I ask why the analog expansion module A0602 is not detected in plc ide 1.0.6.
Has anyone managed to make it work?
I’m having the same issue
I made some progress. Use the Arduino IDE and update your expansion modules. Opta user manual walks you through the update. In the Arduino IDE the analog expansion is recognized.
In the PLC IDE it now knows the Analog expansion is there, but the detected config is blank. So bottom line not recognizing the analog expansion correctly.
exactly, it tells me when I upload the program via plc ide that the plc configuration is incorrect.
I sent the email to arduino to understand if there will be a new software release, pointing out the error.
Any reply from Arduino?
Version 1.06 is not compatible with the analog module, Arduino should release a new version in the coming weeks.

I confirm, from PLC IDE version >= 1.0.7 will be compatible
Apologies for being late on the release

Thanks for confirming!
Hey jlchapman, can you please give a brief note on how you got the Arduino IDE to recognize the analog expansion module / verify access to the pins? v1.1 of the PLC IDE is still having trouble recognizing my expansion module and I need to make some headway on my work project 
Hi. I got the Analog Expansion Module a couple of weeks ago but I still cannot use it. Do you have an estimated date for when the new version of the PLC IDE that supports it will be available?

Any update on 1.0.7?

Hi, it looks like it's available now on the download page of the PLC IDE

Has anyone had success with A0602 using PLC IDE 1.0.7?
I've tried using together with the two digital expansions, updated the firmware and could connect to the A0602 OK.
But when I download a program to the Opta, the status bar states "Not Running" and I when I check there is a message in the dowload window stating something like "Unable to reboot PLC"
When I remove A0602, everything works OK again
I have Arduino plc ide 1.0.7 and I had no luck using the A0602. After upgrading firmware on expansions with Arduino ide, I can detect the A0602 with Arduino plc ide but if I try to send ladder logic to it I get this pop up message "ERROR: Unsupported I/O Expansion type: Arduino A0602 - Finder 8A.26_1", if anyone found a fix let me know, otherwise I think I'll have to wait on future versions of Arduino plc ide or firmware will have to fix this issue. Note: The analog expansion works with Ardunio opta blueprint examples using ardunio ide.
This issue happen to me too. You need to uninstall PLC IDE, delete the folder T in app data, and reinstall again. Already send this information to Finder.

Hello,
Not work for me...
I've got something strange, when I scan Expansions, configuration is matching
but when I upload it doesn't work!
--- Start compilation (PostBuild) 14:50:38 --- Sketch generated, is changed: false WARNING: Fast period may not be enough for the configured I/O Expansions: consider increasing it --- End compilation (PostBuild) 14:50:38 --- ERROR detecting I/O Expansions ERROR: Project I/O expansions configuration is different from the detected one. Can not download ERROR detecting I/O Expansions
Start to put fast task at 50 Ms.
Have you update the firmware of the expansion?
Happen to me too, try reset the board.
Try with one expansion by time. I
know is very frustrating.
Waiting for codesys.

Yes, the module's firmware is up to date.
Reducing the fast task cycle to 50ms works on small programs. But as soon as I configure the RS485 port it no longer works.
Yes indeed, it's very frustrating to have thought that the ‘PRO’ logo would allow me to have a hardware and software solution that had been tried and tested by ARDUINO before it was marketed...
50 Ms are recommended to Arduino if you are using analog expansion. I have no issue on modbus RTU at this speed.
OK, I'll test it with another slave device. I think my sensor isn't good quality.
