Modbus RTU Connection lost when i map 1 item

[KoBra]

OK because i found this too here on the forum
It's limited by ModBus standard:
max_read_bits = 2000
max_write_bits = 1968
max_read_registers = 125
max_write_registers = 123

Read also times out. Strange as it worked and i just altered the profile and the problem started.

I will reset the device and try again.
