In your program the target network number is set to 3 ?????? But you  are using network 1  

Which FX ? If it is an FX5 just use the simple PLC comms

Why not just test the demo program  Recipe_V_Ver2b_E.GTX Recipe_V_Ver2b_E.pdf

That doesn't matter the POU is the same

How do you want to control the inverter Serial (inverter protocol/modbus) or CC-Link IE Field basic ?

Always good to share info like that. You never know what you might run into tomorrow !!!

Well there is not time as far as I know but I attached is a small example I made where I created a delayed output using the Flicker block for the timing. You could do something similar for you application and use the counter value to display on the screen  Delayed_out.vls

That is simple. The POU are just the programs themselves but they are not send to the PLC if they are not linked to a TASK/ program File. So they are only compiled when you have dragged them to the MAIN file. As your Analoog POU is still red it either has not been compiled or it still has an error. If you want to get up to speed with Mitsubishi there are e few free online courses for FX and GX Works 2 http://www.mitsubishielectric.com/fa/assist/e-learning/eng.html en in het Nederlands kun je ook de vraag ook posten als dat makkelijker is  :)    

haha I now of places where there are still big A-Series PLC's still running for over 25 years.  On Quality nothing beats a Mitsubishi. Their Migration is also pretty good so i would suggest to exchange the CPU for a System Q or iQ-R. http://www.mitsubishielectric.com/fa/products/cnt/plca/ex/renew/renewal/index.html The program can be converted converted quite easily there is a test program you can download for free. http://www.mitsubishielectric.com/fa/products/cnt/plca/pmerit/renewal/case/support_tool.html      

True they do support .net as there operating system is their own but that is why it is more secure and starts up much quicker. As for the scripting yes the scripting is limited but  If you need that than your HMI doesn't support the features you need. GOT's can talk to many external Database directly  Why would you want to poke in the internal DB ?  

First of all why write to CF. Is the project that big ?? The message you receive is a standard message you get when the project was made with a new version of GT designer. If it looks like the project freezes at the first screen than you probably just don't have communication with your PLC.  When you changed the project to GT11 most likely the comm settings went back to default What are you communicating with ?    

"please install the standard OS" When you get this message you haven't installed the OS yet from GT designer. In your transfer setup. You get a list tree. The first section is the project. The seconde "Standard Monitor OS). You need to download this part into the GOT.  Download this into the Built in Flash memory. (Yo have to change the destination drive from SD to Flash memory before you see the complete tree)  

SOFT GOT should work also the GT simulator can be connected to a live PLC.

I always found the iX series to be kinda slow. But I tried the first few versions so that might be it. What is better about them in your opinion? 

Have you read the manual ? Have you set-up a the module under intell function module in GX Works 2 ? Which modbus devices  do you want to read/write ? Does the other device support all modbus Function codes ? We need a lot more information if you expect to get an answer .
