  1. Hi,I am connecting several computers and NS12 HMIs with a CJ2 PLC using EtherNet/IP protocol. And I would like to know the FINS Address (Net.Node.Unit) of the HMI and the computers. I suppose I need to fix their addresses using an IP Address Table. Right?? Anyway, I only know to do that with UDP, but I don't know how to do that under Ethernet/IP.Thank you.

  3. Net.Node.Unit on EtherNet/IP

    Hi, I am connecting several computers and NS12 HMIs with a CJ2 PLC using EtherNet/IP protocol. And I would like to know the FINS Address (Net.Node.Unit) of the HMI and the computers. I suppose I need to fix their addresses using an IP Address Table. Right?? Anyway, I only know to do that with UDP or TCP, but I don't know how to do that under Ethernet/IP. Thank you.
  4. Hello! I have one Controlllogix project that communicates with a modbus slave through modbus TCP, using a Prosoft module model MVI56-MNETR. Does anyone know what happens to the data polled in case the network fails? Do all variables go to zero or do they freeze in their last value (or something else entirely)? I couldn't find anything in the Prosoft manual. Thanks for any help!
  5. Hello There I need to set up communication PLC to PLC ( R08CPU to Fx5CPU) but i dont have the modbus library for  the R08  Does anyone have the library? or where can i get it? thank you.
  6. I am trying to use an Automation Direct Productivity P2000 to control a Kinetix 300 servo drive using Ethernet/IP.  I got the EIP working fine using Explicit Messaging.  The hardware enable and overtravel limits are hardwired ON.  The drive doesn't show any faults.  When I turn on the software ENABLE bit (bit 7 of byte 0 in the Output Assembly), the Ethernet communication stops.  Motionview continues to work, but if I disconnect and reconnect, it can't find the drive.  I have to physically power down the drive to reestablish Ethernet communication.  Once I power back up, EIP communication resumes with no issues. Any thoughts?  What am I missing?

  9. i am trying to communication my weintek HMI with Siemens Energy Meter PAC3200. I am using MODBUS TCP/IP Protocol but i am unable to read the data register of my energy meter. Somehow i got to read the 32bit data register but still unable to read the 64bit data register of my total KWHr Energy consumption. I have also attached the manual of my energy meter. Please guide how to read all the data registers of that energy meter. Please see the page 40 onwards for reference. The manual the about 7MB so i cannot attach the file. https://support.industry.siemens.com/cs/attachments/26504150/A5E01168664B-04_EN-US_122016_201612221316360495.pdf  
  10. Mitsubishi Fx5uc

    hello everyone, Im new with mitsubishi and  ive got a project with a Fx5uc but im stucked in communication protocol to communicate with a weintek HMI ive already tested easybuilder simulation with a modbus tcp ip symulator and it works but im completlely lost about mitsubishi, is there a way to communicate via Modbus TCP/IP? or which protocol would u recommend as i have to connect 2 drives as well. thank you in advance
  11. Hi all, after my complaing about my lack of network access in the workshop ive been tasked with fixing this so ive have some general questions about networking and concerning Ewons so this network will be used for connecting ewons to test products as well as general computer access the plan is to have 7 computer access points as well as 2 points to connect to product lines for testing my intial thoughts were to run 2 cables from our network to 2 routers, 4 computer access points and one line testing connection on 1 and 3 computer access points and one line testing connection on the other so first question is what type of ethernet cable should i use? i assume cat5 is fine, is it worth going for cat6 or is it just a waste of money? and should i be running crossover cable or straight through? do i need any specific routers or will anything do? will i be able to add splitters later down the line and be fine? or should i future proof a bit with more robust routers? my years of avoiding networking at uni has come back to haunt me i know the basics but thats all really thanks to anyone who can offer some usefull information i mention the Ewon units because ive been told that they need to be the only one on their connection to the network, although i dont know how true this is  
  12. Modbus fonction block error

