averaging time, however I basically need to peak hold and send that to a D register for go no-go compare.    Process as follows: Contact closed, monitor D8260, contact open, move peak value from D8260 during monitor duration to D205.    Thanks in advance for any assistance. -Swervomotor  
  14. Hello, does anyone here know what instruction to use to read the analog value from ch0 and display the reading for DVP-10SX plc? I'm lost, need help.

  16. Having problems with the analog drifting. Over time the counts change. I have checked grounding and have tied the analog common to the DC common which helped clean up the noise. I am using a Balluff analog linear sensor 0 - 10vdc for the iputs. Both channels seems to drift. Any Thoughts?

  19. Current Monitoring

    Greetings, I've been having some issues with a vacuum pump breaker tripping... I think I've figured out the problem and resolved it but I noticed that several of the other motors have current monitoring on the HMI but the person who set this up is no longer with us.  I'm wondering what I need besides an analog input for my control logix processor (which I have) to setup this project.  I'm not sure if the other motors are just monitoring one leg of the 3 phases or if they are somehow showing total current?  any ideas and recommendations would be greatly appreciated.   thanks,

  21. I have a PLC, the PLC is TSXP573634 but I don't have a memory for it. I want to connect but I can't. The PLC is new. I used usb-rs232 and TSXPCX1031. When I want to connect I have this message:"This isn't a valid PLC Address, or PLC is busy, or media is off". I need for help!
  22. First post. We recently upgraded our machine from an SLC to compactlogix. In the SLC 5/05 we used analog 1746-ni8 cards for pressure and position sensors. When we moved over to the compactlogix 1769 l36erm with 1769-if16c cards we seen issues where the analog values had very little definition accuracy. This can be resolved by changing the filters but then the response time of the card is to slow and we miss data. All of the relevant code from these sensors are in their own task and ive tried periodic, event and continous tasks but none of this helps. The strange thing is with the SLC we never seen these issues. Any ideas how i can improve the reponse time when the filters are set low?
  23. Have a PLC5 project with remote racks with digital and analog I/O. For test purposes have wired AO to AI and have set up the BTW and BTRs. Problem is I put a value in the N11 register for the particular AO (N11:66 - BTW) and it doesn't appear in the other N11 register for the particular AI it is wired to (N11:4 - BTR). The AI - N11:4 continues to read a value of "8259" in decimal/"2042" in BCD, despite any value I put in the AO N11 register. The range of the AO is 4-20 mA with a Raw min of -4095 and a Raw max of 4095 and the range of the corresponding AI is 1-5VDC/4-20 mA. If I remove the wiring arm of the AI, the N11 register will read "4135" decimal. Would appreciate any fdbk as need to get working as system for customer will not be migrated to newer RA or Siemens system til next year. Cant get support out of AB for questions as only have standard "tech connect" tech support contract and PLC5 requires you to have "Legacy automation" tech support added to your "tech connect" stnd contract.
