  1. 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
  2. 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     
  3. 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!

  5. 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.
  6. Selecting alternate POUs on FX5U

    I've to modify this program I wrote back in 2015 and modify the sequence in Seq100Bins. I'd like to work on a copy Seq101Bins during development and toggle between the two POUs. I can't find or remember how the various POUs are called. In most other systems I've used they'd be called from the MAIN / Program but the logic isn't in there. Can anyone jog my memory or correct my understanding?
  7. Hello all,   I am working on a batch computer for a concrete mixer, and the computer that was running the plant before has stopped functioning. It was an old PC running MS DOS. The code is encrypted and replacing it is not a cost effective option.   I therefore am looking into using a PLC to control this batch plant. I have a setup that was in progress by another employee who no longer works for us, it is a CLICK PLC from Automation Direct, and it is supposed to be paired with a EA9 T8CL touch screen HMI from the same company. I would like some advice on just some basics, I would greatly appreciate some input.   I essentially only have one input, and that is an analog scale, 0-20mA input. I have digital outputs for sand, gravel, cement powder, and a water meter for adding water to the mixture. I have one final output, an additive for reducing the required water in the concrete.   What I would like to create is a program that when it is told to start, looks at the scale, and if the scale is less than say 100 pounds, opens sand until it hits 1700 pounds (as an example), then turns it off. Then it turns on the gravel and adds that for another 1700 (again for example, all these are variable), turning the gravel off after. Next the cement, and so on. I don’t need someone to write the program for me, but can someone point me in the right direction on using an analog input to turn digital outputs on and off? Again, your help would be greatly appreciated.   Thanks for taking the time to read this long post.

  9. FX5U Shift Dword

    I read the max value from a encoder SD4502. In the label I have sign the SD4502 as double word. If the trigger ( X10) is high then the value is counting in SD4502.  If the trigger flange is going down I puls with DHCMOV the value from SD4502 to D0. Now I will storage this data like shifting but it is only working on 16 bit. Is any one that can help how I can solved for 32 bit? I have tryit with commando sfr, SFL or BSFR,BSFL and also SHR_E. measuring on belt.gx3
  10. FX5U CONNECTED TO KEYYENCE DL-EP1 ETHERNET/IP COMMUNICATION STANDARD 1. CAN I CONNECT ON THE ETHERNET PORT OF FX5U CPU OR NEED EXPAND MODUL? 2. IF CONNECTED, WHAT STANDARDS TO USE AND HOW SETTINGS? THANKS EVERYONE!   DL-EP1.pdf
  11. I'm modifying an STL program I wrote some years ago. I need to split an STL sequence (to let the first part restart while the second part runs on). The original POU runs from STL S100 to STL S138 in steps of 2 and the STL sequence ends in a RETSTL instruction. The modified program ends at STL S134 with a RETSTL instruction followed by the new sequence which runs from STL S140 to STL S146 and ends with another RETSTL. This modification causes the PLC to fault with error code 33E7 - Program structure error. Can anyone explain what's causing the error and suggest a fix or workaround? Many thanks.

  14. Werking PID regeling

    Beste allen,  Voor een temperatuurregeling om een watertank om product op de juiste temperatuur te krijgen en te houden voor een aantal minuten. Wil ik een PID regeling toepassen, want volgens mij is dit de beste methode om zoiets toe te passen Of heb ik dit verkeerd?  Een situatie schets is: Er komt product in een watertank. Dit wordt doormiddel van water en stoom verwarmt naar 120 graden. Hier 20 min gehouden en dan terug gekoeld naar 30 graden.  Hoe kan ik het beste mijn PID regeling maken om zo snel mogelijk op de 120 graden te komen en daar stabiel te laten blijven? Bij het afkoelen mag het Delta T verschil niet groter zijn dan 50 graden anders gaat het product kapot.  Ik heb wel wat ervaring met het programmeren van plc's, maar nog nooit een PID regelkring toegepast.  Vandaar mijn vraag hoe werkt zo'n regeling precies. Ik heb wel wat filmpjes bekeken hoe je het kan programmeren. Maar voor mij is het niet duidelijk wat er nauw precies gedaan werd en waarom. Kunnen jullie mij dit  uitleggen, zodat ik het begrijpen ga?   Er wordt gebruik gemaakt van een fx5u plc, geprogrammeerd in gx works 3 en een got 1000 scherm om de data te lezen en te schrijven.  Warm water is een open/dicht klep. Koud water en stoom zitten een regelklep van 4 - 20ma in het leidingwerk.  Ik wacht in spanning af.    Groeten A. J    
  15. I'm making some changes to a project at a customer's site using all the same software, etc., that I created it in. I only use GX3 for this project so I'm not an expert. When I try to transfer I get ... ... immediately followed by ... Now I've got a red ERR light, P.RUN is blinking and we're out of production for a few hours. The error flags M8060 to M8069 are all zero. It may be related to two function blocks at the end of the transfer but the F4 Rebuild All function works fine. Can anyone help? Thanks!
  16. Hello Guys, I have a problem with my Screenbuttons, if i push them, my drive moves only an Impulse. I see on the Simple-Motion Module that the Signal is during pushing the screenbutton is active, but the Axis moves only an Impulse. In example M400 is for drive the 2nd Axis to the right side and M405 for the left side. My Hardware is: FX5U, GOT2000 (GT2505HS-VTBD)

