[Modbus]
Description
Initialize the ModbusMasterNode object and specify the mounting channel and corresponding node number.
Syntax
node1.attach(slave_id, bus1)
node2.attach(bus2)
Parameters
node1/node2
: ModbusMasterNode object.slave_id
: Specify the corresponding Slave node number; not specifying the number in TCP mode will make the number default to MODBUS_TCP_SLAVE (0xFF).bus1/bus2
: Specify the ModbusMaster object to be mounted.
Returns
bool: return true if successful, return false if not.
Example
#include <Ethernet.h> #include <Modbus86.h> ModbusMaster bus1; ModbusMaster bus2; ModbusMasterNode node1; ModbusMasterNode node2; IPAddress SlaveIP(192,168,3,59); void setup() { Serial1.begin(115200); bus1.begin(MODBUS_RTU, Serial1); // bus1.begin(MODBUS_ASCII, Serial1); Ethernet.begin(); bus2.begin(MODBUS_TCP, SlaveIP); node1.attach(16, bus1); node2.attach(bus2); // node2.attach(MODBUS_TCP_SLAVE, bus2); } void loop() {}
