How to read data from RS 232 device?!

Postby op-ixa » Thu Jul 21, 2016 12:03 am

Hi

I am new to Winlog 3.1 and I have watched your tutorials on youtube to have a general idea how it works.
The problem is that I have connected a device, which works with rs 232 port to measure the water level via a sensor. The device is connected to the notebook through a usb data adapter. I made a test in the Modbus RTU and it seemed to had a connection but then had read errors 1 2 3 etc.

How can I read the data (water level) from this device?!

Thank you in advance
Best Regards

Dear Sir,
have you a modbus address and modbus register of your devices? Can you post your application? Export from Project Manager -> Project Menu -> Export.

Best regards

Hi

The device is a data-logger and works with Minilog Software (similar to Winlog 3) but I wanted to connect and read out the data with Winlog 3.
I am sending you the Project in zip file and the link of Minilog for more info (Manuali > VEDO/MINILOG/MYLOG):

PS: I don't know the modbus address or register --> that is the problem.
Thank you in advance
Best Regards

Dear Sir,
we can comunicate without modbus address. Are you sure that the Modbus protocol are supported? In manual is not mentioned.

Hi

I want to buy a device that uses the protocol OPC.
Does Winlog access the hardware (device) with OPC protocol?! If so how does it work?

Best Regards

Dear Sir,
Winlog can communicate with OPC DA 1.0, 2.0 and 3.0
