  1. Axis ON Problem

    I have already used this module and the function blocks. However, only the function blocks in the POU “Axis_1_Manager” and only with MR-J4-B. But it should also work with MR-JE. I would delete the other POU's. What does the Axis monitor say about the axis? Attached is a demo project for FX5-40SSC and MR-J4. I made some FB myself.   FX5U_4SSC_MRJ4_ORAG_Demo_v0.4.gx3
  2. MR-J4-A operation mode alarm E6.1

    I know, I'm late. But maybe it will help in the future. You can also set all hardware inputs in this dialog. This is helpul for "servo-on" and position limits to.  
  3. Mitsubish FR-A8AP resistance across terminals

    Hello I'm not sure if I understand your question correctly. If you measure the resistances while the encoder is connected and supplied with voltage, then no reasonable value can be measured. If the encoder is connected but not supplied with voltage, it can also be the encoder that leads to these measurements. Depending on whether track A or track B or both or neither is active, this could lead to different resistance values. BR, Dave
  4. How can i limit MRJ4 servo load?

    Hi, If the torque limits should be fixed, the parameters PA11/12 can be used. If the limit is reached, the TLC output is set. However, the torque limit could also be set via an analogue input. You can find all the information in the MR-J4-A manual: External Link I wish you success Dave
  5. GOT-Barcode reader

    Sorry late, USB barcode scanner works fine with GOT 2000 at least with GT25 / GT27
  6. How to check for spare point from PLC program?

    Same with GX Works3 or use "Cross Reference"
  7. Retentive Timer on GX Works 3

    R64P is the power supply. OK, I'm late but I've already taken this screenshot. Maybe it helps someone else. Dave
  8. FX5U Modbus-TCP Server (Slave)

    Just to clarify, with Modbus the slave is called the server. This never sends anything on its own. The client (master) reads and writes data provided by the server. Here is an example in which the holding registers 40000..40033 are mapped to the device D1..D34. Also register 42000..42059 to D100..D159. A client can than write and read only in these areas. You can configure this freely according to your needs. For testing I always use the tool QmodMaster a free master for MB-TCP and RTU Dave Settings Test: One important thing: the slave ID / slave address must be 255. (See screenshot) This could be your problem.   FX5U_MB-TCP-Server.gx3
  9. 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
  10. FX5U Modbus-TCP Server (Slave)

    For a step by step solution for MB-TCP Server (Slave): - Download the manual JY997D56101 to e-manual viewer. - Put this site-ID in the search field of the "e-maual viewer" and select PAGE in Filter section. JY997D56101-BF If you don't change anything in the settings here:  JY997D56101-C3.P2, all registers of the PLC are available on Modbus. If this is not what you want, delete the unwanted registers there: If that doesn't help you, describe your problem in more detail. Dave  
  11. FR-A740

    Hi I think the option module FR-A7AN give you two more analog outputs. (4..20 mA) There may be other modules as well Greetings Dave
  12. serial input string

    I don't speak ladder but in ST I would do it like this. Maybe that helps. Greetings Dave P.S. If you need INT not REAL (with one decimal place) you can add this at the end. nResult := REAL_TO_INT(rResult * 10.0);
  13. Mitsubishi FX5 read/write from PC with nodejs

    Hi DavidOtt I have made tests with this Node for Node Red. works find with FX5U. Maybe you can read the code behind this Node? node-red-contrib-mcprotocol (node) - Node-RED (nodered.org) I wish you success Dave
  14. Predefined Protocol Q/LCPU to Slow

    Yes, I work for Omni Ray AG which is the representative of Mitsubishi Electric Factory Automation in Switzerland. Unfortunately, I'm more likely to get help here than at the European headquarters. And you?
  15. Hello, everyone I have to query a SICK distance sensor from an L26CPU via the onboard Ethernet interface. I have created a simple protocol which I start with the function block SP_ECPRTCL. Unfortunately it takes at least 25ms until the next telegram is started. The sensor responds within approx. 1.5ms. Does anyone know whether that works faster or is that a limitation when using the predefined protocols? Sensor manual:  OD5000, 8021391 (sick.com)  (Chapter 7.4) I am grateful for all the hints. Thanks and regards Dave SICK_Protocol.tpc Messaufbau_vTest.gxw
  16. Predefined Protocol Q/LCPU to Slow

    Hi DWIM Thanks for your answer. My L-CPU doesn't have much to do. Cycle time approx. 2.5ms. It's more of a problem with the predefined protocol. I made communication with many stations with FX5U and Ethernet / IP - Module. With 30 slaves from Moxa (ioLogik E1214) Unfortunately I can't remember the total transmission time. Really fast communication is possible with iQ-R and CCLINK IE Field, but it is very expensive.
  17. GX Works 2, Simple ladder, two dimensional array

    Thank you, good suggestion. I just have to find out how it works. I never use ladder certainly not inline ST ..
  18. Hi there I have to use simple ladder in GX Works 2 with System-Q. I need to handle a two dimensional array. That seems not to work because I became a Error message. (Screenshot) abTest[1] works, abTest2[1,2] doesn't In ST everything works fine. Thank you in advance
  19. FX5U Modbus-TCP Server (Slave)

    What do you mean by your message? With the newer Firmware for FX5U, Modbus-TCP Server is natively available. To download the demo project above, you have to be registered on this site.
  20. FX5U Modbus-TCP Server (Slave)

    Update: Modbus-TCP Server functionality is now possible without any FB. (Firmware 1.60 an above). All the necessary settings are now located in the parameter section.
  21. Hi Clearmind.

    For a customer we need the confirmation of the Russian EAC approval.
    It is about iQ-R and GOT2000. Do you know this EAC? Is this supported by Mitsusbishi? Thanks already for an answer. All the best Dave

  22. Hello everybody. I am looking for a solution for an FX3U with mounted FX3U-ENET on the right, to communicate with an FX3GE. I need to read and write some device in the FX3GE from the FX3U. I have made a paired connection in the FX3U-ENET module and made an MC connection in the FX3G. But how can I send or read data? Is there another solution apart from the MC-Protocoll? I am using GXW2 version 1.551z. Languages: ST or FBD Thank you in advance Dave
  23. Connecting FX3U-ENET with FX3GE over Ethernet

    Finally it works great! FX3U Read / Write D-Register from Slave FX3GE.
  24. Connecting FX3U-ENET with FX3GE over Ethernet

    Hi Gambit Can you give me a name of the library, because I don't find anything suitable. I have found: " FX Series - GX Works2 - Ethernet - EthernetFX3FixedBuffer_GW2_V101 " but I think that's not the right way. In this moment I found  "EthernetFX3MC_GW2_V100" maybe it is what I need. I will inform you here.
  25. Create a *.csv file

    Which CPU do you use? With L-series or System-Q with SD card, you can set up a logging and save as CSV on the SD card. With the FTP server on the CPU switched on, an FTP client should then be able to be fetch the file. I have never tried this and therefore I don't know how to access the SD card via FTP  . But this solution would be free
