Hello everyone. I have a doubt about how to read Q in Modbus. I found a pdf that the user Scorp send to the German forum. In that document it looks like if i want to read the Q1 value, i need to read the register 8193, Q2--> 8194 and so on. But in the data transfer table of the Modbus connection, i see that is possible to assign Q1 to (for exemple) Coil=5. Does it mean that in this case, to read Q1 i would need to send a request to receive data from the 5 register? What happens with V0.4 that according to Scorp document is stored in the 5 register? I've appended an example that user ixo65 added in other discussion with tha change of data trasnfer table that i've explained. I'm looking forward to hearing from you. Regards.
