I am new to Autonics and Mitsubishi.
I am trying to read and write the data of an Autonics TK series temperature controller using RS-485 with QJ71C24N-R4 coupled with Q00UCPU.
I have the hardware setup as attached images.
Software setup are as follows:
Communication address: 01-99
Communication speed: 38400bps
Communication parity bit: none
Communication stop bit: 2
Communication Response waiting time: 20
Communication write: Enable
Mitsubishi Intelligent Function Module:
Data Bits: 8
Parity Bit: None
Even/Odd parity: Odd
Stop bit: 2
Sum Check code: None
Online Change: Enable
Setting Modifications: Enable
Communication Rate Settings: 38400bps
Communication Protocol Settings: Predefined protocol
Task to be carried out:
1. Read SV
2. Read PV
3. Write SV
I have the address for the modules but I am not sure how to communicate or the program which allows to reading/writing. I had tried to follow the attached PDF but i cant key in the first line as there is a bit with "G450" which has an error stating "the device No. is over usable range" and "An unusable device has be designated".
I hope someone here could guide me in writing the program, or any reference for me to follow.
