  1. CX Supervisor Modbus RTU

    Antagor posted a topic in CX-Supervisor

    Can CX Supervisor be used as modbus RTU master using RS232/RS485 or USB/RS485 converter to connect it to PLC or panelmeter or other modbus slave units and how? Any example? Thanks in advance Goran
  2. Hello, is there a way, to edit E5CC-T temperature controller internal program, using CP1L-EM PLC, connected to temperature controller via rs-485 communication? I can't find any information about doing it. I know that i cat change these programs, using CX-Thermo, but that is not an option. I need to do that, using only PLC..

  3. Omron 3G3HV Problem

    Woodpecker_Germny posted a topic in Omron

    Hello guys, I got a used Omron VFD from a friend. It was used in an industrial application. It works fine with the integrated panel. I would like to use it to run my drill press. I now try to control it by the so called 3 wire sequence (S1, S2, S3) for Start, Stop and forward/reverse. System does not work as expected, i. e. no reaction on the switches. I'm not sure if I have messed up the configuration of one of the n xxx parameters or if there is a HW problem. With SC open, there is no voltage at that pin (expecting 24Volts?!). Any thoughts? regards and thanks, Matthias   Current config: n001 = 4 n003 = 1 n004 = 0 n006 = F/R 052 = 0 n176 = rdy n177 = 1

  5. Modbus library for Siemens PLC's

    ola84 posted a topic in Siemens

    Hi.I would like to tell you about a modbus library I have made and recently released, for Siemens S7-1200 PLC's. I made concept that called Station block which is mapping of registers for one specific modbus rtu device. Station blocks can be made very quickly and can be easily be reused and combined with other station blocks. The library is free under the MIT-license and can be downloaded at github (link bellow). Please check it out, I would like to get some feedback on my work. https://github.com/olab84/rexhip/ An modbus rtu example: #mb_master_ctrl(hardware_id := "Local~CB_1241_(RS485)",                                 baud := 19200, // bps                                                mb_query := #mb_query );  #mb_query(mb_addr := #mb_addr,                                         mode := #mb_query.c.read.input_reg,                       data_addr := 13,                                            data_ptr := #resault_data_1);   #mb_query(mb_addr := #mb_addr,                                       mode := #mb_query.c.write.holding_reg,                       data_addr := 55,                                                  data_ptr := #resault_data_2); // - The library will take care of execute each query, one by one.  //    Add as many queries as need. (There no need of a state machine) // - Queries belonging to one device can be placed inside one FB, //   this FB can later easily be reused.      
  6.   A new free Modbus RTU/TCP slave simulator tool - Unslave - has been released. It is focused on simplicity, usability and ease of setup. Instead of a GUI it supports flexible JSON-based configuration, where you setup slaves like this: "slaves": {     "1": {         "isOnline": true,         "registers": {             "HR0": 1,             "HR10": "0x0A",             "C0": true,             "C999": {exception: 3}         }     } } This type of configuration has great benefits - you can easily switch between different setups by specifying a different configuration file: unslave.exe newConfig.json You can put the configuration under source control and track changes. Unslave lets you configure any number of slaves, setup values of every Modbus register, setup Modbus exceptions. In addition, Unslave displays and write to a file the logs of all communications on the link. This is very useful for debugging: 2017/06/06 17:21:54.310 - TRACE: Byte received: 1.

  7. Hello All,   I am would like to know how to send a bit from an excel file to an omron PLC through CX-server in order to confirm that I have communication and the excel file is open.   At the moment I am reading data from the PLC on the Excel file no problem but I don't know how to do it on the other way.   I am attaching the code I have written and the excel file. So the idea is having a cell with a 1 and reading this value as a bit ON on the PLC.   Thank you very much in advance I really  appreciate it. :)    
  8. Hello All,   I am having some issues with Excel while communicating with the Omron PLC. The Excel file is getting the data from the PLC and the macro doing what I want to do, but I am getting the following error messages when opening the excel file.   I am attaching the pictures of the messages and the code where debug send me.   Thank you very much in advance

