  1. Crouzet Millenium 3

    Recently had to get a program out of a millenium 3 plc which I had programmed a few years ago but the cable would not connect.The only difference this time ,as my laptop no longer had a rs232 port,was the use of a USB to rs232 converter. Having trawled the web I managed to find the circuit of the interface cable below. It looks like the signal from the computer uses the negative going part of the pulses which aren't present on most usb to rs232 converters. Is this correct?

  3. View File NJ/NX Get IP Address A Library containing a function Block that can be run on any Omron NJ or NX PLC. The Function Block will retrieve the host PLC's IP address, Subnet Mask, Gateway, and MAC Address. The Port Details are presented through 2 structures , 1 per-port. In the event the PLC only has one port the structure for Port 2 will be blank. Submitter photovoltaic Submitted 12/12/22 Category PLC Sample Code

  5. Is there an efficient tool to manage and validate CX-Programmer addressing. Requirements: - Highlight Duplicate Address allocation - Compact/Defrag address range to avoid wasting memory space. Note: - Any FINS addressing will have to be reconfigured - This approach assumes symbol use rather than direct addressing in the logic.
  6. Hello, Good Day All. I am facing this issue while I am going to copy old plc to new plc. but old plc having 4965 steps, once going execute this program to new plc its showing more than 8000 steps. please suggest on this. PFA.
  7. It will de nice to have an option for getting a cross-reference report for the AT address used on programs , as is now its easy to make mistakes double setting the same AT address on a program , specially this days that supplies of NA screens are not always availiable and using memory address is necessary for NB screens and SCADA communication and is difficult to keep track of the used address on a program , some times in global or in internals, right now its easy to make a mistake and use the same address twice , and this wont be detected on the compiling
  8.   Hello, I downloaded the program from the M251 PLC program, using the SoMachine4.3 environment. However, the downloaded program does not compile because the library is missing. The library is from a different manufacturer. Is it possible to find this library on the M251 PLC device? is there any way?

  12. unit of time in D8284

    Hello PLCmaniaccccssss, What is the unit of time in 'average time for the channel -1' (D8284) while programming for analog inputs? I have moved k10 to D8284 in my program in gxworks 2, does that mean the time average will be taken for 1Sec or 10msec or any other time unit??? I require this to eliminate the flickering of the input from the load cell transmitter. Thanks and God bless!!!

  16. Hello everyone,  I have a Panelview plus 600 ( I know it’s old but I’m trying to get it to work). It’s on a yogurt bucket filler, I don't have any application to run or to do anything. What software do I need on a computer to be able to transfer it to the panelview. Is this even possible?  There is nothing in the memory right now but how to I program it and what program do I use?  I’m in the Los Angeles area and even willing to pay for someone to come and do it.  I need to get this to work, thank you so much. 
  17. GX Works 3 (R04CPU) Device Memory

    Hello,  GX Works 3 / R04CPU. I'm using the Device Memory so that I can link the HMI to my PLC. I've set aside some memory, in this case D3260, to be used as a Real (32 bits data, Float single precision) to be set by the HMI (operator adjustable setting) and read from the PLC. I thought I'd move D3260 into a local label for readability/testing purposes, and it says I cannot move an Int into a Real - which is fair enough, but, how/where do I set D3260 as a real? Do I use some Functions to take D3260 + D3261 and make it to a real, or define the data area as a real somewhere...   Dumb question I know, I'm new to GX Works 3. Thanks very muchly

  19. Good day everybody,    Currently I am working on an application using 3-axis controlled by a QD77MS4 Simple Motion Module.  In this case, I have already set up most of the configuration, but when I try to execute the program, I get the following error:   SP. UNIT ERROR - The location designated by the FROM/TO instruction set is not the intelligent function module/special function module.  - The module that does not include buffer memory has been specified by the FROM/TO instruction.  - The intelligent function module/special function module, Network module being accessed is faulty.  - Station not loaded was specified using the instruction whose target was the CPU share memory.   The QD77MS4 Module is mounted in Base Slot #3, so I use U2\G800, U2\G1500, etc... to Read/Write from it.  The Diagnostics tool indicates the error occurs as soon as I try to access the U2\G800 Buffer Memory. If I set this part of the program to No Execution the error is no longer displayed.  Additionally, if I try to monito the Buffer Memory area of the Module, it says that "The Module Stat Address is incorrect".   I already tried changing the position of the module in the base (Slot 3 --> Slot 1) and changing the corresponding values to reflect that, but still the problem persists.    What am I doing wrong? Is there some kind of configuration I could be missing?    Thanks in advance for your help!   
  20. I am trying to online edit a program in a MELSEC QCPU, using GX Works2, but I keep getting this error "A file which does not exist in the PLC was specified" <ES:010a4022> Few weeks ago I had just online edited the same program in the same PLC with the same steps with no problem. There had been no changes to the PLC after that. Just all a sudden when I try to edit yesterday I get this error. Not an expert in Mitsubishi, just started learning the basics. Connection to PLC is by USB cable. Steps I followed to connect to PLC:    -Online > Read from PLC    -Select PLC Series: QCPU (Q mode)    -Select PLC side I/F Serial Setting: Serial USB    -Select all target program to Read, then Execute I am editing the file that I had just read from PLC Steps I followed to online edit:    -Online > Monitor > Monitor (Write mode)    -Execute the function below when mode is changed: Checked all    -Edit the program (basically just deleted one -||- contact and drew back the line)    -Compile > Online Program Change Then Bam! error get! "A file which does not exist in the PLC was specified" <ES:010a4022> I had tried Verify with PLC, but all results match. Is there something I am missing? Help much appreciated!
  21. Hi fellow PLC veterans, I am new in the PLC world so please forgive me if my questions read dumb to you..   I am just wondering if there are any newer PLC machines that can: 1. keep the program even after its battery is completely flat or faulty  (Is this even possible?) 2. allow users to copy and save the program somewhere so one can install the program again without the need/presence of the machine supplier What tools/software may be required?   Thank you for reading and look forward to your response :)
  22. Hello, I am started working on Gx Works 3 recently, actually want to know if I can access local labels from other program body or can call them to other program body?
  23. Unconverted Ladder Code?

    Hi All, Please see attached screenshot: Whenever I want to save the ladder program or start simulation, this window pops-up. If I press 'yes' I loose the whole work. I tried to open existing program and modify it, but it did the same. When I clicked 'yes' I lost all modification and just the original program remained. (I made the program in the morning, opened and saved many times but it started popping this window later.) I work with FXCPU series, FX3U/FX3UC type, simple project in ladder. This worked well but now is not anymore. I use Melsoft GX Simulator! Can anyone advise why this is happening? It is very annoying! It is pointless to work on anything now! Many thanks
  24. simple motion cam curve

    Good afternoon, I have a problem in an application for a rotary knife, I'm using a MR-JE-B servo to make this movement, while my material is powered by an inverter connected to a modbus rs485 network, with a 5v encoder connected directly in motion. I'm having some problems and I think it's my cam curve. I have a very high refeneration, and the system doesn't obey the size of the length I want the cut. It always cuts the same size, regardless of the configuration I use, it always cuts to 245mm. Put some photos, how are my settings. Grateful in advance, if anyone can help me.
