  1. Hi, I have a problem with Omron PLC and Beckhoff IO. The IO just disconnects in a few minutes and comes back! I received different errors: Link off error, Illegal slave disconnection, process data reception timeout. When I also check "Display Diagnosis/Statistics information" I see errors on all ports A and B of all nodes.  I have called and talked to both Beckhoff and Omron.  I have two NX1 and one NJ101 to test. And I have three EP2318-0001. I have the same problem with all the PLCs and EP boxes. It does not matter if I have one, two, or three nodes. I have tried different revisions of the EP2xxx from the XML file, different settings for the slave, different task periods, and the error still is persisting.
  2. Hi! I would like to ask your help. I want to know more about the communcation systems what allen bradley use. Most important for me, is Ethernet IP communication, Controlnet communication, Sercos (servo) communication, maybe devicenet communication.  I know I can find some manulas on the web, but I thought I ask it here too, maybe you guys have some more documents which is contain more information. Every information is highly appreciated. Thank you very much guys.  
  3. Hi I am looking for a way to read and write data from PLC omron words, bits via FINS or EtherNet/IP protocol using python programming lang. Does anyone have any results in this? I really want to see your work, because all my attempts have failed. Thanks.
  4. I am new to automation systems and devices and I just want to know how to connect two HMI's (each one would control different things) to one PLC using Sysmac Studio and NB-Designer via Ethernet. The model of the PLC is NX1029020 and the HMI's are one NB10W-TW01B and an NB7W-TW01B. I searched for info about this topic online but I couldn't find anything that worked for me, I saw an article from OMRON where they connect two NB's to the CP series, but in my case, NB designer doesn't allow me to insert more than one HMI in the same project, I also found something similar on a youtube video that gave me an idea about how to connect multiple HMIs exporting the pks file and importing it to another HMI project but I still can´t figure out how to add both to my PLC. I would thank you a lot if you could help me with this because I know it's not a rare implementation, just I haven´t found the right way to do it. I also leave the links to the Omron article and the youtube video I found. https://www.myomron.com/index.php?action=kb&article=1554 https://www.youtube.com/watch?v=rXx5lut7G9I
  5. KINCO PLC as MODBUS RTU slave

    Hello to everyone. I hope you are doing well. I'm trying to establish a communication between my PC and my KINCO PLC. The manual states it supports MODBUS RTU protocol, so I downloaded two different Modbus Master simulator I found out: Multiway from OMRON and qModMaster. None of them seem to work properly. I attached some pictures of the messages I get. https://ibb.co/f1mCSNt Multiway message https://ibb.co/bP5cX1t qModMaster message I include the configuration of the communication parameters. https://ibb.co/nMty8D9 PLC parameters https://ibb.co/6RTqVfC Multiway parameters https://ibb.co/N1XTccd qModMaster parameters According to the manual, in order to play the role of Modbus master with the PLC it's necessary to configure some instruction blocks (I'm programming in ladder). However, I could not find any block to configure as Modbus slave. I don't know what else I can do. I'm in trouble with this task. Am I making some mistake? Thanks for your attention.  Kind regards!
  6. Hey all, I am having some issues with a Keyence IV2 camera which has Ethernet/IP functionality.  To summarize briefly, it has been configured and reading the data into my PLC (NJ501) into a structure data type.  The issue I'm having is that I cannot control this on a bit level for triggering the camera, etc.  I was reading that a Union type is the way to go, but unfortunately, I stopped getting data into the PLC when setting it up that way.  According to the configuration guide for Rockwell and setting it up in the Network Configurator, I needed to go with the SINT type.  When registering the device, the 8-bit option was necessary since the Input/Output sizes needed to match.  This was predetermined by the EDS file for the IV2. I am stumped as to how to get the data to read into the Union Type, and any suggestions would be greatly appreciated. Thanks, -K  
  7. Hello, I have to make communication using Ethernet between omron CP1H and siemens s7-1500 plc. I was thinking about Modbus TCP or Ethernet IP using theese adapters: Modbus TCP - CP1W-MODTCP61 Ethernet IP: CP1W-EIP61 But I am quite new in Omron, and I am looking for some exapmple codes, FB. Do you anyone have experience with that?   Thanks for all responses.
  8. Good day everyone, First post here so hopefully I'm not violating community guidelines in anyway. I've got a system that has some 50 odd Micrologix 1100 and 1400 in use and I'm currently working on setting up an auto timesync for all of them using just 1 of the PLCs that will be my master time PLC. So far I've put together the logic for all the message instructions with the corresponding IP of the slave devices. I'm running. Into an issue with not being able to terminate/break the message connection on a PLC that I have already synced. Is this even possible to do on the ML1100. Once I get to 16-17 messages DN it starts to ER and will not complete any further messages. What I have is a message instruction ladder with a timed trigger to activate a MSG and write the RTC data then time down and connect and write to the next and so on. When it triggers the message instruction of one PLC it also fires an OTE to trigger the BK of the previous message instruction. However it doesn't seem to be actually cutting the message connection and holds it persistent until a power cycle/download event.
  9. I want to establish Ethernet IP communication between the following PLC CPUs. Schneider Electric - BMEP582040 Honeywell - ControlEdge UOC CPU900-CP1. Where the Schneider must be master and Honeywell must ne adapter. Let me know if anyone have done this or can help me to do so.
  10. QCPU to 2x kyence iv2

