Hello everyone,

I am working on an Arduino-based 10 IOs PLC. IDE was installed according to the user guide. However, when I tried an example for 10 IOs PLC Family: Ethernet->WebServer, the serial console returned:

"Ethernet shield was not found.  Sorry, can't run without hardware. :(" 

Is that faulty hardware? Anyone can help?

Thank you very much,

Ha


Update: 

Never mind. The PLC needs an external power supply for the shield to work.

Hello,

You can try these examples that use WIFI so that you don't need an Ethernet Shield.

Hope it helps.

Thank you for your reply. I do have another issue with the example code ModbusTCPSlave from your GitHub. It throws a lot of errors regarding the timers at compilation. Perhaps, the example was not revised to support 10 IOs PLC Family?

Here are the errors:

Arduino: 1.8.6 (Windows 10), Board: "10 IOS PLC Family, 10 IOS PLC"


C:\Users\HATVS\Documents\Arduino\libraries\arduino-Tools40-master\src\Pulses.cpp: In function 'void startPulses(int, uint32_t, uint8_t)':

..............

Has anyone successfully compiled the code for 10 IOS PLC?


Thank you,

We are currently working on solving this problem. Make sure that the 10 IOs PLC family of the "Industrial Shields megaAVR Boards" has been selected and not the "Industrial Shields ES32 modules", as it can be misleading . Meanwhile, you can contact us at [email protected] in order to get a fast solution!

Sure, there is only one option in Arduino IDE: "10 IOs PLC family" under the "Industrial Shields megaAVR Boards".

Hello,

In order to work properly with our devices it is required to power the PLC with an external 12/24 Vdc power supply.

Thanks a lot for the feedback provided. If you have any other question do not hesitate in contacting us at support!
