Post by nulltrace on Modbus TCP Server connection is ESTABLISHED but all holding registers are value 0? ^{CODESYS Forge talk (Post)}
it works pretty well on codesys-version using device-tree and channels. heres the twist: each uid should be represented as a device, which in your case, it isn't. on the other hand, you found a solution which already works fine. Happy Modbus'ing