    Hello all, we are using Q03UDECPU and via built-in ethernet port its connected to two IV2-G30. (through unmanaged switch) to establish connection we are using FB LQnUDEEthActive (hereinafter referred to as  FBLQ) two instances of FBLQ in two instaces of our FB which is responsible for creating messages that are then send via FBLQ Both keyence devices have different IPs, ports and connection number. Problem is that it is working flawlessly, except the time its not working :/ from time to time it simply doesnt trigger Keyence device. It looks so far like its independt of turning machine OFF/ON, also both keyence devices are used in different times (about 10-20seconds of difference) Im currently working on sime kind of internal diagnosis to see whats happening when its not working, but im just curious if there is something obvious we are missing? any help will be apreciated Thanks

  12. hello Every one,    I am using a CP1-L PLC and want to communicate to domino ax350i printer over TCP/IP socket programming. For socket programming, I used Omron Function Block CPU012_SendCommand.  I defined network ID and node address. However, I am getting 0502 error which means routing table is not set yes. So, how can I set routing table for both devices?. my PLC on 192.168.250.1 and Printer is on 192.168.250.123 node 7000.    Can any one suggest me best way to do.  Thank you   attached file is for what I did in setting and program for the communication.      
  13. Monitouch HMI slow screen

    Hi there! I'm having some issues with a FUJI MONITOUCH V9100iSD HMI that communicates with a CJ2 PLC via Ethernet. This HMI is a migration from a previous V810iSD model. The thing is that the previous model worked correctly, but when using the new one, the HMI seems to be pretty slow when switching screens, for example. All parameters are the same, and after reading Fuji's FAQ, I've run out of ideas. Have you faced the same problem? Thanks in advance!
  14. FX3U to FX3U via wifi

    Good day fellow PLC ninjas! I have a question/ concern which I would love your opinions on. We have 3 FX3U PLC’s+ENET cards. Two of the 3 PLC’s move around in an EMS trolley. The other is a ‘base station’ with a GOT2000 connected via Ethernet. Base PLC IP = 192.168.1.11 HMI IP = 192.168.1.31 Carrier 1 IP = 192.168.1.61 Carrier 2 IP = 192.168.1.62 I have programmed the base PLC to use Active communication; we are using fixed buffer communication to send and receive data to/ from the Carriers. The carriers are set up as Fullpassive ‘slaves’. This part works well and the update time changes (using a counter in the base station) from 1s to 100ms (because it enters a different work station).  My issue is the following: using a network sniffer (WireShark), I pick up plenty of re-transmits and sequence number errors coming from the base PLC’s ENET card. This is troublesome and causes delays when the update time is required to be fast (100ms). I am sending and receiving 10 words of data. The wifi seems stable, and there is minimal noise in the area. The power has been turned down and the antennas used are suited well for the application. The antennas are at a similar height to minimize possible loss of signal. I have LOS (line-of-sight) to the carriers at all times; to at least one of the antennas (I am using 802.11n). Has anyone picked up issues or found settings which can be used for comms over wifi? I can easily do this using a S7-1200 Siemens PLC and have done so using 12x S7-1200 clients and 2 AP’s with 1 base PLC. I have also successfully done this using 8xFX3U client with a System Q base PLC. My suspicion is that the delay in reading and writing to/ from the BFM in the ENET card is causing this. I am not sure that if I change to a FX5U will help. The communication cards on the Mitsubishi PLC’s seem very limited. Does anyone have any technical details on the access times between the CPU and communications cards’ BFM? Help is as always, appreciated.
  15. CP1L Unknown IP

