Description

Initialize the ModbusMasterNode object and specify the mounting channel and the corresponding node number.

Syntax

node1.attach(slave_id, bus1) node2.attach(bus2)

Parameters

node1/node2: ModbusMasterNode object.

slave_id: Specifies the corresponding Slave node number. In TCP mode, if the number is not specified, the number will be preset to MODBUS_TCP_SLAVE (0xFF).

bus1/bus2: Specifies the ModbusMaster object to be mounted.

Return

bool: If successful, return true, otherwise return false
