In addition to the motion control instructions, you are likely using an Interrupt instruction as well due to the registration eye. Take a look at W480 (software user manual). This will point you to the instructions you'll find in your program. It also does a good job of describing the high speed I/O functions. 

You cannot create a CX Programmer project for the C120. It can however upload and download backup files. I don't think this is your best option though since you would not be able to view the ladder program. I cannot confirm that the C120 can communicate via CQM1-CIF02 and C200H-IP007 with any PC software. I don't think it will but we'll see if someone older than me can confirm this. I believe you would need the C120-LK201 and a serial cable. Note:  Just because the handheld will work doesn't mean PC communication will.  I would use the PRO15 and write the program down in mnemonics. Most likely, the password is not set on the PLC. Press CLR > MON > CLR to get to the mnemonics list.  You say the Run light does not come on. I assume you tried switching the PRO15 from PRG to RUN?

You're welcome. I don't like it either.

PCON_SysmacStudio_EIP_Structures.xlsx I didn't create these but I copied them from a working program.

I'm sure Rockwell has a software package that could specify this for you. :)

In short, yes. Not necessarily with GX but with other industrial devices. I guess the formats can be very strange to Windows. I don't have an intimate knowledge of the issue.

Check the DIP switch settings according to the manual.  Are you using both Option Ports? Certain combinations won't work, if I remember correctly.

I don't know much about NMEA data but a quick search shows that it is RS232C. The CJ serial port can read and/or write serial data in raw format. Have a look at these examples. TXD-RXD Quickstart Programs - PLC Sample Code - Forums.MrPLC.com

Typically a software package like that will be setup to read data from a PLC via EtherNet/IP or FINS or whatever driver is available. You shouldn't need to write ladder to send data. For the NJ you will need to set the variable attribute to Publish Only for the tags you wish to be read.

If the screen was originally programmed with the DOS software, then you'll need to upload it with the DOS software then perform a conversion from the project file. I forget the file extensions. I thought that NTST gave these warnings and instructions but it's been many years since I've dealt with it. NTSS233 - Demo Software - Forums.MrPLC.com  

Do you have CX Programmer? I would check the address the encoder position is set to in the NT20 then monitor in CX Programmer. Make sure the data type is correctly set. For example, if the display object is configured to display BCD and the PLC value is Decimal, this will cause display issues as well.  I would also troubleshoot the saving issue in CX Programmer. You will first need to understand how the 'sets' are saved in the PLC.

The "***" that you see indicates the value has more digits than the display object can display. I don't think there is anything wrong with the NT20 except for the dark horizontal lines. That will only get worse. You likely have a problem with the encoder connected to the PLC. When you move the machine, do you see the encoder inputs turning on? I'm not sure what you mean about the cam settings. Check that the PLC RUN light is on first.

Network Configurator for CIP Safety is a different software package. It's a bit confusing. I don't know that it is a free download. You should contact your local Omron distributor. Note:  The network you view on the software will show an EtherNet/IP tab. With the CIP safety, you'll also see a DeviceNet tab.

Are you sure your device isn't giving you 4.05mA?

I guess I misunderstood the question. I thought he wanted to know if the built-in port would be the same as the module. When, if fact, the CPU11 doesn't have a built-in port. I need new glasses apparently. Anyway, the answer is the same as both the EIP21 and the built-in ports.  We've used the application you refer to with the NJ501 as well. This was a recommendation from Omron back in version 1.09. I'm not sure if they have increased it's capabilities since then.

Yes, this can be done in the same way as the CJ1W-EIP21. The specifications are nearly the same. In fact, they use the same manual.  Cat. No. W465. I can dig up an example if necessary but I believe you have what you need.

I assumed you were referring to the eHMI_ items. You are correct that you will have to use the VB.Net documentation. Knowing which items will work with the screen has been trial and error. 

In the Ethernet/IP Connection Settings > Tag Set section > Check the Output at Fatal Error column. It should be set to 'Cleared'.

NA-series Programmable Terminal Software User’s Manual (V118) Section 4. It is installed on your PC with the software. C:\ProgramData\Omron\Sysmac Studio\StartMenu\Sysmac Studio\Manual\NA Series

Regardless of the method you use to shift the data, you may still have the issue that is being mentioned by the other posters. Possibly a 'double shift'. As already mentioned, you could latch it in then reset it after some time to prevent chatter. If that's the case.

Most likely, you are using the built in HSC functions on the CP1H. High Speed Counting is performed in the PLC hardware. Using standard MOV instructions in the cyclic task are not fast enough to read the precise encoder position.  Take a look at the CTBL(882) and/or INI(880) instructions. The INI(880) instruction will also be used to reset the counter.

CX Programmer and Sysmac Studio are two different platforms. While Omron gave us some hardware compatibility for upgrading purposes, simulation will not be possible. Also, you cannot copy a program from CX Programmer to Sysmac Studio. CX is address based and SS is tag based. I heard that Omron has a tool to convert but it's not publicly available. Maybe you can ask Omron to do it.

This is most likely an Omron question. I wouldn't think so. I say this because, even the NJ/NX series are not field upgradable. Omron can upgrade them. 

Even if that link worked, the version would be very old. Go to Omron's website and download the latest version for free.
