Has anyone written a driver to comunicate with an ADAM 4000 module using Modbus portocol over RS485?
Hi!!!!! I am trying to comunicate with an ADAM 4000 (4068) module using Modbus protocol. I send the message through the serial port RS232 because I am using other ADAM module that converts RS232 to RS485, so RS485 is not a problem for me!!I think that the problem is the frame that I am sending!!!The ADAM module doesnt respond me!!!! Has anyone worked with this protocol!!!!!!!! I am looking forward to your answer ;)!!! I need help!!! Ciao!! Graci
