שאלות נפוצות

Issue

After select the secondary connection in Modbus TCPIP Driver, will VJD runtime switch to the backup IP if the PLC is in stop status？

Environment

Vijeo Designer 6.2.

Resolution

Only a communication failure is detected on the primary IP, then VJD runtime will switch to the backup IP. If the PLC is in stop status but the communication is still active, then runtime will not switch to the backup IP.

User can consider to change the Equipment's IP address in script if the PLC in detect is in stop status.
Here is an example to change the Modus TCP Equipment's IP:

int[] ipAddress = {192, 168, 1, 10};

ModbusEquipment01.openConfig();

ModbusEquipment01.setProperty("Con_IPAddress", ipAddress);

ModbusEquipment01.commitConfig();