    Hello. I have CP1L EM30 with unknown IP. I have tried to use "Direct Ethernet Connection" with "Network Browser" but with no success. I have manually set the ethernet IP4 address to 192.168.20.20 / 255.255.255.0 I've got error: "The OMRON Ethernet Direct Connection Manager service is starting in Safe Mode because Windows APIPA is enabled. (0x82020003)Omron.Cxmw.Modules.SystemLibrary.SysLibException" The PLC does NOT have default ip 192.168.250.1. What Can I do? Please help. Thanks. BR, Andrej.  
  16. Hi all, First i apologise for my english, but it's not my main language. I am very new at this world so sorry if my question is too newbie but i have been for several hours trying to get some data from an Omrom NPX1P2 DT-100 using Ethernet/IP and now i am a bit desperate. I am trying to connect this PLC using a C# Library provided by steffan rossman and it seems to be very easy,  i can manage to connect it but every try i do to request data it fails. As i can see there are several ways to get the data, for example: In this example the function GetAttributeSinglec(ClassID, instanceID, attributeID) i need the ClassID, wich i don't know what is, the instanceID, i think in my case is 100, and the attributeID wich i don't know what is or where to define. If someone could help me about how to request data it will be very appreciated. Thx in advance    
  17. My HP laptop will lose communication with Mitsubishi PLC occasionally after removing ethernet cable to download from WiFi. Our company limits the ability to use the wi-fi when I have an ethernet cord connected to my laptop, it has to do with security. If I am connected to the Mitsubishi PLC, then want to download another file from our autosave, which we connect through the wifi, I have to remove the ethernet cord from my HP laptop to enable the ability to go wireless, however sometimes when I attempt to go online with the PLC after I re-connect my ethernet cable, GX developer will not allow it. I can ping the plc and even go online with other PLCs on the network, but for some reason, the one I was connected to will not connect. I restart my computer and even re-download the file again from autosave but no joy. Its not until an unknown amount of time that it will allow me to re- connect, its as if I lose the socket connection on the plc and it needs time to reopen. I talked to our IT department and they have no ideas. Thank you in advance for any help on this matter.
  18. Digital sealing

    Hi, I'm trying to figure out a way to make an automatic digital sealing for a NX-controller. Functionality: Each time I do a remote connect and/or change to the program on the PLC via VPN/Tosibox I want a counter to automatically increment. This counter is the digital sealing (checked by the authorities from time to time), and is displayed on a HMI. When the sealing breaks, the new value of the counter has to be reported. I've been thinking about incrementing the counter each time the Ethernet port on the PLC registers a rising edge on online establishment. But this will not work if there is a power failure (then the counter will increment unitented), or someone by mistake unplugs and replug the Ethernet cable. Antoher idea was to ping a specified IP-address, but there seems to be no PING-functionality. I've also been thinking about using some program data (i.e. last modified), but it seems there's no system variables on the PLC that contains this kind of information. Any ideas how to solve this in the PLC? Basically I want to know if the PLC program has been changed or if there a specified IP-address has been connected to the PLC-network.
  19. How to scan Ethernet/IP network?

    Scenario: You show up on site and the only knowns are Omron PLC and EtherNet/IP network. You have a laptop loaded with CX-One, an ethernet cable, and the ethernet port that is connected to a known EtherNet/IP Omron network (you can not see the PLC). I have previously worked with Siemens systems and used Primary Setup Tool and Proneta with wonderful results. Do similar tools exist for an Omron environment?  Question: How to (relatively quickly) scan an EtherNet/IP network for connected devices without knowing their ip addresses?  
  20. Hello guys, I have an application with a Delta PLC (slave), Load cell module and Delta HMI.  The problem is that the Delta PLC has to report to the already existing platform of Siemens S7 PLC (Master) with Profibus. The Master (Siemens) writes and reads data from the Delta PLC. The question is, how can I set up the Profibus communication? Are there any documentations about the Memory Mapping, configuration etc. There are some modules for Profibus Slave from Delta but I cannot find any references or anything. Thanks in advance.
  21. Have been able to exchange data types of BOOL, INT,  DINT & REAL between Omron NJ/NX CPU with Allen Bradley Logix CPU's with Ethernet/IP using the CIPUCMMRead & CIPUCMMWrite instructions. I now have a need to exchange "STRING" variable types. Have tried varions string lengths in the NJ without sucsess. AB default string length is 82 & Omron 256 but I think the difference is the length headder that AB has with within their String Tag type. I know I could convert my strings to an array of bytes & sent them this way, but was looking for a solution to sent them as native strings. Hope someone out there has done this & can share their leg work? 
  22. Hi all,   Is it possible to simulate LMC058 PLC with ethernet in soMachine software. I want to test the logic written in PLC which uses tcpudp library.
  23. I have a 2 CompactLogix PLCs running right now, communicating CIP Safety and Standard data over Ethernet I/P.  For reasons I can't explain right now, the IP address of the second one HAS TO change semi-randomly (the 1st PLC is static).  Setting the 2nd PLC's IP to static or assigning it a static DHCP address is the obvious solution, but for the purpose of this question, that cannot be done. Is there a way to programmatically change its IP address on the 1st PLC's program?  (There is an HMI attached to the 1st PLC and adding a screen to enter in the new address would be trivial.)  The only bit I'm still missing is how do I change the IP address on the module in the 1st PLC so that it's pointed at the right IP address of the 2nd one when it changes.    I found instructions on how to use msg instructions, but that hasn't worked yet.  Any help would be appreciated. Thanks!
  24. I have an Ethernet/IP bus and system including Ethernet/IP devices with CPU 1756-L81ES ControlLogix. PLC is connected to the switch. Bus is built from the switch as a line. Can I connect the last device on the bus back to switch again? In thes case bus will be ring. Do I get problems with connection it this way. Switch is Stratix 2500, which is lightly managed switch. I believe it will increase the traffic in the bus.
