If value_map is not set the interface will try to set the Modbus register to that value. If a value_map is set for a register the interface will reject raw values sent via MQTT. This will be used to translate between human-readable values via MQTT to raw values via Modbus.
MODBUS POLL GITHIUB SERIES
Must be 'holding' or 'input'.Ī series of human-readable and raw values for the setting. The Modbus table to read from the device. See for details.Ĭontrols whether the value of this register will be published with the retain bit set.Ĭontrols whether this register will only be published if its value changed from the previous poll. Values published to this topic will be written to the Modbus device. This is the topic to which the value of this register will be published. Many modbus devices enumerate registers beginning at 1, so beware. The decimal address of the register to read from the device, starting at 0. This section of the YAML lists all the modbus registers that you consider interesting. pub_topic: "external_temperature " address: 13015 type: int16 pub_topic: "load_control/optimized/end_time " address: 13014 json_key: minutes pub_topic: "load_control/optimized/end_time " address: 13013 json_key: hours pub_topic: "first_bit_of_second_byte " address: 13001 mask: 0x0010 pub_topic: "forced_charge/period_1/start_hours " set_topic: "forced_charge/period_1/start_hours/set " pub_only_on_change: true table: 'holding ' address: 13142 pub_topic: "forced_charge/mode " set_topic: "forced_charge/mode/set " retain: true pub_only_on_change: false table: 'holding ' address: 13140 value_map: This will be very inefficient and should not be used in production as it will saturate the link with many read operations. By setting scan_batching to 1 each register will be scanned individually. In some modbus devices a single invalid register in a read range will fail the entire read operation. This setting can also be helpful when building a modbus register map for an uncharted device. Modbus read operations are more efficient in bigger batches of contiguous registers, but different devices have different limits on the size of the batched reads. This library transparently decrypts the modbus comms with sungrow SH inverters running newer firmware versions.
Setting this to 'sungrow' enables support of SungrowModbusTcpClient. See section 4.4 of the Modbus spec.Īllows variants of the ModbusTcpClient library to be used. In many Modbus devices the first register is enumerated as 1, other times 0. This offset is applied to every register address to accommodate different Modbus addressing systems. The number of seconds between polls of the modbus device. The port on the modbus device to connect to.
Presently only modbus TCP/IP is supported.
The IP address of the modbus device to be polled.

QModBus also includes a bus monitor for examining all traffic on the bus. A graphical user interface allows easy communication with ModBus slaves over serial line interface.
