I'm tired of using 4-20 connection of load cell monitor to analog input. I'm thinking to switch to RS 485 or Rs 232 or Eternet but i have no idea how to configure the plc to connect to Load cell monitor.
Then what command i can use to the programmer to be able to use it.' ( 4-20 connection is not accurate because sometimes data may not be the same to the load cell out.) I use the analogue converter see the attached image. I get that here in mRPLC Forum.
Guys help me please.
Thank you.
hello, i want to connect CP1E to EK300i (weighing scale) with RS232 communication.
i attach file of datasheet ek300i, wiring CP1E to ek300i and my cx programmer. if i push send data on ek300i, com LED indicator in CP1E is on.
and i dont know why my cx programmer can't change data of memory with data from ek300i?
what should i do?

Hi all,
I’m having some problems regarding a digital input from a remote ethernet coupler input.
My setup contais an Omron CJ2M cpu33, a switch, an Omron NS5 HMI (also ethernet) and 10 Wago Ethernet/IP couplers, all of which have 2 digital in- and 2 digital output cards.
Every machine cycle all couplers recieve an input from a regulair proximity switch, this signal is high for about half a second and switches at a frequency of about every 2 seconds.
Despite the fact there’s no high speed stuff going on here, the pulses are not processed properly. Monitoring my program I can see that the inputs are skipped and somtimes are not processed even for several machine cycles.
Is my network too slow, can it be a scan time issue, or something else.
I’ve come a long way building this system but I’m still fairly new to plc programming.
Hope someone has a suggestion.
Best regards,
Andy
I apologize in advance if I am unclear as to what I'm trying to do. I've retyped this several times and it seems to be one of those things that's hard to communicate if you're not there to see it - Like Christopher Walken trying to explain Baseball in Blast From The Past.
I'm writing programs for an NB10 and a CJ2M-CPU32 with Ethernet comms between them. I am waiting on delivery of the CJ2M-CPU32 which is taking forever, and in the mean time I've been using a CJ2M-CPU12 that I have laying around - it doesn't have an Ethernet port.
I've already programmed a significant portion of both HMI and PLC, without the benefit of having them communcating with each other. Now I'm getting to the point I really need them talking and getting desperate without my CPU32, and trying to make something else work.
The only Omron PLC with an Ethernet port that I currently have is a CP1H with a CP1W-CIF41 option board. All addressing in the HMI I have mapped to points in the (future) CJ2M-CPU32. I tried using my CP1H as a "simulated" CJ2M with the same IP address, but the HMI is having none of that. It's giving me a "[1] PLC Response Error," which is different than the "[2] PLC No Response: 00-0C-3" that I get when the cable is unlugged or when the PLC IP address is wrong, which tells me that it is "seeing" the PLC at the correct IP address but it too smart to be fooled by a CP1H when its looking for a CJ2M. When I put a dummy program (NB/CP1H) in the NB and in the CP1H, it works; I can toggle a bit from the HMI in the PLC. But when it's looking for a CJ2M, apparently only a CJ2M will do.
In the NB program that I've already invested so much time in, I can't simply change the model of PLC. If you start with CJ series, that's it. If you want to change models, you have to delete the CJ series, and put in a new CP series. But when you delete the CP series, it deletes all of the addressing for every single widget on every screen, that was mapped to the original CJ series.
I hope I have clearly stated my problem. Are there any suggestions for either tricking the HMI into thinking a CP1H is a CJ2M, or migrating the NB project to a CP1H without losing all addressing, or something else?
Thanks in advance,
Strantor.
I just received a box of Omron parts from my supplier and they had dust/lint on them. That caught my eye so I looked harder and realized there are no stickers over the vents that I'm used to seeing. The ones to keep debris out during installation and say "remove after installation."
These were purchased as NEW parts and they were inside their proper boxes sealed with Omron tamper tape intact. The boxes do not look like they have been opened. The PLC and I/O cards have MFG dates <6mos old.
I am used to Omron components coming with the debris sticker, and had they not been covered in dust I probably wouldn't have missed them. I don't know what to think. Now I doubt my memory of the stickers; I know for a fact I've seen them on Omron PLCs and I/O cards, but on ALL of them? I'm just not sure. And now I can't remember when was the last time i specifically opened CJ1W I/O. So I Google Image searched my specific cards and found several images of them with the stickers. I know that, at some point, these stickers would have been on my cards.
Has Omron ceased the practice of installing these stickers? Or did I buy not-so-cleverly disguised used cards?
Hi,
I'm trying to communicate Omron CP1E unit with PC via serial port using hostlink protocol. I need to read the Timer/Counter SV value and write the timer/counter SV values to the PLC. I'm able to use other C mode commands (like RC (timer/counter PV read), WC (timer/counter PV write) etc.) but when I give the command for Timer/Counter SV Read 1 which is R#, I get the response as IC (Undefined Command). How do I write or read the timer SV Values?
