  1. Hello hello, may I have your experienced advice with GXworks3? I have to write an RS485 protocol into the FX5UC mitsubishi PLC with GXworks3. I have a guide of the protocol so I have all the information. I attached an image from Section 6.7 of the FX5UC serial communication guide (one of the GXworks3 e-manuals) and it shows a message that is quite similar to mine. If I am not mistaken, a single RS2 ladder logic block will do that full message. The other image shows some PLC configuration where I can define those headers and terminators, and sumcheck. Fairly straight forward.   Here's where it gets a bit foggy. For my needs: Each character of the message (DLE is a character, STX is a character, data is treated as all one character...) needs a start bit, 8 data bits, odd parity, and one stop bit. So DLE needs start bit, parity, stop bit, so does STX, and my data chunk, etc. Correct me if I am wrong, but I'll probably have to turn off header and terminator in the PLC config, and send those characters individually so the parity and stop bits are added. But what about that start bit? The config image I sent shows that I have no start bit options. I can't just add a header that is 1 bit (also correct me if I am wrong). It seems to want to send a full 8 bit header even if its all zeros and a 1 (00000001) which won't work for timing reasons. And because I will have to send each character individually, then I have to generate my own CRC bytes. But maybe I can handle that if you show me how to do some manipulations to add in my start bit.   So to start off, how would I add a start bit using ladder logic? The RS2 command does not seem to give me that type of access. Section 6.7 of the FX5UC serial communication guide (one of the GXworks3 e-manuals) nicely explains how to do the communications over RS485 but again, no start bit or CRC options.
  2. CC-Link AD/DA IQ-R

    Hello everyone, I am studying Mitsubishi R-Series PLC with GXwork3. I don't really understand communication using CC-Link. Below I have the module configuration that I use. My hope is that the Digital operation value of the AI module is stored at addresses D0-D32. and I sent AO to address D100-D132.  can someone guide me to give me an example of how to set parameters and create a program. thanks you
  3. Hi all ,    I've a simple question. But it's a problem that makes my job difficult. How can i see full name of this labels. Without double-clicking or hovering the mouse cursor over it. I have to keep clicking while checking the program.This steals my time. And sometimes I can accidentally change it when I click...  
  4. gx works 3 how to use only 1 adprw for reading and writing paramets Modbus RTU? I dont know many about this, but i understood it like when you push control commands vfd going revers or stop etc. And maybe at the same time adprw reads its parametrs.  Please help. It woulde be nice if there will be attached photo or visual real example

  6. 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?
  7. Hello all. First time post in this forum. I am hoping someone here can offer some advice or a solution to a problem I am having. I have a Modbus water meter from chinese that connected to my FX5U with ADPRW Instruction, but i have a problem. The cumulative flow from water meter is a 4-byte hexadecimal number, with the high bit first and the low bit last. I want the output from the PLC is real number FLOAT. can someone in this forum help me to combine 2 different WORD and create a single FLOAT. Here I Attached document from water meter.   Thank you, Modbus协议英文Modbus water meter communication protocol.pdf
  8. Simulation of FX5 in GX Works3.

    Hello gentlemen. I am working in a company that makes SCADA software, and needed to do reading/writing tests on MitsubishiPLC's, In this case I needed to do tests on FX2, FX3 and FX5. I saw that Mitsubishi makes available the GXWorks 3 software that is possible to do simulations of FX5 and FX5u in it, but I can't connect in any way to the PLC being simulated on the company network. I put the correct IP in the ModuleParameter\EthernetPort configurations, I write a simple read/write program in ladder, and I use Star Simulation, but when I try to ping the PLC, I can't find it, much less talk to it via VisualStudio . How can I connect this PLC that is being simulated in GX Works3 in an external program?
  9. Hello Everyone, I hope everyone is always given healthy I'm using an FX5UC-32MT/DSS plc, and I see it has a built-in CC-Link IE Field Basic. I want the plc to communicate with the remote output module. I have done hardware settings on NZ2GFCF1-32T, with station no. 1, rear SW function AUTO PRM = ON, in software settings, on my CC-Link IEFB Configuration the "Detect Now" feature NZ2GFCF1-32T is not detected in CC-Link IEFB Configuration, and I am using CC-Link IEFB Module (General) for NZ2GFCF1-32T. LED for DLINK and LED ERR OFF FX5U IP : 192.168.135.20 (master) IP NZ2GFCF1-32T : 192.168.135.1 Can the Build-In Feature on the PLC communicate with the NZ2GFCF1-32T? Do I need to add a module as master? Best Regard
  10. CC Link Settings

