Yes, however, in earlier versions of firmware having a client do this could actually cause Modbus TCP communications to halt due to the ECOM100’s attempt to process the requests and getting swamped by the amount of work required. Also, if a single Modbus TCP request was split between 2 telegrams, this could cause the ECOM100 to halt Modbus TCP communications as well due to it not properly handling the issue.
