  1. I have this hardware configuration of an extension rack for a M580 PLC projet using EcoStruxure Control Expert I export the.XHW file by following the procedure below: https://www.se.com/uk/en/faqs/FAQ000256454/ And I am trying to rename the DD1602 card using the file, however, when I rename the card as a show in the next image (selected in green), and re-change the file to the .XHW extension, when I re-import it into Control Expert, I get an error saying: unknown fatal exception, even though the only change I've made is to the name of the card. I know I can rename IODDTs instances manually in Control Expert, but in fact I'm trying to automate the process of renaming IODDTs because I have a lot of IODDTs to rename, which is why I thought of using the XHW file. Does anyone have an idea of what I could do? Thanks in advance
  2. FX54AD

    Hello all, Quick question - I know where to set the "number of samples" for averaging the analog inputs, but is there a buffer memory or similar that I can access without having to resend the application to the PLC ?    What I want to do is just fine tune one channel as the system is operational. cheers.
  3. MELFA ASSISTA COBOT

    Hello all, is any one aware of any good free training, guides, etc, I am using the RT Visual Box and I like it a lot, but need a bit more in depth info and manual is ok, but it does not explain things in great details more like a general view.   Many thanks.
  4. Hi everyone, I have a question for you all, Is possible to configure CJ2M-CPU11 with tags trough network configurator to connect Control Logix PLC using EthernetIP? I did a configuration with CJ2M-CPU31 and Control Logix PLC with no problem, but now I need to communicate CJ2M-CPU11 with Control Logix PLC using EthernetIP. Some of you did this configuration between this two PLC before? Regards!

  7. Change PLC model in GX Works 3

    Hello. The project I'm in have decided to switch cpu-model from R04ENCPU to R32. It does not seem possible to change it in the module config / hardware view. I try to delete the old CPU, but cpu module cannot be deleted... Anybody know?
  8. Hello all, I have the need for PLC to calculate a giving time shift pattern, so if I start Monday 8am on a 24h prod basis, and the production run is 48h, the PLC should tell HMI finish time is Wednesday 8am, that is ok, the problem is, Production stops from Saturday 8 am, and starts again Monday 8am. Thus if I start prod run on Friday 8am, PLC should tell HMI (Got2000), production finish time should be Tuesday 8 am. I can read RTC, compare, do maths, but how can I miss or not take into account Saturdays from 8 am till Monday 8 am...that is my problem.   Any thoughts, ideas, are all welcome. Thanks.
  9. Inverter nameplate

    Hi,  Do anyone knows what is the meaning of the following inverter nameplats characters ? FR-A840-00023-E2-60 Mainly the beginning with the FR-A. Thanks ahead.  
  10. Hi from Colorado, Panel Builders @ MRPLC~ I bought a custom 508A assembly from a UL shop (277/480v 3 phase). The prototype didn't work out very well so I'm revising the design for next time. Before I present my "red line" revisions to the fabricator, could someone advise if I'm OK to simplify part of the work in a particular way? I just need to make sure my simplification doesn't run afoul of the 508A standard. My clients requested that a ten watt 120vAC amber LED (distant from the 508A cabinet) should light up whenever the 3 phase bus is energized. The panel fabricator provided an SSR solid state relay to close whenever 277v shows up across the "input" terminals & they fused the 277v hot for the input so that's all good. The "output" terminal is "single pole normally open", rated for 10 amps. The power that I'm sending in from outside the cabinet is from a small UPS system where the inverter is rated for 250VA's--so it can't deliver more than two amps @ 120vAC.  It seems to me that I don't need the series fuse that the shop provided to protect the 10 amp rating on the SSR--since my input power is already current limited. It also seems that I don't need to bring the associated single phase neutral wire into the 508A cabinet at all--since the neutral is never switched & it's doing nothing inside the 3 ph. assembly. If I revise the drawings along these lines, I'll eliminate two terminal blocks, a cc fuse/fuse holder & some wire...and this part of the assembly will be simpler & more intuitive.  Basically, I want to treat the SSR like a switch leg for the light, running only a 120v hot wire to & from the SSR output terminals. I don't want to revise the drawings, however, unless I'm sure the fabricator won't have to change them back to comply with UL 508A. I don't own the UL "standard" document & I don't know the peculiarities...but I'm sure some of the forum members do.  Should I add signage to explain that the 120v hot must be current limited or OCPD protected before it enters the 3 phase cabinet? Thanks in advance for any coaching or suggestions.      
  11. Melsec Medoc K2N

    Hi, I have a client with an old K2N CPU configuration. Is there a communication module that I can use, so that I can upload the excisting program to my PC with my old version of melsec medoc, over RS232? We need the program to upgrade the PLC to a new type. But they don't have a program or a listing of the program.
  12.   Hi guys.   On our company we got several different PLC system but right now I´m focusing on a Mitsubishi Q-system with device-net master QJ71DN91.      We are going to make communication with SMC-JXCD1 controller for a actuator.   But I have no experience with DeviceNet and unfortunately there is no files, functionblock, or program examples what I can find.  Not even Mitsubishi or SMC had some for these two together so I turning the Question into this forum instead😊   Previously I´ve used profibus on a fx3U system and FX5U-Simple CPU communication protocol to talk with slaves in a network.    I got on hold of some old document from Beijer from where I got 3 functionblocks for devicenet.    1.DnInitiateQ  2. DnSupervisorQ 3. DnDataQ 4. DnMessageQ     So maybe I can have some help from these but I´m still not sure how to send/receive information to the SMC-nodes.   I´m a little confused about if I should use the master with I/O communication or  master with explicit messages?  The later I haven´t even heard of.    I was only thinking about creating array of word to receive and send info to the nodes.   But my knowledge of this communication protocol is very low.        Anyone know´s how to get me started?  Or can provide some kind of example in GX IEC or GX works.       
  13. control panel for sale