  12. FX3U and FX5U Modbus RTU comparison

    Clear.Mind posted a topic in Mitsubishi

    Hello. I have tested different type of communication between by rs485 fx3u and fx5u. On fx3u side used fx3u-485-adp-mb. In case of N:N and Parallel Link fx5u is more comfortable than fx3u. But, modbus rtu not so good. I made 3 tests: 1)FX3u master with ADPRW function; ADPRW in fx3u supports wider count of modbus functions, most usefull for me is H17 (Read/Write multipleregisters). But when i send telegram to Fx5u with this function, fx5u fall in error (recieved unsupports serial com functions). i have checked instruction manual on ADPRW - FX5u doesn't support H17, only H03 and H10. For read/write from fx5u need to use 2 instructions on FX3u side. 2)FX5u master with ADPRW function; In this test ofcourse i tried use H17, but result was expected - error. 3)FX5u master with predifined protocol. In this test using H17 function on Fx5u side was successful. Conclusion: FX5u better use as master for modbus rtu communications via predifined protocols, and if it used as slave need remember that it doesn't support H17. I hope this information will usefull for sombody.

  18. CJ1W-TC102 Module Troubleshoots

    Antonio G posted a topic in CX-Programmer

    Hello Everyone. i'm in charge of a biodigester working with an old siemens plc, but today i recieved a cp1h-xa40dt-d with the CJ1W-TC102 temperature module. I need to migrate the programation of the siemens to the new one, but CX-Programmer isn´t so much familiar to me.  Basically, the old plc turns a mixer each 20, 30 and 45 minutes and i wanna make the same for the new one, adding a resistance for monitoring the temperature inside the digester. Do you have a program for me to check it out how it's done? I have the source code of siemens, idk i this could help.

  20. Hi Everyone! Where are my experts? I am undertaking a project at work. The project contains analog style motor positioning circuits (operational amplifiers, integrators, and other PI elements). Not that this is relevant to the post yet ;) .It's my first PLC project ever! I am using the Schneider M258 with SoMachine 4.1 The PLC is talking to SoMachine via Ethernet (obviously I have a router between the PLC and my pc).I can Login and run the first POU I created. It's a simple And logic circuit for now. I have a co worker (c programmer) agreeing to help me pass data from my PLC to a browser screen. Although he's not familiar with PLC he's quite skilled writing code. He has wrote a Modbus protocol which allows him to interpret Modbus commands on his desktop.   1) Do I Need any special hardware to pass the data out of the PLC into the Router then into his browser. 2) As a trial can I send him MODBUS commands regarding my AND circuit? 3) How do I create such a command? 4) Is it possible for him to send me Modbus commands to change variables inside my program? 5) Are there web browser "plug-ins" for this idea? Thanks for reading and hopefully all of you can help me answer some of these questions.        
  21. So just for anyone might interested, this past one year Omron had completely acquire Adept Robotics (California based robot manufacturer). The products acquired including all Delta Arms and SCARA (Quattro, Hornet, Cobra), also some Articulated / 6-axes robots (Viper), programmed with the ACE software. Other than that Adept also have Lynx AIV whose name is now changed to LD-Series. Aside from having an already established Robot Controller with by acquiring Adept, Omron also developing it's NJ CPU to control mechanical arms that can be user-built, with condition that it uses EtherCAT based Servo Control. The current version of NJ501-4XXX series PLC supports control over Delta Arms (3-axes + Rotation, 3-axes, 2-axes + Rotation, 2-axes), SCARA, and your usual Gantry XYZ+Rotation robot.   If anyone interest to discuss something about those do post here, or maybe create your own thread.

  24. Is CP1H with Ethernet option board (CP1W-CIF41) is capable to communicate More than one client? If yes what settings I need to be Done?  
  25. Hi all,   currently as part of a project I am trying to communicate between a Schneider M340 plc and an Allen Bradley micrologix processor. I am programming the M340 and the micrologix has been installed by another supplier. they have mapped the Modbus registers on their side and given me a spreadsheet with these.  I am able to read values with no issue but I cannot write values back.   i've included a screenshot or the read_var and write_var instructions I am using. I would really appreciate any help if anyone has any insight on this   Mark
