Which firmware version are you using? You can also try reading from a script (change IP as needed) and post what you get in Logs tab:

Code:

require('luamodbus')
mb = luamodbus.tcp()
mb:open('192.168.0.1', 502)
mb:connect()

-- mb:setslave(1)

r1, r2, r3, r4 = mb:readregisters(4201, 4)
log(r1, r2, r3, r4)
