Load the Script into the device. Open WINGATE and activate the device in the configuation
mode (see chapter 4.1, Configuration mode (config mode)) - an actuation message appears,
that looks in line with the following (example CL-PB):
RS-PBV1-CL (232/422/485) V7.31[30] (c)dA Switch=0x02FF Script(8k)="SSI"
Author="Deutschmann Automation" Version="V 1.0" Date=20.03.2008 SN=47110002 ID=2
Konfigmode...
If the note "Special Firmware (23) not loaded" appears, the note means that the firmware
does not support SSI yet. A firmware update has to be done.
After the update re-start the device -> now only the device’s actual actuation message
appears and not the note any more.
•
Bring the device into the data exchange mode (see chapter 4.3, Data exchange mode) ->
DONE!
