I am new to the modbus communication. I trying to access the Edam 5029[img]
[/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,
