  1. FINS Communication with C++

    Hi, I'm having a little trouble connecting to a PLC from my program. I thought my previous post a few months ago fixed it, but apparently it did not do much. Here is my code: And here is the resulting reply from the PLC after converting it to hexadecimal So far, I've narrowed it down to the issue that my program is sending 64 instead of the 18 that was specified by the FINS command. I assume that the received error is due to the fact that the PLC did not receive the correct instructions from my program. The "End" is not sent by the PLC, it is a personal note for me to know where the received message ends. My goal is to simply receive signals from D00 to D68. I imagine that the received string should be in the form of: 00 C0 00 02 01 01 00 01 00 00 01 01 [Response Code] [Data] Can someone help point out where I can start looking for why my program is sending 64 instead of 18? I do think I am messing up something simple here, but I'm not sure where to start. EDIT: To clarify the models, I am connecting over Ethernet to an Omron CP1L-M40EDT with CP1W-CIF41 Thank you in advance!

    Hi all i've been trying to make a simple timer in structured text which is turned on and off by a single input, all instances of flip flops i have found seem to be 2 input. any help or examples would be appreciated example of programs; Pulse signal received, start timer Pulse signal received stop timer
  3. Pressure transmitter drift

    Hello all this isnt strictly omron/programmer but has anyone used much in the way of pressure transmitters? we have a wika s-11 pressure transmitter on one of our machines installed roughly 7 months ago where the scaling does not seem to be linear, i only started working here around that time so i dont know how it was installed etc. but its a 0-40 bar 4-20mA transmitter connected to an ad081 4000 resolution connected to a cj2m. so the conversion should be nice and easy 100 raw data = 1 bar however it seems to be scaling logarithmicly to me as we checked with a 2 different guages and when they were at 2 bar the transmitter was showing 137 raw data and at 8 bar it was showing 737 raw data and this seems to keep scaling in this fashion as we get to higher bar. is this a common fault on transmitters? is there anything else that could be causing this? how often would you normally expect a transmitter to last? i checked my scaling FB on another transmitter connected to a compressor and it worked correctly so its not the maths used   thanks in advance
  4. Hey, I have a project which one part involves using a RTD PT100 (0-100 Deg.C 4-20mA) connected to a CJ1W AD041 (ATD input card), the PLC is a CJ2M Basically the PLC needs to read the RTD and display the temperature on a Omron HMI (NS10), via Ethernet, Could someone please help me out with a basic example program - to read and convert the RTD - ATD value to store in memory. Your help would be most appreciated. Thanks  Richard       
  5. CP1L connection issues

    I am unable to connect via ethernet to CP1Ls version 1.0 with CX programmer version V9.61 but I am able to connect with V9.60. Is there a work around that will make me able to connect with the newer software?
  6. Dear all, Does anyone have a NTXS verion 1.03? I can only find ver 1.04 in the internet. I am having a trouble while replacing NT3S-ST124B-E. The old one is using RS422 Communication. using a 5 cable in pin 1, 4,5,8, and 9. But it can not communicate after i download the old program I uploaded(firmware ver 1.03) to the new unit (firmware ver 1.04). it keep saying com 1 Communication Error.  From the manual NTXS software, I discovered that the communication driver supposed to be downloaded together with the firmware.   I used this cable RS-232 connection for programming (upload /download) and it works perfectly fine: db 9 Male (NT3S-ST124B-E) to db 9 female (PC) 2 to 2 3 to 3 5,9 jumper to 5   The program i managed to upload using NTXS 1.04 in Win 7 32 bit and sucessfully download to the new NT3S in Win XP 32 bit (tried so many times but it fails on Win 7 32 bit). The program says that the NT3S is connected to CJ1 PLC. The cable used to connect to the old NT3S is using Pin 1,4,5,8,9 which means it should be RS422 (Xtra Drive). I wanted to try using version 1.03 but I can not find it.   Regards, Budianto Scanner NT3S.pzm
  7. Good day everyone, before I start asking my question, just want to let you all know that my knowledge with PLC is not that good. I'm still learning on how to do it. So currently I'm working on a project that trying to obtain data from Omron PLC. I was told that I can't touch the Omron PLC program or modify it. That Omron PLC is connected in an isolated network within a router. Other than adding Network Card on the device, can I use another PLC (any brands) to get the data from that Omron PLC through the router? The communication protocol using here is Ethernet. Can i just tapped into the network and take the data with that way? Or the other method I'm thinking is that, the Omron PLC will feed the data to a server, can I just obtain that data from server by using OPCUA? I heard there's some PLC that have the OPCUA function, I just make my PLC into the cilent and request the data of that Omron PLC from server through Ethernet. Is this possible? Please let me know whether my method works or not, thanks in advance guys!
  8. CJ1W-EIP21 to ControlLogix

