For any of the client Modbus networks (ModbusAsyncNetwork, ModbusTcpNetwork, ModbusTcpGateway), you should review its “network-level” defaults for interpreting/supporting Modbus data. These defaults are on the property sheet of the network-level component.
These settings apply to all Modbus devices in the network, unless overridden in the configuration of any device, using equivalent
properties. For more information, see Device-to-device differences.
