Look at PT> Communication setting. You must have at least 1 host setup under Serial A, B, Controllerlink or Ethernet (if available).

A quick look at the filetypes shows that *.cxe is associated to CP1E project files, which did not exist yet in CX-Programmer V1, as the CP1E series is only available since a year or 2. During the early days of CX-Programmer, files were usually saved as *.cxt (CX-Programmer text file) which later turned in to *.cxp (CX-Programmer project file). *.cxt is still supported. Try to set the filetype select list to "All files (*.*)" , and see if you can open the file.

Has anyone used this new Yaskawa Varispeed AC inverter? http://www.yaskawa.eu.com/en/products/inverter-series/varispeed-ac/introduction.html As opposed to conventional drives it does not have an intermediate DC switching circuit which greatly reduces the harmonic currents distortion expecially when using generator power. Without any additional DC reactor or chokes it claims to reduce harmonics to <6%. Together with reduced energy footprint, this might just be the electric AC drive of the future. Matrix.pdf

You can do this with a macro and PT memory. Upon pressing the valve button, depending on the valve you write the PLC variables to PT variables. Upon closing, you update the PLC variables with the PT variables. The is no template for this. I will see if I can find an example for you.

You probably also noticed that CJ2 series put A LOT more load on CX-P thant CJ1 did. Try copying an average CJ2 PLC in CX-P with some FB and rungs. It takes forever.

Check the box "Show all". That shows the other methods.

Although you have the licenses, the software still isn't freely distributable. Besides you are talking V4.0 which is pretty old. Locking this topic because it is in violations with the terms of service.

No not really... or really not. One would be to not have the NS poll data in the hosts but to write all data from the host to internal memory, but that would make it very hard to maintain the program. We are moving away from using NS terminals or NS runtime which has the same problem for projects with multiple ethernet hosts. Using more SCADA or other HMI brands to overcome this.

I was wondering if anyone has a trick to overcome the problem that when one or more Ethernet hosts setup in a single NS terminal go offline, the terminal becomes pretty much inoperable, due to the great lag and communication errors. Especially when trying to navigate trough screens where objects direct to the offline host, the performance is extremely slow. I know about the comm auto return and timeout parameters but they don't seem to help much, although retry is set to 0 and comm auto return to ON, it keeps trying to connect to the offline host when navigating screens. Sure the screen has to try to reconnect but it should not influence the performance as much as it does now. How do you guys handle this?

No I don't recall running into this, regular come across projects with CJ2s networked by EIP. You are not just limited to 1 PLC when connected by USB, you can drill into any EIP PLC on the network easily just as with Toolbus across Controllerlink.

Hi Bob, what connection method do you use, USB, Ethernet I/P, FINS? I don't know this behaviour but it might be worth trying another connection method.

Also had a funny glitch a few weeks ago. After I installed CX-Supervisor on my laptop, the complete I/O table was nowhere to be found in CX-Programmer for CJ2 series A known bug, and there were a few fixes mentioned on MyOmron but none of them worked for me.. in the end had to uninstall (be sure to use the CX-One remover utility instead of Windows software management!) and reinstall CX-One. Especially with all the updates it is quite a cumbersome job...

When you press connect in CX-Programmer, do you see any comms LED flickering on the PLC CPU?

You might want to mention which type of network you are talking about and what hardware..

I guess this is Japanese logic

Set dipswitch #5 to ON position. This defaults both the RS232 and peripheral port to 7,e,2@9600. When OFF it uses settings in the PC setup. Power cycle after changing dipswitch position and try again.You can also try auto online in CX-programmer which scans the port at several different baud rates and protocols.

Then again, a sharp eye can also be your savior

I strongly suggest you start reading some manuals - its all in there. Memory mapping down to the bit. Its not like you think. Input channel starts at CIO3300, but the first word is status area for the smartslice PNT unit. So your first digital input of the ID4-1 is CIO 3301.00, second input 3301.01 etc. Outputs do start at CIO3200 for the first unit, so your first output of the OD4-1 would be 3200.00, second 3200.01, etc. Some but not all units are assigned memory adjacent. Did you see my screencopy? You can also see the memory mapping there. It clearly shows what units are assigned to what CIO word. See the download links in the FAQ from my sig to find the manuals.

Hi Bob! Is this the combined temperature input unit? I remember a few weeks ago my colleague called me in the workshop and he was struggling with this one too.. erratic readings although everything seemed connected ok and set correctly.. darn it I don't remember exactly what it was but I believe, it had to do with an unusual procedure to set the DMs using the IO table. I checked and transferred the unit settings through the IO table a hundred times, but only after I first uploaded the units settings, set the parameters and transferred it back, I worked. Or something like that. Call me crazy but try it, upload the settings after you transferred, see if it changed. And if you find out: tell me!!

By default, input area starts at CIO3300 and output area at CIO3200. You can use CX-Configurator FTD to check what memory addresses are assigned to each I/O module.

How did the application example project provided in a download link in an earlier post work out for you? I can't believe I am attaching this... Tip 51_ How to Use the TD 200 Operator Interface with an S7-200 CPU.pdf tip051b.rar

I would take a black marker and write "hello world" on the screen. That should do the trick. Seriously, what have you tried? What results do you get? What are the problems? What have you tried yourself to get rid of the problems? What did you expect, out of the few words we are supposed to provide an answer? What are we magicians?

The only problem I have is that the status information link is done over the EIP unit by FINS and it turns out it cannot have the IP changed. So we would require a secondary ETN unit to run the link. Quite a cumbersome setup..

I checked the manuals but it seems it can only be read by CX-Programmer and is not available in the user memory area.. would be useful though for exactly this kind of purpose. May I ask how you did the IP switching? I have a setup where I have 2 CJ2M-CPU31 with each a Profinet master to control 3 Profinet smartslice units using 2 Hirschmann MRP switches. The IO controller redundancy is working using the Profinet redundancy function block but the IP switching of CPU seems to require an additional ETN unit because the IO controller redundancy link does not allow switching IPs.