    Hello, Just made this account to get an answer hopefully quickly. I have an existing Omron CJ1M that is talking to a ControlLogix over a CJ1W-EIP21. I don't have experience in configuring Omron PLC's, but the Omron and Allen Bradley are already messaging to each other. My question is how can I get more words to be transferred between the two plc's? There are already 4 words (INTS) being transferred and are working properly but I have used up all the bits and am now needing at least 2 more words. I know in RSLogix 5000 I need to make the array size bigger, but where/how do I do that in CX-Designer? Thank you for any help.
  9. IOT Omron

    hi everyone, im new here. I have a question, how to connect PLC Omron to Node-red (for IIoT)? if PLC Siemens, it has Siemens IOT2020 to connect PLC Siemens to Node-red. Do Omron haveit own iot gateway like Siemens?
  10. CP1E USB protocol

    Hi, this is my first post in Mr.PLC :) In CP1E-N20 I can send c-mode commands to RS232c port to access the memory. The access memory through the USB port is possible? And What is the protocol?    I find a project in https://program-plc.blogspot.com/2015/12/omron-plc-usb-protocol-used-for.html to CP1L-L10 When I send to CP1E the "PLC_Run_Mode" = [AB,0,11,80,0,2,0,0,0,0,0,0,69,4,1,FF,FF,4,3,AE], I should get  [AB,0,10,C0,0,2,0,0,FB,0,0,0,4,1,0,0] but I receive [AB,0,10,C0,0,2,0,0,0,0,0,0,69,4,1,0,0,1,EB]   I need to understand this protocol/message, but I not find information. The Omron W342 does not refer to these messages starts with "0xAB, ..."   Someone can help me? Thank you. Jorge
  11. Greetings everyone. I'm new here. Hoping to get help to operate the Omron V400-R2 barcode to the Mitsubishi QJ71C24N so that they can communicate the two devices with the correct method. PLC: Mitsubishi: Q03UDVCPU; barcode: Omron V400-R2; serial communication module: QJ71C24N. I use RS 232 communication cable, I have tried using predefined protocol and non protocol procedures but still can't communicate the two devices. I really appreciate your help.
  12. FTP from OMRON NX1P PLC to a Delta HMI

    Hi all, I'm looking to try and send data from the SD Card on my OMRON PLC to a flash drive on my Delta HMI - DOP107WV using FTP. So essentially I need to use the HMI as a FTP host. Is this possible? And if not, is there another way of doing this?  Thanks, Ibrahim

  14. Hi there, Im having issues controlling ATV 320 VSDs over Modbus RTU with a M221 plc, does anyone have any pointers for me to look at? I believe I Have set everything up correctly but when I run the program on the plc the atv's just stay in 'NST' state I have included screenshots if they are any use   My speed reference in this example is taken from the memory word %MW0 which I am inputting via a HMI   I have addressed all my ATVs accordingly in there setting with the correct Modbus parameters and selected Modbus under the FR1 configuration, am I missing anything?? Any help is appreciated as I am really struggling   Tom
  15. Hi guys, I just starting to use Sysmac Studio. Its a bit confusing as I am currently used to CJ series PLC. Usually, we can use P_1sec, P_0_2s and so on to create a simple clock pulse timer function. However, I couldn't find the command or FB to do that in Sysmac Studio. Anybody could explain on how to do that in Sysmac? Thanks 
  16. OPC Client with CJ Series

    Hi everyone! I have an OPC UA Server running on a PC that I need my CJ2 to communicate with. I'm having a lot of trouble to find how I setup this PLC to work as a OPC UA Client. Does anyone have any idea of how to do it? Thanks in advanced! Best regards, Alex
  17. Hello to everyone! Our company is trying to make a quick disconnect for motors that connect tp servo amplifier R88ND-1S. As I know Omron doesn't have any options to do it or make an extension cable. Does anyone tried to cut the cable and make custom connector? If yes, could you share your experience? I'm afraid of having issue with encoder count. Thank you in advance! Scotty.