    Hello, I have a project where i will be adding a new R04CPU to an existing CCLink network via RJ61BT11. The existing network has 5 stations and the Master module is a QJ61BT11N.  I am new to CCLink and have tried learning more through the manuals but i still have unanswered questions i cant seem to find answers to.  By adding this RJ61BT11 to the existing network as station 6, I will have to configure the settings on the RO4CPU for the RJ61BT11, aswell as on the QCPU for the master QJ61BT11N. Is this correct? By adding this to the network using the CCLink Configuration Tool in GXWorks2, I get the error (The Refresh Device settings are overlapping). Its referring to the Remote Inputs/Ouputs and the Remote Registers. How do I know what to set these ranges to?  If these ranges change, Will this effect the current program that is referencing certain inputs/outputs and addresses? Or will it only add to the end of the existing range, therefore leaving the addresses used intact? Im going to attach an image of  the Current, Existing settings (No implementation of the RJ61BT11) that are working on the machine. My goal is to implement the new R04 PLC to handle a vision application and transfer data between the main machine (QPLC), such as recipe data, and vision results. Any help would be greatly appreciated.
  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.
  12. Hi, I am using IQ-R Series "R16ENCPU" With Inbuild CC-LINK IE FIELD "RJ71EN71" and attached CC-LINK "RJ61BT11". Problem is, Even though my remote IO cards are in Online connected with masters, I cannot able to On/OFF Remote Device station IOs in CC-Link IE FIELD network. But CC-Link Normal is working fine. Refresh settings and Network Config Settings are done, Below attached the pics for reference. I cannot able to find the problem, Can anyone help me in this.  
  13. Configure two HMIs

    Hi! I'm interested, is it possible to configure a second GOT HMI on an existing machine? The current HMI is on CC-Link IE field communication on a net switch.  (It's just an idea for upgrading the production)
  14. I need to know what kind of connector/cables i can use for my network: Topology, ( all on one switch): * Ethernet: FX5U, GOT, Safety PLC (WS0-GETH00200) * CC-Link: 2X  Inverters FR-A840-00023 Does this systeem needs the RJ45 4wired  or  8wired cables/connector?
  15. GX Works 3 Remote IO setup

    Hello. I am told that the use of a remotehead IO-module demands that a separate project is necessary. Is this true? I am using a R32EN cpu.   EDIT: Just received word that it's because it's necessary for hotswap. Cheers // RI
  16. CCLINK program problem

    Hello everyone, I want to ask,, Does address mapping use this concept to do "remote i / o station" can be done? following the network parameter settings for CCLink and I tried to program with this ladder, is that correct?  
  17. I simply want to create a function that measures how long the machine has been running/functioning. I see the option to create the OUT T function, but that allows me at max to count up to 9999. Do I have to create some registers to continuously store this data?  Can I not just have it count up freely?  I have a couple other functions I need to run off of this further on, but this is the foremost issue. Any ideas? Thanks so much in advance.
  18. 1ms TON and TOF GX Works 3 FX5U

    Hi everyone I'm new to FX5U, 'cause I previously used Q-series PLC. So, is there any possibility to make on delay timer with 1ms PT?
  19. Hello everyone! Is there possibility to read words e.g. Name of alarm from the csv file or another file and save it in the PLC memory for further processing? It would be the best if the solution will matches to FX5 and IQ-R/F but it can be also for any of them. Thanks for help :)
  20. GX Work3

    Good day everyone. I like to know if anyone has worked with GXWork3 yet and what their view is on it?
  21. Combine 2 Machines with CC-Link

    I would like to combine two existing machines with CC-Link. Each machine has a QJ61BT11N set up as its Master Station. The larger machine has 26 remote I/O and 4 remote devices. The smaller machine has 1 remote device (see the attachment). Each are already programmed and running. The larger machine has HMIs that I would like add screens to in order to control the smaller machine as well. The smaller machine would basically just need to send and receive a handful of signals... start, stop, manual, origin, e-stop, fire specific outputs, etc. What would be the best way(s) or simplest way(s) to connect and communicate between these machines? I am open to any advice and ideas. Thank you Machine_Addition_Via_CCLINK.bmp
