Hello Everyone,

I am new to the modbus communication. I trying to access the Edam 5029[img]>Zitat:

[code][img][/img][/code]

[/img] IO interface using RS485. I am using EASYSYNC usb2-5004-m usb to rs485 converter.

I am able to write to a coil or resistor but I am unable to read from coil or resistor. Everytime it is giving me error No response received from remote Unit/Unable to decode response.

I have already unable CRC check for EDAM 5029.

Here I am attaching my python code and relevent images for your reference.

Any guide will be helpful.

Thanks & Regards,
Bhavin
