Hi, I'm using the same code for this on .Net <<(
])>>. I have a PLC connected to a PC through Modbus RTU (RS485). Between PLC and PC I have a RS485-RS232-USB converter.
I'd like to know how this program could read and write memory registers of 4 bytes (2 words) size. I need to handle memory registers with float data type and others with negative values.

This is the link with the PLC registers <<(
