open_connection

This is a function for connecting with the robot controller using TCP/IP communication. As TCP/IP is internally fixed, there is no need to designate it separately. When two or more robot controllers are used, the IP address should be changed in the T/P application.

Definition
DRFLEx.h within class CDRFLEx, public section (line 572)

bool open_connection(string strIpAddr = "192.168.137.100", unsigned int usPort= 12345) { return _open_connection(_rbtCtrl, strIpAddr.c_str(), usPort); };

Parameter

Parameter Name	Data Type	Default Value	Description
strIpAddr	string	“192.168.137.100”	Controller IP address to connect.

Return

Value	Type	Description
0	int	Error — failed to establish a TCP/IP connection.
1	int	Success — successfully connected to the controller.

Example

CDRFLEx drfl;

bool bConnected = drfl.open_connection("192.168.137.100");
if (bConnected) {
    SYSTEM_VERSION tSysVerion = { '\0', };
    DrFl.get_system_version(&tSysVerion);
    cout << "System version: " << tSysVerion._szController << endl;
}

This example connects the external PC to the robot controller using its IP address. When the connection is successful, it retrieves and prints the controller’s system version information.
