Greeting,
I would like some help regarding the reading of the distance sensor with RS485 communication.
I am using V570 PLC, COM 2, 115200 Baud rate.
The sensor ID is 1.
On the monitor I have a situation like in the picture below


Can someone tell me what I'm doing wrong because I can't read anything
Grateful

Please post your sensor model # or pdf manual (modbus communication manual).

Please post your com port configuration.

Please note some sensor provide non standard modbus

Yes, I used Benewake's original software for RS485 and I have a connection with the sensor
i.e. I can configure it and get distance data graphically and numerically. In what I get from the monitoring of my PLC, after 59 59 there is information about the distance, then the quality of the data, and after that the temperature inside the sensor. The data is alive, that is. responds to changes. Addresses 0, 1 did not give a result. ?????
Thank you!

Hi,

you must enable modbus on this sensor before try to read it via PLC.

Original software do not use Modbus for talk with sensor.

This text from your manual.

1) Under RS-485 serial link mode, enable Modbus protocol:
5A 05 15 01 75 // Enable Modbus protocol
5A 04 11 6F // Save setting
