  1. Hey everyone, I have a CJ1M PLC with a CJ1W-SCU21-V1 serial card. It is unit 6 and I am using port 1. I have bit 1659.06 ((1500 + 25 * Unit #) +9, bit 6) as "characters in buffer" but it never comes on (data is being received through the port successfully). It is on No-Protocol mode. Does anyone have any ideas as to how I can detect data in the buffer?
  2. 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. Serial comm with FX1N PLC

    I need to communicate with a Mitsubishi PLC using Matlab. To do that, I open a serial communication with the appropiate parameters (7,e,1,9600), and write an ASCII message based on the manual I have (attached). I have tried examples as the one in the attached image. The response starts with a 6, that is, the ASCII number for ACK, so something must be working. But the rest of the response is junk (149, 149, 149...), although its length depends on the input length (if I add terminator, the response is longer, and so on). I am completely stuck. Some information that might be helpful: I am using a Serial to USB converter that I have used successfully with other PLC (which used Modbus, so everything was easier) There's a VB application (of which I don't have the code) that is able to connect to the PLC (I need to connect directly without using this intermediate app). I have decompiled it trying to get some info, but was just able to confirm the 7,e,1,9600 parameters, since the rest of the code is too mangled to analyze The attached manual was sent to me by the guy who designed the PLC and its ladder code, so I guess it is the correct one I have tried the echo mode (TT) to no avail, response is always the same I have some doubts regarding the reading of a value (see attached image). Why is there a second message from the PC? Shouldn't I just need to read the response? GX Developer tells me that the address D8120 (which is supposed to define the comm format and protocol) contains a 0, which seems weird. Any help or hint would be greatly appreciated.

  4. 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.
  5. 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?
  6. Can anyone explain to me what this would mean in a COP instruction? Source: #N[N187:4]:[N187:5] Dest: #N[N187:1]:0 Length: 20 I am doing a PLC5 conversion to rslogix5000 and some (most) of it has been a nightmare -.-
  7. 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
  8. Hi All, I've some problems after converting a cqm1-cpu41 program to a cj2m unit. I am still trying to identify all problems  but the most annoing at this moment is the following. This cpu is connected to a proface HMI, and commands the screens that are shown,  through D1. I am keep getting screen #9 ("press reset"). if i press and hold ALARM_RESET (0.07) and the timer hits, I get the main screen that i want.But after releasing ALARM_RESET (0.07) screen #9 is back again (so that value is wriiten in D1)   This is a snippit of the converted program (exactly the same as the old program) There isn't any other code writing #9 in D1.  The strange thing is that line 210 is doing exactly that ( IF NOT ALARM_RESET (0.07) -> MOv #9 to D1 ) what is see, but how in earth did this work in the old CQM1 unit ? I suspect something with cycle time ? Maybe in the old unit line 217 was executed later and #A was written in D1 'over' the #9. Anyone has some thoughts on this ? Thanks in advance  Jeroen  
  9. 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  
  10. Hello guys, I am very new at this. I am trying to make a Schneider PLC (TM251MESE) to send some serial commands (485)  to a integrated stepper motor from Automation Direct (STR-MTRD-17030RE, but I am lost. The driver has been program to receive the SCL commands. But not quite sure how to send those from the plc. Im using SoMachine V 4.2 Have any of you done anything similar? Any example will be greatly appreciated.  Thanks

  12. Hello, Can anyone tell me what types of Ethernet/IP device the  QJ71EIP71 can be configured as? Explicit message server, explicit message client, I/O adapter and/or I/O scanner? I'm having trouble finding this information in the manual: https://eu3a.mitsubishielectric.com/fa/en/dl/12484/SH(NA)-081157ENG-B.pdf
  13. 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.  
  14. 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?
  15. 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
  16. Hello. I am trying to make a serial RS 232C connection between Schneider Magelis HMIGXU3512 and Omron PLC CP1E. However, there seems to be a communication problems between both of the equipment. I am using cable XBT Z9740 for the serial communication cable. The format used is 8.2.N for both equipment. The baud rate is 115200. No Flow Rate is choose. Anyone can help with this kind of problems?
  17. I am working on  calculating a checksum value for a command that is to be sent from an Allen-Bradley CompactLogix PLC to a Mass flow controller. An example of a command is the following: "@@@022SX!20.00;CHECKSUM".  1. The checksum is the sum of every characters' ASCII code value (starting from character 3).  2.Then this sum (which would be in decimal format) has to be converted to HexaDecimal 3. Finally, the last two characters of the result have to be extracted and that would be the value of the checksum.  (For Ex: the value of every individual characters' ASCII code (starting from point 3) of the above command is 715. in HexaDecimal, 715 = 2CB. So , the value of the checksum for this command would be 2CB) I got to the point where i found the sum of ASCII code. Any idea on how to convert that to  a HexaDecimal and then convert that HexaDecimal to a string so that I could concatenate it to the command string??   
  18. 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
  19. 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.
  20. Conversion from A to Q

    Good Evening everyone, I do realise that this has possibly been done before but quite a few years ago and the links no longer seem to work or links to Mitsi pages that are in Japanese, so please excuse me. I have soem A series PLC kit that needs replacing and I have bought all new Q series stuff to replace(where possible). I have been languishing a little on this project now for a few months but need to get moving. I purchased a GOT HMI and got a good deal on the HMI and the complete Mitsubishi Software Suite the local Mitsi guru said that was all I needed to get the job done. But afetr delving into what came inthe box it seems I need a A - Q Conversion Support Tool https://www.mitsubishielectric.com/fa/products/cnt/plca/pmerit/renewal/case/support_tool.html However I cannot find the software on any of the DVD's that I have and I cannot seem to find a download. So I am stuck now. Can anyone help point me in the right directon? Any Help greatly appreceiated. Thanks in advance.    
  21. 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?
  22. Original FX3U project written with GX Developer FX Version 8.45X. I now want to program an FX5U with the same program (well, slightly modified). I have MELSOFT GX Works3. How do I import / convert the original project? I have done a web search but can't find the answer. The installed help files don't seem to cover the topic either. Many thanks.
  23. Hello! I have a problem with Allen-Bradley High Speed Counter card 1734-VHSC24/C. I need to make changes to the configuration parameter .OnValue1 (DINT) during the system is running. Now, for changing the parameter value, I need to switch off the module and this can not be done during the line is running. I think that maybe this can be done using the explicit messaging. I could not find information for this from internet, so now I ask you to help me with this item. If anyone have experience or knowledge of this, please help me. I do no have experience using explicit messaging. My configuration: Studio 5000 Logix Designer V24.00, 1756-L71S V24.11, Ethernet/IP, 1734AENTR, 1734-VHSC24/C countermodule.
  24. Hello, I have been so many days trying to comunicate the multiway software trought a serial usb converter with the SCU31 device, using a omron function block to read a holding register, but I can't achieved it. Now Im receiving some frames on multiway, but there is always some errors. I was wondering if somebody in here that have worked previously with modbus and omron can be able to help me in how to configure everything corectly to be able to read the value from multiway, on the plc, and where is this value saved.  I'll upload some captures to show what I have done till now.
