We are again facing an issue with one of the LR140, in which we can’t be able to read the modbus registers.

We followed the same instruction which you have given us as per the below email.

The R8, R6, R10 is removed and still we are getting the values as FFFFFFFF.

Any idea to solve this issue?

1、If LR140 is connected to a modbus device with terminal resistors, it does not need to remove R8，R6 and R10
2、If LR140 is connected to a modbus device without terminal resistors, it need to remove R8，R6 and R10 of LR140.