    Hi all, Hope everyone is doing well. I'm currently in the process of starting a home based control panel shop. I have about 8 years of control panel building experience and about 2-3 years of being shop team lead/design engineering. I have been planning this for years and now I have my shop full of necessary tools and material to build small/medium sized panels. I have gone through all the training and examination(which was not easy) to be able to produce UL508A approved panels. My goal is to produce a steady work load with great quality. Now I just need an opportunity with customers which I find to be the hard part. I have been contacting local industries but haven't had any luck. If anyone out there is seeking control panels built at a good competitive rate please advice.
  14. We are seeking a Control Panel builder in the SE Michigan area. We can supply the drawings, components, enclosure, etc. Typical panels include PLC, HMI, VFDs, and standard components. Please contact us if interested. We can send more details as needed. We typically need 20-30 panels in a year.
  15. Hi all  I need to view a project in instruction list format on Mitsubishi GX Works 2. On GX developer the shortcut is Alt + F1 or View tab then press instruction list.   Thanks 
  16. Hi All, I'm new to using PLC, and my background is majorly programming. I am learning how to control a PLC over the internet using HTTP or TCP/IP. I have a Mitsubishi PLC Melsec FX-5U 32MR and my requirement is, I want to send create a setup where the PLC works more like a Client on the network and reads values from the server (which is a computer). The outputs on the PLC are controlled by the values on the database in server.  So, lets assume I have a value like this on the server "1,0,0,1,0,1", it should translate like below: Y0 = 1 Y1 = 0 Y2 = 0 Y3 = 1 Y4 = 0 Y5 = 1 Is there any guidance where I can read through and learn how to do this. I would prefer doing it by ST programming and not Ladder.
  17. Logic issue, or problem with Control Expert 14.1?   Pop-up box, followed by Control Expert crash.  PLC seems to be running fine. "Control Expert Fatal Error" "The thread tried to divide an integer value by an integer divisor of zero" Anybody seen this before?  Corrupt file?  Reboot?  Uninstall/reinstall?
  18. CC-Link IE Protocols

    Hello, There seem to be a lot of different CC-Link IE protocols: CC-Link IE Field Basic CC-Link IE Field CC-Link IE Field Motion CC-Link IE Field Safety CC-Link IE Control CC-Link IE TSN This causes me some confusion. Are there as many variations of Ethernet/IP and PROFINET? Can you point me to a good comparison of the different CC-Link IE protocols? My understanding is that: CC-Link IE Field Basic: 100 Mb/s Non-deterministic? Good for non-time-critical communications (e.g., setting a drive speed) Implemented in software Traffic can co-exist with other TCP/IP traffic Max 64 stations Addressed by IP address Star topology I believe the other protocols are all 1 Gb/s, are deterministic, are addressed by station number, are implemented in hardware and each needs its own isolated network. CC-Link IE Control is used for communications between PLCs and robots. CC-Link IE Field is used for remote I/O and CC-Link IE TSN is used for even faster remote I/O communications. Please let me know if any of this is inaccurate. Thanks,
  19. I've set up 20 or so of my alarms under the 'User Alarm Observation' section. I then added an 'Alarm Display (User)' object. Will this object display my alarms when they come in? I'm noticing an Alarm ID section in the 'Alarm Display (User)' object section. What is this Alarm ID for? Can the 'Alarm Display (User)' object only display one alarm? That doesn't seem to make any sense? How would I got about configuring this object so that it will show all my alarms as they come in? Thanks!
  20. Hello and good day I have a Mitsubishi fx1n-14mr PLC controlling a band saw. The PLC is connected via a DB925 - MD8M cable to a Beijer/mitsubitshi E100 HMI for communications and as a power supply via RS-422. When powered on the display on the E100 panel fluctuating, i.e. the screen turns on and off repeatedly. If the main switch is then switched off, then on again the screens seems to stay on and the machine operates normally. The PLC has a built in AC/DC power supply and I suspect that is may be the problem. Is is possible to switch out the AC/DC module? To make sure that the E100 panel is not the problem I want to connect a 5V external supply to the port located on the back. Is it safe to have the RS-422 and the 5V external supply connected simultaneously?
  21. Hi, This is my first application working with a Mitsubishi HMI GT2107-WTBD using GTDesigner 3. Is it possible to have an Ack bit going from the HMI to the PLC when the operator acknowledges an alarm? I've found how to set up comments for alarms and trigger alarms but can't figure out how to link an ACK bit back to the PLC. Thanks.

  25. Hi all. I am new to Autonics and Mitsubishi. I am trying to read and write the data of an Autonics TK series temperature controller using RS-485 with QJ71C24N-R4 coupled with Q00UCPU. I have the hardware setup as attached images. Software setup are as follows:  TK4 Settings: Communication address: 01-99 Communication speed: 38400bps Communication parity bit: none Communication stop bit: 2 Communication Response waiting time: 20 Communication write: Enable Mitsubishi Intelligent Function Module: CH2: Operating: Independent Data Bits: 8 Parity Bit: None Even/Odd parity: Odd Stop bit: 2 Sum Check code: None Online Change: Enable Setting Modifications: Enable Communication Rate Settings: 38400bps Communication Protocol Settings: Predefined protocol Task to be carried out: 1. Read SV 2. Read PV 3. Write SV I have the address for the modules but I am not sure how to communicate or the program which allows to reading/writing. I had tried to follow the attached PDF but i cant key in the first line as there is a bit with "G450" which has an error stating "the device No. is over usable range" and  "An unusable device has be designated". I hope someone here could guide me in writing the program, or any reference for me to follow.  TK-Q02H_RS485_EN_Technical_support_180823_W.pdf
