Wasan liked a post in a topic: Modbus Addressing in Weintek HMI
-
@Wasan Thanks. It was just silly mistake had been done by me in wiring. And as far as i m using RS 485, i am not getting data on both PC as well as HMI. Either on one i can fetch that. I do some changes in software configuration of Addressing, i mapped MODBUS address into local HMI(LW).
-
@Wasan Thanks for supporting me, today finally i got my data corresponding Temperature.
-
@WasanThanks you for replying.Yesterday i got the data of temperature on on PC but still on HMI screen it is not transferable and shows same error as "Device no respose." Here by, i am attaching mannual of my I/O scanner. KH 7014-18 MANUAL.pdf
-
@Wasanabout communication parameter i attached one screenshot of baseblock for serial communication. Yes, i data should be shown on HMI or Baseblock but i shouldn't. I cant find the my mistake so if you can help me to tuck out out of this problem then it would be pleasure for me. Thank you in advance.

@Wasan I am using Modscan32 in which i got the data of corresponding register, but not in HMI as well Baseblock also shows me like "No response". i am using 2 wire Pt 100 temperature sensor.
-
i did it in same way as you do but still i get same error.
-
Pt 100 and corresponding data receives receive in 40001. so how can i do addressing in Easy-builder of it.
-
Yes, Exactly i want to receive data from temp sensor on HMI screen via RS 485
-
Modbus addressing in Weintek HMI to poll data from Temperature sensor through RS485. In my system i have connected Temperature sensor to I/O Scanner has output in terms of RS-485 which directly connected to COM3 Port pin. No. 6 (as Negative) & 9 (as Positive) of HMI (Model No: MT8071iE) and HMI connected to PC via ETHERNET. I want to read temp on HMI screen via MODBUS protocol. So, can you please provide me instruction about addressing of MODBUS register in Easy-Builder Software so can read data of corresponding register. Because when i do compile i got an error like " Device no Response". I hope i will get reply from your side as Fast as possible to overcome this problem. Thank you.