  19. FX5U and SEW inverter over profibus

    Hi, I am not very experienced with PLC's. Now I should control a few SEW movitrac inverters with a profibus connection. The PLC is an FX5U with an FX5U-DP-M communication module. I managed to get the network settings up and running. But I don't know how to make a program to control them. Would anyone have a sample program that could help me to get strarted?
  20. I did a lot of research for being able to control my Mitsubishi FX-5U PLC. I want to control it over network using SLMP with 3E frame messaging, but I am unable to understand the message frame. I am referring this manual. But despite spending days I haven't been able to understand how to control the PLC using SLMP. I understand that if I use this message frame, I will be able to read data on D200 register, and it does work successfully. 50 00 00 FF FF 03 00 0C 00 10 00 01 04 00 00 C8 00 00 A8 01 00 But, I just don't understand, how to access and control the devices on X and Y. Lets say I have to read data from all inputs (X) or write data to all/few output (Y) at once. I tried resolving this issue by trying to write to outputs, Y1 and Y2, and set them to high, but it doesn't work (Below frame is in ASCII format) 50 00 00 FF FF 03 00 0D 00 00 10 14 01 00 01 Y* 00 00 01 00 02 11 I know I am doing it wrong, so want to know really what am I doing wrong
  21. FX5U Modbus communication

    Hello, It is necessary to manage 34 inverters via serial communication RS485. If a Modbus protocol is used according to the documentation, only one RS485 channel can be master. Then the maximum number of inverters will be 32. Can anyone share their experience on this case? Thanks in advance to all those who participated!
  22. Using HOURM as Retentive Counter

    Hello Guys,  is someone using HOURM as a Retentive Counter ? I Tried it but i have no success. like this one: HOURM( Betriebsstundenzaehler_ein , 700, Betriebsstundenzaehler , Platzhalter1 ); I'm using FX5U. Our old Programm was written in Ladder.    
  23. I am new to PLC programing, I want to connect FX5U and MR-JE-_C via CC-link. When I connect FX5U and MR-JE-_C directly everything works, but when I connect them in HUB (I need to use HUB because later I want to connect GOT2000) I am getting error 86.1(network communication error) on amplifier. Previously I set up IPs shown on pictures below, now sometimes works, sometime doesn't work and sometimes works for 30 seconds and I get same error. Did I miss something? I don't know what to try else.  
  24.   Good afternoon, dear specialists. Recently, only without preparation, I began to set up communication between the scada and the PLC. The problem is that RSLINX LITE (v3.90.01 CPR 9 SR9) sees both PLCs on the network, but one of them gives a problem with reading data, or rather, the data monitor does not load at all (or shows a red cross (which means there is no physical connection to the PLC)). But it responds perfectly = 1ms. Nearby is an old PC with an old RSLINX LITE (v2.41.00) that perfectly reads data from both PLCs. What is the problem? why doesn't the more recent program read the data? There is an even older PC on Windows XP on the Intouch scad, via OPC the "SMC" application also reads data without problems New PC:                                               Old PC:                                                still the third ancient PC: Windows 10                                         Windows 7                                            Windows XP RSLINX LITE v3.90                             RSLINX LITE v 2.41                             SMC (intouch) Status Not working                              Status Working                                      Status Workinп It was also connected via the "Ethernet" and "Ethernet / IP" drivers. I directly connected a new PC to the PLC and set up only one connection, still the result is negative. I would be grateful for any help! If I apologize for my English, I did it through a translator.    
  25. Dear Mr. PLC forum members, I am brand new to the world of PLC’s and I am looking for advice on PLC platform selection for a device prototype. The proposed PLC is for a “smart” hydroponic system. Please see system I/O and other parameters below. Parameter 1: Price - I am self-funding this so price of PLC and software is important. Happy to spend ~$2000 for PLC; I/O cards and related hardware. Total prototype cost is around $15,000 including PLC. Parameter 2: Availability & Support in Australia. Parameter 3:Newbie Friendly: I intend to code the PLC myself and have never coded a thing in my life before.  Parameter 4:Discrete Outputs: 11; Discrete Inputs: 0; Analog Outputs: 2-3; Analog Inputs: 9  Parameter 5: Capability to extend to IOT for remote access control and monitoring (via cellular or wifi router)   As you can see, this is a relatively simple automation project. All my research seems to point to Automation Direct’s BRX PLC but I just wanted to get some suggestions and feedback before purchasing. Anything else that might suit my needs? Any insight would be greatly appreciated. Bruce
