DA clients. All data points with the OPC check box activated will be exposed. Connect to the L-INX using the URL http://192.168.24.99/DA , given that 192.168.24.99 is the IP address of the device. Note, that by default, writing to
OPC tags needs basic HTTP authentication using the password for the operator user. This is
‗operator‘ by default.
2.7 Reset to Factory Defaults
In case the password of the device or the PIN code of the LCD UI has been forgotten you may need to reset the device back to factory defaults to gain access again. On the L-INX models 10X, 11X, 20X, 21X press the service button and power-cycle the device. On the
L-INX models with the jog dial press the jog dial and power-cycle the device. Keep the button/jog dial pressed until the port LEDs illuminate orange permanently. Release the button/jog dial within five seconds from that time on to reset the device to factory defaults.
