MODBUS POLL RESPONSE 255 SERIAL

See general documentation about serial port configuration to configure the serial port correctly. Otherwise you might encounter errors preventing all communication. With serial Modbus slaves, configuration of the serial port in openHAB is important. Other than the things themselves, there is no binding configuration. Typically one defines either tcp or serial bridge, depending on the variant of Modbus slave.ДЇor each Modbus read request, a poller is defined.ДЇinally, one ore more data things are introduced to extract relevant numbers from the raw Modbus data.ДЇor write-only communication, data things can be introduced directly as children of tcp or serial bridges. Is child of poller (read-only or read-write things) or tcp/ serial (write-only things). Analogously, is responsible of converting openHAB commands to Modbus write requests. Thing for converting polled data to meaningful numbers. One poller corresponds to single Modbus read request (FC01, FC02, FC03, or FC04). Thing taking care of polling the data from modbus slaves.

The binding does support Modbus RTU over Modbus TCP, (also known as 'Modbus over TCP/IP' or 'Modbus over TCP' or 'Modbus RTU/IP'), as well as normal 'Modbus TCP'.

The binding does not act as Modbus slave (e.g.

Please note the following caveats or limitations The binding can also write data to Modbus slaves using FC05 (Write single coil), FC06 (Write single holding register), FC15 (Write multiple coils) or FC16 (Write multiple holding registers). This polled data is converted to data suitable for use in openHAB.ДЇunctionality exists to interpret typical number formats (e.g. The binding polls (or reads) Modbus data using function codes (FC) FC01 (Read coils), FC02 (Read discrete inputs), FC03 (Read multiple holding registers) or FC04 (Read input registers).
