  1. I am currently trying to connect my OMRON NX1P2 1040DT1 (Using CIF-105) to my Unitronics V570 PLC, With my OMRON PLC as Master. It seems as if Unitonics Rs485 only wants a six-wire connection type but my OMRON PLC wants a 2-wire or 4-wire connection, Wondering if anyone has a solution to my problem and can assist me.  
  2. 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.
  3. 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.
  4. Hi, Does anybody know if its possible to access the "Inhibit Module" tick box within the Hardware Device Connection tab from the PLC code? I'm hoping to turn this on / off depending on whether certain modules of machine are physically installed.  e.g. A Kinetix Drive / Point IO etc. Thanks
  5. Hi all, I'm not shure if I saw it once, a Spanish site with a rugged I/O shield for an arduino plus a software package to build an Arduino-PLC packet. It was pretty much $$$ raised... (on my oppinion, for my application, not to dispretiate their value). Has anyone thought of it or knows of such an ensemble: A general Arduino board, a general kind of "plc-shield" (some inputs, some outputs,...) and finally, a (preferably open-source) software package to make an off-the-shelf Arduino-PLC ish? Maybe it all exists with some name changes, or this question is of a huge ammount of ignorance. Thanks. Corvo (means Raven) 
  6. 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.
  7. 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?
  8.  I've been debating whether to stay at my current employer who uses Emerson PAC software, vs going back to a similar company that uses Rockwell (compact/control logix) mainly because A-B is used by most companies around here. I work as a technical temp, usually 12 month contract jobs. Learning the Emerson PAC (aka Prophecy) seems to be a waste of time, since I am not aware of any companies that use it, other than my current employer. My placement company is pushing back, but I know I am correct. I do not have hard numbers, but I've been around the industry for 20+ yers, and have only seen 1 company use Emerson.   Does any one agree or disagree, or have some circumstantial evidence of the actual market share of A-B vs Emerson. I am mainly working in the Auto industry, in Michigan. Just looking at this site, there are 3200 postings for GE and Emerson combined, vs 58,000 postings for A-B. 
  9. HI, I'm reading values from an SBC SAIA PLC ( PCD2.M5540 model). My problem is that some values are 32 bit, while modbus return 16 bit values, of course. Registers are consecutive, so I cannot read for example 9008 and 9009 since they store 2 different information.To make it clearer I attach the PLC watch window. As you can see R9009 is a 32 bit value, but I can't require R9009 and R9010 via modbus since in R9010 register there is a different information. AS well as in R9008. Speaking with SAIA technical support, they explain me that their PLC registers are natively 32 bit, so in order to read them I need a 32bit modbus client. I cannot find anything like this, neither I can use standard modbus, since the buffer I get back is a 16 bit for each register. So 16bit for R9008, 16bit for R9009, 16 bit for R9010. What I can do?Thanks
  10. I'm trying to exchange some data between two controllers. I've used a manual which describes Tag Datalink communication. Everything works fine on the Bradley side, which means I can read values from Omron without problems. However, on the CJ it isn't working. In the Network Configurator I get error every 10 sec (Tag data ling error, code 03D5) and cannot read any data from AB. When I open Connection Structure Tree I see that the input tagset from AB has 'Broken path (0000000000000)' and Unknown Device right next to IP address. I've tried using EDS from the Rockwell as well as uploading it from AB PLC directly - I don't know if it might be EDS issue. The only thing I noticed that inside CJ2M-EIP21 EDS it says that Ethernet/IP is Class 1 connection, however in the 1769-L35E EDS Ethernet/IP is Class 2 connection. Have anyone ever had such a problem?
  11. Hello, everyone! I am following this YouTube tutorial where it teaches you how to add a block of Modbus server within Studio 5000 for communication with plc ControlLogix. The video: https://youtu.be/qcF4m7rPjkw However, according to a comment from the author of the video himself in my comment I can make such a connection through a Modbus device. How do I do this within ur5 and how can i access UR5 inside Studio 5000?
  12. Gx Simulator3 and TCP modbus

    Hi, I'm new to the Mitsubishi world, so may be anyone help me in a quick! I need to test a my client with the Mitsubishi MODBUS tcp.  To do this I would like to avoid use a real plc and use  the Gx Simulator3 that come with the Gx Works3. The question is: the Gx Simulator3 is capable to simulate a MODBUS tcp module? To be more specific I tried this: - created a project in  Gx Works3 with a FX5U CPU. - configured the FX5U built-in ethernet module with IP address of the hosting pc (also tried 127.0.0.1 with no success). - activated and configured the MODBUS muster to the built-in ethernet module. - wrote a trivial ladder program with a 1 input and 1 coil. I can download and run the project on the Gx Simulator3 but I cannot connect to tcp port 502 that I supposed opened by the MODBUS muster functionality of the build-in ethernet module. Do anyone know if the Gx Simulator is able to simulate modbus tcp functionality?   Thanks in Advance Luciano.       
  13. Modbus Tcp Ip Simulate