  20. Hello everyone. I need help setting up a data transfer between a CP1H with a CIF41 module, and a CJ2H. I realize this can't be done with Ethernet/IP, so I figure FINS should do the trick. I've read up a bit on the SEND and RECV instructions, and tried to set up a RECV in the CJ2H (since I know the CIF41 can't act as the sender, it can only receive), but I just can't seem to get it to work... I work at a factory and we're setting up a data collection system. It is mostly CJ2s with EIP tags doing most of the transters, but there are a few machines where EIP tags can't be utilised. Unfortunately I don't really have the freedom of choice what to work with, my budget is already pretty dry, so I kinda have to work with what I have... We need to read 100 WORDs from the CP1H to the CJ2H and send 10 WORDs from the CJ2H to the CP1H, so I figure I'll need to make both SEND and RECV in the CJ2H. CJ2H-CPU64EIP Has two EIP units, built-in and an EIP21. Acts as a relay device to the internal production line network. All the machines on the line network send data via EIP tags to this relay machine. The internal network: Built-in EIP (CPU Unit 0) IP: 10.1.95.80/24 FINS Net 95 FINS Node 80 External network: CJ1W-EIP21 (Unit 2) FINS Node 9 FINS Net 2 IP 10.1.99.9/16 CP1H-X CP1W-CIF41 in the left slot. IP: 10.1.95.180/24 FINS Net 95 FINS Node 180 They are on the same subnet within the line network and the same FINS Network as well. I have successfully set up routing tables and can connect from the external network via the added EIP21 card on the CJ2H to the CP1H PLC and work on it in CX-Programmer and other tools. That should mean the communication works, and I'm just failing to configure the RECV parameter properly... Here's what I have right now: I've pretty much followed the example in the W465 manual from page 235 in combination with the Instruction Help for RECV. (Instructions horizontally are intentional for the purpose of saving vertical space for this screenshot, I normally have them vertically. Also sorry for basically no symbol comments...) In the CP1H in D0 I've input FFFF. I run this by setting on W511.15 and hope that FFFF will appear in E3_3800, but no such luck. A202.00 does blink indicating the logical port did get used and the instruction executed, but didn't work as needed. I'm not sure about the response code. Here's how I understand the control words: D7700 being #0064 means 100 WORDs transmitted. D7701 being #005F means that the FINS Network of the PLC I read from (CP1H) is 95 D7702 being #B4E4 means that the FINS Node of the PLC I read from (CP1H) is 180, and the Unit address on that PLC is the Serial Communications Board Port 1 (I think this thing is what I'm getting wrong, I just can't figure out what to put here... I've tried 00 for the Unit address and that transferred from D0 on the CJ2H which isn't what I wanted, I've also tried #10 to specify a CPU Bus Unit 0, as well as FE to specify "Unit connected to network (not necessary to specify Unit)", but none of these worked) D7703 being #000F means no response needed, use logical port 0, and retry 15 times D7704 being #0 means default timeout Can someone please tell me what I'm doing wrong?
  21. hello expert i want ask some help So i tried to communicate my Omron PLC (cj2m cpu31) with SCADA from Schneider (power logic) on my omron side the comunnication on PLC already take to communication to NB so i add communication module CJ1W-SCU41-v1 I want asking how to open the communication if i want the scada become a master and my plc become slave i got this from omron website is that program compete for my case? i need configuration for scu41 module also to communicate or if you have suggestion i really open i just need to open port RS232c from scu41 so scada can read the data from my plc  tahnkyou for your help MRTU_CPU_Slave.zip
  22. Ok so I recently got the Factory i/o software to practice plc programming more in depth.  I got it working easily enough with the siemens TIA software and I am now trying to get it to work with the Omron Sysmac Studio software.  I am not sure if it is possible or not.  I have access to the hardware but I was really hoping to use the simulation like I can in TIA.  Any insight would be appreciated on the subject.