    Hi everyone, first time posting here. I've got a problem with the Modbus MTCP-CP1L-Server fonction block. it worked fine for a good amount of time until i try to change an ethernet switch (not managed) on my network. at this moment the fonction block started to give me an error code (2211 ''unit is busy, can't execute''). So i put the old switch back again and I called Omron and they tell me to download Etherway and try to send some data to it but they can't do more. I did and BAM, it worked again. everything was fine for about a week and i was like, okay if etherway can ''solve my problem with the fonction block, i can put the new switch again, No I can't. It give me the same error, I try'd so many thing( put the old switch, everything that was possible in Etherway, change IP address, ethernet setting, reboot everything, connecting the unit direct to my PC. nothing can erase that error.  Unit is an CP1L-EM with built-in Ethernet port did someone had have the same problem, or have any idea that can help me ? thank. Sorry for my poor English, its not my first language.

  17. Hi all,  I am trying to configure an Fx3ge-24M PLC using GX-works 2. I can successfully connect to the PLC using the USB cable, however i am having trouble getting a connection via ethernet. I have attached a photo that contains the only ethernet configuration that i can find, what am i missing here? I'm new to GX works & mitsubishi PLCs.  
  18. We have an application using a Mitsubishi L02CPU-P with a built in ethernet module. At one time the TCP/IP interface became irresponsive and a hard reset was required. The device is configured for binary communication and works fine using a GOT therminal and also operates fine when queried from a GX Works application. During debugging of a custom MELSEC application the TCP/IP interface stopped responding and could no longer be located using GX Works and the GOT terminal also lost contact. The L02CPU-P continued running the control application, but could no longer be contacted. The only way to recover was using the L02CPU-P reset button. I have heard developers being restrictive using the TCP/IP interface remotely over VPN and unstable connection due to the risk of hanging the device and not being able to recover without a personal visit to the device. Any experience from L02CPU-P devices requiring hard reset to come "online" again? Or does it enter some default state due to some internal exception handling?
  19. Delta DVP12SE Modbus TCP Help

    I requested support on getting my DVP to talk to Factory IO for some cost-effective programming experience but the DVP is really poorly documented. The below wording and 2 pictures were all the support I got as I am not a business. The M codes are not listed in the ISPSoft help file and hard to track down, combined with things like "After the reception of the command is complete, bit8 in D1395 is ON" and then if I am reading input registers and holding coils but saving to a D word register how the heck do I convert the data into a useable boolean format for logic use??!! I have no been able to even get the DVP to read or write ANYTHING but I can use a modbus program to turn on the DVP's bits no problem so I know communication works. eg: F05 H500 will toggle coil Y0. The issue is when I try and use the DVP as the modbus client. From my laptop I can use these commands to modify Factory IO which is running as modbus server Slave ID 1: F02 H0000 H0009 (Read inputs 0 to 9) Tx: 00 02 00 00 00 06 01 02 00 00 00 0A, Rx: 00 02 00 00 00 05 01 02 02 C0 00 (In put 6 & 7 are on) F15 H0000 H0009 (force coils 0 to 9) Tx: 00 0F 00 00 00 09 01 0F 00 00 00 0A 02 00 00, Rx: 00 0F 00 00 00 06 01 0F 00 00 00 0A   But how the heck do I format the LD program to actually do those commands?

