Bob, Did you enable each area that you want to use?  By default, none of the areas are enabled.  See check boxes below: Note that there are multiple pages in this window, press the next button to access all of the $SB and $SW options.

The .swp file that was attached was in fact a CxxH, not a C200H. The error message that you were getting was correct. It was a C20H program. Just in case you wanted it anyway, I went ahead and converted it from a CxxH to a C200H in Syswin and then imported it into CX-Programmer. I have attached the file below. D16135P_C200H.cxp

You can definitely go online with a C200H and CX-Programmer.  You need to have an LK201 RS232 serial module though.  There are two types:  the card type that plugs into the backplane like any other module, or the facemount type that plugs onto the front of the CPU01.  

Do you have a routing table in the PLC? What is the IP Address of the PLC?  Of the PC?  Do you have a FINS Node number set for the CIF41 (Browser setup)?  if so, what is it?  

You can reference the variable directly from the HMI.  See below: Enumeration setup: Variable in NJ: Mapping in NA: Setup of data display: Simulation:

It sets up exactly the same way.  Just have both devices in your Network Config, like this: Just repeat the process for the built in CJ2M EIP port that you used to set up the CJ1W-EIP21 in Network Confgurator for EtherNet/IP.

Changing the DM numbers does not work.  The IP address does not change at the point that you change the DMs and when the ETN21 is restarted, it puts the original numbers back in the DM area.  I would think that you would have use a FiNS command to do this. The error would not be a big deal for the PLC as it is a non-fatal error, but would cause issues with FINS communications on your network.   The EIP masters can both have tag data link communications established with inputs only.  Outputs can only be assigned to one master.   You could perhaps do something with explicit messaging for the outputs.  

After you write to the csv card, you can FTP to get the file.

You have to use Network Configurator for EtherNet/IP.  It is included with CX-One. You can connect to the controller and then to the EIP21 module to upload the datalink settings.  Section 1.4 in the guide above describes using the Network Configurator for EtherNet/IP. After step 1-4-2 in the process you can connect to the network and upload from the network to see what connections are already configured.  Then you can skip adding the CJ2 PLC and just use what you have uploaded to follow the rest of the procedure.  

If you mean that you need to know if there are any EtherNet/IP nodes exchanging data with the EtherNet/IP master, you can use Network Configurator for EtherNet/IP.  You can find it in the CX-One folder in the start menu.  Once open, you can connect to the network and upload any connections that are made.  

A little trick for seeing the Target variable.  Place your cursor in one of the Target Variable fields and hit CTRL+Space and it will show you the options.  Note that the originator variables will need to be the same size as the target variable assemblies.  You will need to declare them as Input or Output variables (under network publish column) in your global variable table and then register them on the Tag Set tab (Registration all after creating variables in Global Variables).  

Where I saw the extra space was in the equation for the Global Event that he had.  I think it just triggered him to just remove all references to the _HMI_CurrrentPageIndex and start over.  

How are they communicating?  Ethernet/IP Datalink (implicit communications)?  

It sounds like his hardware is good as he says he can upload / download through the port using CXP.  If Kepware's Toolbus driver works, then it should be a matter of configuring Kepware to get the data that you need.  Maybe someone in here is fluent with Kepware.

This was resolved.  @Nate Hammersmith posted in the other thread: https://forums.mrplc.com/index.php?/topic/39155-comments-are-lost-in-transfer-from-during-sync/

Good point.  It seems like that should work.

@mr_electrician, I don't have 2 NA screens to test with.  Everything that I have tried seems to work in simulation (1 screen at a time).  Can you share your code?

From DM:   Hi; my name is Metin , I live in turkey. unfortunately I have a problem that I could not reach a conclusion here. I hope you can help. I need to communicate with CJ1W-ETN21 with a device via modbus tcp and read information. I downloaded ready-made protocols on omron site, connection is established but I cannot read. I tried the attached protocols. the device I am trying to communicate with :  https://www.gmweighing.com/products/weighing-indicator-m02  I will get the weight information from the weighing device. Thank you in advance for your help. MTCP_ETN_Client.zip

Can you attach the code that you have attempted?  

Can you show us how you are doing it?  If you are using a variable for the setpoint, make sure to show the monitored value of that variable.  

Confirmed:  I just tested this with the hardware and both global and local variables DO retain their values when the program is stopped and also after it is restarted.  

I do not.  Sorry.

The message says you need to reinstall CX-Programmer (CX-One).

It is in a font (maybe Chinese?) that you don't have on your PC.  You need to find out what the font is, get the font, then you may have a chance of translating it online.

Yes, that is very likely.
