  4. QJ71C24N-R4 communication (Autonics TK Series)

    Can any one explain about this? How do read registers from temperature controller? How do i write registers to temperature controller? I know the registers that i want to read from the communication module eg. 301001(03E8) but how do i put in the plc?
  5. Hi all. 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:  TK4 Settings: 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: CH2: Operating: Independent 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.  TK-Q02H_RS485_EN_Technical_support_180823_W.pdf
