LIN Bus aufbau für Mehrer Slaves

Hi,

How can I configure 5 ECU's same time for read/write/diagnosis in LIN
Communication.
Where my restbus(CANoe)is Master and ECU's is slave. Though we know the
LIN Bus has 1 Master and 15 Slaves. Is there any external
device/hardware without chaning the slave ID or software. Appreciate
here for your support.
