  1. I'm trying to set up an Ethernet/IP communication with a CIP block between a Micro850 and a SMC EX600-sen3 pneumatic Module. I can read the inputs of the module with the configuration below, but I CANT write to SET or RESET the digital outputs. There are NO errors showing communications issues in the CIP Generic Block I am using... I read that for some reason, it seems that there are problems with writing thru Ethernet/IP protocol between Micro family and other devices not from Rockwell... Does anyone know if there is a way to make it work? Configuration that is working to READ: CIP Service Code:     14 CIP Class ID:         4 CIP Instance ID:     100 CIP Attribute:         3 CIP Member ID:         0 Configuration that is NOT working to WRITE: CIP Service Code:     16 CIP Class ID:         4 CIP Instance ID:     150 CIP Attribute:         3 CIP Member ID:         0

  6. hello, Somebody have suggest how need read data from slave using modbus RTU. I am using M241 PLC and read_var function. The picture you can see my PLC program. The data of slave is placed 3394 address. Then I try to read, always "READ_VAR" function get "CommError" which number is 254 that means "The detected operation error contains protocol- specific code"  and "OpenError" which number is 3 that means I don't know. How need read from slave data, which modbuss adress is 3394?

  7. GOT1000 HMI with Q03UDE PLC issue

    python01 posted a topic in Mitsubishi

    I have a bit of an issue with communication between GOT1000 HMI (I think the exact model is GOT1675V) and Q03UDE PLC over Ethernet. The GOT is set to 192.168.1.4 and PLC is set to 192.168.1.2 but I get the error "Communication Error. Refer to System Alarm in Utility Menu". Now how do I access the utility menu? I have tried to tap and hold on the upper corners of the HMI but nothing happens. I also can not switch between screens when I press buttons even though they are directly linked via screen #. Almost like the HMI froze up. Wonder if anyone had similar issue and what the solution might be. Thanks for your help.
  8. Here is a post that we recently completed on the Automation Direct USB to RS485 Adapter.  The USB-485M is a 2-wire USB to RS-485 serial communication adapter for RS485 use. It does not require an external power supply or complicated configuration. It has a Type A (plug) USB connector for the computer side and a universal female RJ45/RJ12 modular connector. This will accept RJ12 and RJ45 plugs.  The USB-485M supports multiple baud rates and is USB V2.0 Compliant. Read the rest of the post...

  9. MX2 Modbus doubt

    Robror posted a topic in Omron

    Hi there! I'm programming a CP1L-E CPU to control 3 3G3MX2 inverters via Modbus. It got some things right, like the INV002_Refresh_X31 block and its parameters. The thing is, I also want to read some parameters from the inverter using the INV206_ReadParameter block. My doubt is, do I need to be careful so both blocks don't execute at the same time and use the serial port at the same time? Is it better to use one INV206_ReadParameter block for each parameter I want to read? Thanks in advance!
  10. 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.  

  11. GOT2000 as MODBUS TCP slave

    Szabo Zoltan posted a topic in Mitsubishi

    I have this setup: FX3G CPU connected to GT2103 through RS422 (CH1). GT2103's ethernet port connected to LAN and set up as modbus TCP slave (CH2). I want to read/write PLC word devices using a modbus TCP client, from a PC. The HMI is acting as a gateway between PLC and PC. I used the Device Data Transfer function to send PLC's D register values to GT's internal GD registers. D0....D9 ==>  GD0....GD9 After some tries, I get valid response from the modbus slave. Reading the holding registers 0....9 (40001....40009), I get only zero values. Those registers can be written back with different values, correctly. I'm sure I didn't understand correctly the modbus address mapping to GT's internal memory. Can anybody help me? Thank you.
  12. Hello everyone    I am working on modbus TCP protocols to communicate between SEW drive and Omron PLC CP1L-EM. I am following modbus TCP function block from Omron, But i have updated that block because of is not fit to SEW modbus communication. Currently, I am sending a control work to SEW but I am getting error on Modbus TCP from SEW drive, which is invalid data. So I am looking your help is you work with SEW drive before and communicate over modbus, then please let me know how to make a data string for read and write (SEW Drive function 23). I am using 3PD data structure.    Thank you
  13. 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.
  14. Hello friends, I am an Omron PLC user, but have never used modbus before. I have to connect an Omron CP1L-m to Beckhoff bk7300 via modbus serial gateway. 2-wire RS-485 connection (CP1W-CIF11). I have seen an easy to use Modbus RTU master for CP1L CP1H CJ1 CJ2 CS1 but the examples are not for dual port CP1L-m. If I change the PLC model "CP1HCP1LModbusDualPort" to "CP1L-M", the compiler tells me a lot of warnings about variable types. Is Modbus RTU Master easy to use for CP1L CP1H CJ1 CJ2 CS1 compatible with CP1L-M dual port (port 2)? I have tried to use it but it didn't work, error 02, illegal function code. Somebody could help me? Thank you Enric

  18. 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
  19. Hey all,  So I am looking for some assistance because I am not understanding how the tags on an HMI and within a PLC are linked. There are no 'physical' buttons, just what is on the HMI. It is controlling a chiller. Communicates over Modbus TCP/IP. The PLC is an IDEC. I have some-what worked out how other tags are working when they are words being passed back and forth, but this one has me stumped. I've attached a few screenshots for referral. It looks like the run and unload buttons for the chiller are a single bit/BOOL toggle (but the chiller running latches itself in the PLC when the chiller starts to run). The stop buttons appears to be a parent for the single bit/BOOLs and when it is pressed it resets them all both on the HMI side and within the PLC side.  
  20. Hi there, I have a controller NX1P2-1140DT. I want to control a VFD with modbus serial communication. Can someone help me start from scratch ?

  21. CX-8190-Modbus Srv

    johnnieblank posted a topic in Other PLCs

    Hey guys, I am trying to communicate between a Beckhoff CX-8190 & a third party fieldbus module that supports Modbus TCP, now I am able to write/read to the fieldbus when twincat is running on the local machine (laptop), but when ever I connect to the device and run the same function block it doesn't write nor read to the fieldbus. I am assuming that the modbus server has something to do with it, so is there a way I can install it to the plc ?

  22. KINCO PLC as MODBUS RTU slave

    Francisco1998 posted a topic in Other PLCs

    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!
  23. 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  
  24. 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.

  25. Serial communication with KINCO PLC

    Francisco1998 posted a topic in Other PLCs

    Hello to everyone. Nice to meet you all. I am programming a KINCO PLC model HP043-20DT using ladder on KINCO BUILDER. I need to establish a serial communication with my PC. The PLC has a RS485 port which I adapted it to USB to connect with my PC. The PLC allows, at least, two ways to establish serial communication: MODBUS or free-protocol. I've read the software manual and tried to reproduce the examples it provides using the instruction blocks for MODBUS (MBUSR and MBUSW) and free-protocol (XMT and RCV) communications. However, I could not receive the data on the PLC. I could effectively transmit data with XMT from the PLC to the PC and I could verify through a tool called Access Port. In relation to MODBUS, I am using a simulation tool called Multiway from OMRON, however, I get no response from the PLC. If any of you have some experience with this software or this device, I would like to ask you how could I solve the problem. Thank you for your attention. Kind regards.
