  1. Hello everyone,   I'm seeking recommendations for training programs or resources focused on building control panels. I have a basic understanding but want to enhance my skills in design, wiring, components, safety, and troubleshooting.   If you have attended any reputable hands-on training programs or know of online courses, I would greatly appreciate your suggestions. Any personal experiences or tips are also welcome.   Thank you for your assistance!   Best regards,
  2. Hi guys, hoping for some help with a module problem I am having. We have not long started using GX Works 3 and Fx5's. In the UK we are having problems getting Fx5-4ad modules, so having asked our local distributor for an alternative he has told us we can use a Fx5-cnv-bus and an Fx3-4ad. Having read the manuals from cover to cover I still cant sort the problem. Picture one shows how the modules are depicted in the manual and also in hardware. Picture two is how GXW3 lets me put the modules together. Picture three shows GXW3 will not allow me to put the modules together as should be. Picture four shows the error message I am getting, also the error light is flashing on the Fx5. Pulling my hair out guys, and at my age need all I've got. Any help much appreciated. Steve.          
  3. 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.  
  4. 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.      
  5. 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.
  6. 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.
  7. CP1L Serial TXD Data Error

    Hi, I have a problem with serial communication (no protocol) using rs485 module, the received data is error. I'm using CP1L CPU, CP1W-CIF11 module as transmitter, and USB to RS485 converter as receiver. When I check the received data on PC, it's incorrect (bit error?). I just send 2 bytes data, 0x61 ('a') and 0x62 ('b'). My configuration: DIP switch CPU 4 = off, DIP switch CIF11 1 to 6 = on,on,on,off,off,off, 2 wire RS485. (I also attached the program and settings) https://postimg.cc/gallery/pr293Jc   Could you help me to solve this problem? Thanks   Program and Settings:     Result:

  9. 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.

  14. 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
  15. Modbus Tcp Ip

    Hi everyone I'm new programming this plc, I need to create a Modbus table with some Modbus adrres, my plc needs to act like a slave and a SCADA gonna send me some data, but I don't know how to set up it,  the manual talks about SP.SOCOPEN  but I don't understand how it works, and how to set up it. could someone help me     
  16. Dear all, I have an Omron inverter 3G3TC-AB004, which apparently there is not much information about it online. I have successfully connected this inverter with Modbus, and able to change some of its parameters from Modbus Poll, yet I still haven't found the address for the Start and Speed Command. I've tried to set the frequency from modbus but unfortunately it's a read only register. Is it possible to control this inverter from modbus or it's only useful for monitoring the inverter status? Thanks in advance.  
  17. 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.

  18. 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!
  19. Device Memory Mismatch

    Hi guys I have a mismatch in my Device data and I do not know why this is mismatched, can someone give me a indication of where to adjust it or view where it is assigned?   Kind Regards Morne
  20. Hello, I am rather unexperienced with PLC's but have some experience. I Currently have 2 Lexium ILS1 motors which we want connected over RS485.  I have read a couple of manuals. I have found which format they want to receive their data and what the pinout of their pre assmbled cable is (which hasn't been delivered yet).  I am currently unsure about a couple of things. The wiring the formatting of my data i'm sending, and the program.   The pictured below show my motor (which runs when i connect it to the PC and run it using the software provided so it is in working order) and the PLC with option port (which i used to transmit data to another PLC, so again i can't blame the hardware for being at fault here). However when i connect the cable and try to communicated I Don't see the LED light up. I followed Lexiums guide on which pins to use. But i figured for good form i might include these pictures to be certain hardware is correct.      Finally here is my program. I followed Omrons quick start instructions. But: my send ready flags never become high and the way data has to be formatted for these lexiums seems very labour intensive. But this is how i understood it needed to be done. Am i doing something (or a lot) wrong here?      I hope someone can help me out here! If any further information is needed i'll do my best to provide it.   Kind regards.
  21. File Transfer Protocol

    Hello I have a FX5U PLC that is performing some data logging (D-reg and Bit) through the CPU module logging configuration tool, sample time of 5 minutes. Currently the client is physically swapping the SD cards to retrieve the data. I wish to set up a File Transfer Protocol function to transfer the logging data to the C drive of a local PC. They will be connected via ethernet cable through a network switch but independent of any other networks or internet. Desired function of FTP: 1.      Data transfer every 24 hours 2.      Confirm SD card not in use (either pause logging function or carry out in between 5 min samples) 3.      Read logging data from SD card 4.      Write data to local drive on PC 5.      Delete transferred files from SD card to leave capacity for further logging operations 6.      Data logging instruction file (.llp) must be left on SD card 7.      Recommence data logging function I have configured the PLC as FTP Server and managed to view the contents of the SD card through windows file explorer on laptop with limited success (connection is intermittent and when access is possible, it does not always show updated/latest SD card contents) Is it possible to achieve the automated FTP using Mitsubishi and Windows software or do I need 3rd party software as well? Any advice on this would be hugely appreciated.   Many thanks.

  24. Here is a post that we recently completed on the Automation Direct USB to RS485 Adapter.  The USB-485M is a 2-wire USB to RS-485 serial communication adapter for RS485 use. It does not require an external power supply or complicated configuration. It has a Type A (plug) USB connector for the computer side and a universal female RJ45/RJ12 modular connector. This will accept RJ12 and RJ45 plugs.  The USB-485M supports multiple baud rates and is USB V2.0 Compliant. Read the rest of the post...
