Perform a cross reference or search for DM6645 in the program to make sure it is not being written to in the program. This was the method of setting up the ports before CX Programmer come along. All DM memory is retentive so something is writing to it. Maybe the switch is defective? The correct procedure using CX Programmer is to make the change in the Settings dialog, then cycle power to the PLC.

OK, I tried this and it does ask for a serial number. I would call tech support and see if they can get you a download.  Alternatively, the manual shows you can program it with the panel keyboard. Ultimately, I would search out a newer panel. What is it connected to?

They may not support it anymore, but you can still download it at Rockwell's web site. Go to Download By Product, then type in DTAM.

If this is a practical application, I would highly suggest using NX I/O instead of Point I/O. They are similar in specifications and size. Omron will support CJ2 to NX 100%. If this is for fun, I can appreciate that. :) Rockwell does not play well with other EtherNet/IP scanners so you won't find any Rockwell information to use Point I/O with anything other than an AB PLC. You are correct that technically it should be possible as long as it adheres to the EtherNet/IP standard. The one problem I see is in an AB PLC the AENTR uses a single byte (SINT) for the output word. Yes, the output byte is necessary for the module setup. The CJ2 is not capable of dealing with bytes so I'm not sure of a solution there. The tag name should not matter. In the CJ2, it will evaluate to an address eventually, even if you are using Data Types in the CJ2. Rockwell uses Module Defined data types to automatically populate the controller tags.

You can do it offline as well in the Controller Tags > Monitor Tags section, then download to PLC. Chelton is telling you to create a new String array tag then populate it with your static texts. Then in your program COP String[x] to String.

It is Rockwell Software! Seriously, it's always been a little quirky but I guess they are in some way or another. I've had a lot of success using Keyence IP Configuration Tool. Side note:  I've read in other forums where Rockwell is taking measures to become more compliant with the EtherNet/IP standard. Maybe these version issues have something to do with that. <END GOSSIP>

What you described is correct. The rungs you show are identical to Michael's example. Logix and Sysmac PLC scans are the same. They scan from left to right and top to bottom.

I felt the same Bob as I read the headlines. Especially with the photos of the humanoid robots. So misleading and misinformative to those that don't know industrial robots, or the dangers. I hate to sound pessimistic, but this type of reporting has become normal our society.... in all genres of news. This is what the news is supposed to be doing. The fact that is it so late in reporting tells me there is some agenda here. I'm sure there is more to the story about corrective actions and preventative measures that we won't hear or read about.

It's not necessary to deregister the license. Just use the license number on your new installation. You'll need to input the email you registered to perform updates.

It seems to me that the Japanese PLC manufacturers are slow to release new products to the market. It also seems to me that they are generally more dependable than other manufacturers once they are released. Maybe that's just in my head. :)

Rockwell's Add-On Instruction is equivalent to Omron's Function Block. The Function Block you see in the help files is Function Block Diagram. When you create a new Routine, you can choose Ladder, Sequential Function Chart, Function Block Diagram, or Structured Text. So it's just a different method of programming.

I agree as far as comparison to the built-in ports. Have you seen the new NX-EIP201? I've only browsed the specs and haven't used one yet. The original poster eluded to performing this in stages so the CJ1W-EIP21 and NX I/O would be my choice with no question about performance. I usually like to compare cost vs. performance. The NX series tends to be most cost effective. 

You are very welcome! Glad we could help and good luck with the remainder of your project!

CJ2M Built-in Ethernet connected to NS by FINS - Tech and Application Notes - Forums.MrPLC.com I've never used NS Runtime but the communication settings look the same as the NS touch screens. Try the above connection procedure from Omron tech support. This is to configure the FINS Network settings on the PLC.

As far as the data export... Do you have some sort of SCADA at the plant? You would be much better off using some HMI software capable of FINS communication for pulling that data. You could write the data to a CF in the NS but that is a very old method that may be more trouble than it's worth. It's been many years since I've done that.

I'm going to assume the measured value in D1 is a single 16 bit integer. When performing totals or accumulations, I generally use doubles (32 bit). Just in case we break the bank of the 65, 535 limit on 16 bit integers.  In Omron PLCs, D and E memory are automatically retentive. They will retain their values after a power cycle.  In my example I will use D20 instead of D15. You can use whatever memory you wish but I just wanted some separation because it works better in my brain. Also, I want to use an even memory location number. This is due to using Doubles. Again this is just my preference. If we only use even numbers when dealing with Doubles, then we know not to mess with any odd number locations and we don't mess anything up. Also note the use of the "@" on the instructions. Preceding the instructions with "@" will execute the instruction for one PLC scan on the rising edge of the input condition (Measurement Complete).

If you want to use remote I/O, you may use any platform you wish. This is the beauty of EtherNet/IP (EIP) protocol. Please note EtherNet/IP is "Industrial Protocol" and is not the same as standard Ethernet. If you choose NX ("X" style rack configuration), you would likely have an easier setup and Omron support, although there are many reputable third party EIP remote units out there.  Also note, if you wish to use an NJ/NX programming platform, please take a look at the NX controllers. It looks as though you want to do this in stages but, if you are not replacing a CJ2, you won't necessarily require the NJ. There are a wide range of specifications on both NJ and NX controllers.  

I've never seen a CJ EIP Coupler Unit (or Bus Master) of sorts, which is what would be needed to head a remote CJ rack. The CJ2 brochure advertises using NX for EIP remote I/O. As pturmel suggests, the EIP21 would be the ideal unit for the main rack. This would give the flexibility of using Omron's NX, GX or even third party remote EIP I/O. Is there a reason you require remote CJ modules? CS-CJ-CP-Series-New-Functions-Brochure.pdf (omron.com)

I'm confused as to the problem you are having now. Are you able to format and install files to the card? Or having the NS lockup issue when installing to the screen?

HMI Sample Code - Forums.MrPLC.com There are several older versions here at Mr PLC. I checked downloads section at Omron's website and they only have the latest (8.95). I don't know how we could download select versions. It's probably not possible since the NS is obsolete. If you require a different version you could contact Omron tech support. They may be able to supply them without liability. I know there are some Omron guys on these forums but I haven't seen them in a while.

That would be my guess as well. Are you able to calibrate LH CAM and RH CAM so that zero is square for both cameras? If so, pull until LH CAM and RH CAM are equal, rather than some offset.  If I understand correctly.

I was trying to help. This guide shows "how to" exactly what you asked for. I have plenty of experience configuring EtherCAT modules although I've never used Smart Slice. Have you tried contacting Omron tech support? Did you acquire the ESI files? This is probably the most important part. I searched for them but could not find them. I would think the Smart Slice unit would be configured in Sysmac Studio but I don't know. 

Contact your local Omron distributor. The software is not free. A good relationship with a representative can go a long way though. 

From what you describe, it sounds like your ladder window is in Restore Down. (vs. Maximized). If it is Restore Down then all newly opened windows will be Restore Down. Conversely, when it is Maximized, all newly opened windows will be Maximized. In my experience, if you start a new project the window and tool bar settings will be default. If you open an existing project, the window and tool bar settings are stored in the *.opt file with the project name. This file is not necessary for the integrity of the PLC program so you can just delete it.
