Using WindLDR
This section describes the procedures to use WindLDR for the AS-Interface system. WindLDR contains the Configure AS-
Interface Master dialog box to configure slaves and to change slave addresses, and the Monitor AS-Interface Slave dialog
box to monitor the slave operation.
For the procedures to select the PLC type and Function Area Settings, see page 28-8.
Configure AS-Interface Master
AS-Interface compatible slave devices are set to address 0 at factory and must be assigned a unique slave address so that
the master can communicate with the slave correctly.
From the WindLDR menu bar, select Configure > AS-Interface Master. The Configure AS-Interface Master dialog box
appears.