  20. Omron rs485 communication

    I am using OMRON CJ2M-CPU15 with SCU41-V1 communication module I want to establish communication (rs485 modbus) between omron and Schneider device for reading out electrical parameters. How I can do this? I could not find any manuals and this is becoming very hard for me. I want simply to read few registers from Schneider. Where do I set unit number, starting register, ending register, number of data? I was recently using Siemens and Unitronix and started working with Omron recenlty. Do you have any examples or manuals for this? Thanks in advance
  21. Hi to everybody. I'm beginner on Beckhoff so I'm having issues with connecting Beckhoff CX8090 and Weintek EMT3070a. I'm trying to use Beckhoff TwinCAT PLC Free Tag names to get data from CX8090.  I have followed instructions in EasyBuilderPro which are pretty straightforward. On side of HMI I need to select proper settings which should be: IP: 192.168.1.2, Port no.: 48898, ADS port: 801, AMS NetID: 192.168.1.2.1.1 I have succesfully imported all variables from my PLC program into the EasyBuilderPro. For testing I tried to create HMI just to see status of few inputs. I have no issues uploading program to HMI, but after startup I get message Device no response and communication is not working. On side of Beckhoff I have settings like this: AMS NetID: 192.168.1.2.1.1 Ethernet port X001: DHCP Ethernet port X101/102: IP: 192.168.1.2   I can access to CX using input ports X101/102 and also access to HMI through same connection. I have also tried to log on to windows CE on CX and tried to ping HMI and that also went ok. Also I have tried to add static route on TwinCAT to HMI with settings AMS NetID:192.168.1.3, IP:192.168.1.3 but again no connection. So physical connections are CX8090 X101 - > HMI, CX8090 X102 -> PC. From PC I can access both devices. I'm using TwinCAT 2. Can you tell me what I'm doing wrong?   Thank you
  22. My project is to read an RFID tag (ascii) with a Micrologix 1400, send the string to a PC using Ethernet/IP, lookup and compare in an Excel spreadsheet, and send back data (probably an integer) for the plc to use to control direction. I have to scan and compare an RFID tag to a list of 1400 possible part numbers, at different locations (more than 1 plc). I want the several PLCs to go to a single PC to make it easy to update when changes occur (on a weekly basis). Has anyone done anything like this? I'm assuming there will have to be some kind of vb or c+ application involved.   Thanks,  CK
  23. Connect PLC to Kepserver

    I have Delta 12SA2 PLC it has RS232 port and I have connected it to kepserver (by Modbus serial) and then factory IO Now my problem is that when I connect my PLC to kepserver the RS232 port becomes busy with the kepserver and not available in the ISPSoft and therefore I could not demonstrate factory io and my logic in run mode in the isp soft together like you do in your videos. My PLC don't have ethernet port but is there an option in kepserver or any way by which i can use the same serial port of the PLC in isp soft run mode and kepserver+factory io together so that I can simultaneously show the logic running in isp soft and application working in factory io to my students. I googled a lot and found some softwares which make virtual serial ports for a given serial port but they don't work and soon hang Please help me I am in a great need of it. Thanks in advance.
  24. Hello, From modbus, Im reading a HEX variable in the data register D0, as it is a 32 bit variable, the second part is saved in D1, then I get: D0: BE62 D1: 31D7 The value that I should obtain in float is -0.2208932 as I obtained setting  BE6231D7 in online Hex to float converter and this agree with what I'm reading on the flowmeter.  The problem is that when I try to change the data type from channel to Real on CX programmer I obtain a different value, also the registers are not sort in the proper way, instead they are sort inversely 31D7BE62, and obviusly the obtained value is completely different. Also instead of Hex, I want to display the decimal, or floating value, is there a way to do this? I'll attach some captures.    
  25. Hi everyone. I have project to use PLC Mitsubishi Q03UDECPU with QJ71EIP71 to connect with SICK FLEXI soft Ethernet/IP (FX0-GENT00030). I have check both manual but when I turn on Y0 (communication start) there are error code F100h on my QJ71EIP71 and I check that it can only use with produce/consume tag from PLC (such as OMRON, Allen Bradley) but for SICK device it can use only for assembly instance. Then I have use Ethernet/IP scanner (Molex) to read attribute (service code 72h) then I can read status from SICK but as I told before QJ71EIP71 can only communicate with tag-based. Then I have to ask everyone that 1. Are there method that can use QJ71EIP71 to communicate by use Assembly Instance? 2. Could I set consume tag name on FLEXI soft Designer? 3. Are there any protocol gateway device that match with these solutions?