    Hi guys I need to test some code in an FX5U PLC,  but I don't have the PLC here so I'm trying to simulate it in melsoft gx works 3, but how I can test the Modbus tcp/ip if I do not have an IP address for the plc  someone has ever communicate both software, gx works 3 an som modbus master software ??
  14. Been seeing a high failure rate on these PLC's on 2 of our processes. The control power is feed through a APC UPS to a 24VDC power supply to power the unit. Getting a hard fault where the OK LED comes on red and stays red. It never sequences through all the LED on power up. Tried the hard boot by holding in the reset button and applying power. Has anyone on else seen a high failure rate on this model PLC? TIA..
  15. I have a 1747-L30B SLC Brick and it is set to load from EEPROM on boot S:5/8, Error S:1/10, and Run S:1/12. I need to make changes to the program and then store it to EEPROM via "Comms>EEPROM>Store to EEPROM."  When I attempt to store the program with changes, it displays the message "Insufficient Memory Module Size." I assumed the EEPROM memory was maxed out, but I also uploaded the existing program currently stored to EEPROM, made no changes, and attempted storing it back to EEPROM and received the same message. Any advice?
  16. Hello, I am experiance a problem with a consumer tag staying stuck on. Producer and Consumer PLC are turned on. Information is getting transfered like it should. The Producer PLC gets powered off and the tag that is getting transfered over is ON before it gets powered down. When I check the tag in the Consumer PLC the consumer tag is still ON. Shouldnt the consumer tag go to the OFF state once the commincation has been lost?
  17. FX5U Modbus-TCP Server (Slave)

    Hello everybody. I need a solution for Modbus-TCP server on the PLC. With the FX3U it would work with the FX3U-ENET module. The internal interface of the FX5U should actually be able to work with the library of the FX3U (FX3GModbusTCPServer_GW2_V100) or not? Because a socket connection is now possible. I would be happy about suggestions. Dave
  18. Morning all, first off, when it comes to controls I’m pretty green so please bear with me.  I have a bunch of old Modicon TSX Compact plc controllers. Some of them have randomly stopped controlling the outputs, I replaced the output card (module? I don’t know what to call it), but no change. I don’t know if the program is messed up, or the main board or something else. I want to read the plc but don’t have and can’t find the software to do so. Any suggestions is greatly appreciated. 
  19. Hi Everyone, I have a small project where I need to detect temperature and smoke using Allen Bradley Micro820 PLC and send email when the temp is above or below a set limit. And since I'm new to PLC world I'm not quite sure which sensors would work with my plc model. It would be really helpful if anyone could guide me through and suggest any sensors appropriate for temperature (surrounding temp not liquid temp) and smoke.

  22. Motion Control

    Hi Everyone.   I have been tasked with changing out an older Flex Drive servo drive to a more modern Micro Flex drive in a machine that has an Omron CQM1H-CPU51 PLC.  I'm having a few issues but hope that i can gain some clarity around at least one of the hurdles Im facing from here. Biggest issue for me at this moment is My work hasn't yet purchased a programming lead for this PLC (or even the bits required to make one myself) but i have a feeling the control for the Servo is done via motion control in the PLC.  Question here is, if changing from one servo drive to another type, will the motion control code need to be updated to work with the new servo drive?  I have very limited experience with motion control itself at this stage so I'm a bit lost when it comes to these sort of details. Regards Kiwi_man82
  23. CP1E won't connect or run program

    Hi there! Today a CP1E-E10DR-D suddenly stopped working. RUN led was off and I couldn't connect to it via USB getting this error: "Selected port does not exist. Select proper port number from Change PLC dialog and press OK button", and automatic online function didn't work as well(it's not a cable/driver problem since I successfully connected to a CJ2 CPU using same cable and PC). Since I also tried to connect with the CPU outside the control cabinet with no success, I asume there is something wrong at hardware level.  My question is, have you ever faced something like this? My plan is to try to revive it somehow (maybe trying to locate any defective component in the PCBs or something). So I was just wondering if you have any advice in order to achieve it.  Thanks in advance!
  24. GX Works3 Projectlib Locked

    Hello, I have a problem that I need to solve in a PLC program has it's projectlib locked.  I work for a company that contracted a PLC programmer before my time to program their new version of their control cabinets. The company did not write any specific contract with the contractor and just relied on his work. The guy later delevered a buggy software that is kind of functional (the bugs came up at the commissioning after the guy was paid and now he refuses to help or to provide more consultations). I have as a task to freshen this up and make it work without bugs, the problem is that the Projectlib is locked and I cannot access the source code.  The only thing that I can changes that I can make to the code is to put some logical circuits between the I/O of the already existing function blocks, which solved some problems, but not all and it keeps one of the most important ones as well. Anyways, that's my story, so now my question is, is there and possible way of unlocking the projectlib? Any feedback would be highly appreciated. Thanks in advace!
  25. Hello, I'm new to setting up my controllers and communication between devices.  We wanted to see if using Modbus TCP/IP to communicate to a load bank was the right path for us.  I was able to configure my Micrologix 1400 controller Channel 1 for Modbus and set the data files.  I set up a read holding register 03 message, two write single register 06 messages and one write multiple registers 16.  I was able to read the data from the load bank, but I was unable to send any write commands.  I didn't get any errors in the messages.  I was able to send write commands through my pc to the load bank and it responded properly.  So I was thinking I must of missed something in my set up in the PLC. I'm attaching the PLC Program and the command set from the manufacturer.  Any help would be greatly appreciated.