Example command and response :
@00R#TIMH001028* (TIMH is the high speed timer, 0010 is the timer number and 28 is the FCS)
Response:
@00IC4A*
Is is that CP1E doesn't support these commands? If so what is the equivalent command that I should send inorder to perform this?
Please help.
Hi every body,
I'm new in PLC world, please give me advice. I will set up Panasonic minas a6 servo with CJ1W-NC-213, installed on CJ1M-CPU21.
I try to test using cx-position, but no moving at all, i check out pulse train from nc unit, there is no voltage.
I using bilt-in output, using sped and puls instruction, Everityng goes well.
Please give me advice what i'v be missing on setting
Regard
Dear Gentlemen,
I have used CJ1M - CPU 12 - ETN PLC. I m very new at Omron, so my question is: Can I connect from Cx-programer to PLC via integrated ethernet port or the peripheral port is only way(I do not have the communication cable)??
I know that integrated ethernet acting like ETN 21 module, and that my last oct. of IP adress need to be set in node (transferd to hexadecimal).
Do I maybe need to use FINS and Cx integrator and how to setup my computer (cx programer) there???
Thank You very much in advance!!
Hi members of the forum , I have a problem that need to be solve .
Need some support in data transfer from Barcode – PLC – SQL.
Below is the situation.
Currently now in each material we use in machine there will have 3 information of barcode to be capture. How can the PLC detect all 3 information and send it to SQL as one data.
E.g: material cage over mould
Info that ned to be capture:
Product ID No: BM01MFG0001-01-B
Work order No: WO151885
Qty: 300
All three information can be send as BM01MFG0001-01-B,WO151885,300 and how can I send it all to get there to our SQL?
Currently now I'm using NJ series and NJ-DB.
Question : What need to be change to make all above data to be send to SQL column Cage_Batch_No
Below is the current RUNG that we have.
Hi,
I'm new to Omron. Have worked with others like Delta and Unitronics. Just like to find out if the above model can work with a gsm modem to send text message to designated mobile phones. From the forum I see that CJ1M CPU22 could. Can CP1E? If yes, can you give any guidance as to how to go about it?
Thanks.

Hello
I'm quit new in this world and i have several doubts about the comunication of EIP. I'm trying to capture the comunication betwen a CJ2M and an NS8 HMI.
I was trying with MolexEIPtool, so i could understand better the communication process and i did a little. Here is the wireshark capture of an get all attributes request: CIP_Molex_tool.pcapng (The last two packets are another unconnected request).
I can see the request for list services, the register sesion request and the Forward open request. Then, i can see the request for service "get_attributes_all" and how the cj2m responses with all the attributes. Finally, the forward close request.
But when i put my computer betwen the two devices, i cant figure it out what is happening. Here is the capture: CIP_OMRON.pcapng
I can see that the packets are "SendUnitData", so i think it is a connected transmision, but wireshark cant decode the rest of the frame, so i dont know whats going on.
Thanks
I attached lsis HMI with CQM1. communication done all outputs are showing on plc but physical input can't b putted. What's the reason plz help me out
I attached lsis HMI with CQM1. communication done all outputs are showing on HMI but physical input can't b putted. What's the reason plz help me out. I made rs232 Cable as following 2-2,3-3,5-9. Shorted socket pins 4 6, plug pins 4 5. Is it necessary to short socket pins 7 8 and to link FG?
Hello,
I am trying to connect a Weidmüller UR20 Ethernet I/P (Hardware version 1) to a Omron NX1P2 PLC via Sysmac Studio. I have imported the Weidmüller EDS file into Sysmac studio and connected two tags to the target variable 101 and 102 (I also tried using a array of bytes and a single word).
When I transfer this configuration to the controller and set the controller in run i get the following error: Tag Data Link Connection Failed (0x84070000). I have tried to update the firmware of the Weidmüller I/O but this doesn't seem to help. Also the web interface shows no connection with the PLC. 
I also tried to setup the connection with the CX network configurator but this gave the same result.
Is there someone who can help me with this problem
Thanks in advance.
Hello.
I know there were many versions of the C200H series PLC CPUs; and not all the literature is available online.
Can anyone help me to confirm what are the differences between C200HG-CPU43 and C200HG-CPU43E?
Are these two different CPU part numbers or is it just one?
If these are two different CPUs, Can -CPU43E replace -CPU43?
Omron list price only shows -CPU43E as an active part number.
So a little new to PLC's especially Omron PLC. I have this machine from Japan that uses Omron CP1L which needed some modification. I made the modifications and uploaded it on to the PLC. When I try to put it in "run" mode it gives me the "Failed to change the operating mode the operation mode may be still changing in the PLC" error. After that the machine does not move even with the orginial plc logic. At first I thought it was my logic and so I double checked and did it again. Same thing occured. Has anyone experienced anything like this? How can I fix the PLC?
Thanks
