Modbus TCP Plugin is not working

Open eyadalhanafi opened this issue 2 years ago • 9 comments

Hi. It seems there is an issue in Modbus TCP plugin. It doesn't read data from slave device. I used Modsim32 to simulate slave device.

I'm using Fuxa Version 1.1.6-688 Node.js v16.15.0.

MB and Modsim status

Hi, I would try with Node.js v14?

Hi, I tried with Node.js Version 14 and it is the same. You can give it a try as well.

I just tested with ModRSsim2, in ubuntu, windows and raspberry, work fine!

try to remove and reinstall node_modules

I removed Fuxa and reinstall it again but it is the same. Any idea what could be the issue?

something is still not clear to me: old versions worked and with the new one it no longer works? have you tried another modbus simulator (ModRSsim2)?

Hi, I have FUXA (version: 1.1.6-713) installed on my Raspberry Pi. In the attached video, the connection with modbus poll is modbus tcp. I got anxious about the new version of FUXA and decided to check it out. mb-tcp-1

Old version of Fuxa, Modbus was working smoothly. This happened when i installed the latest version. I will try with reinstall old version and check again.
