When using an Echelon U10/U20 USB or other Lon network adaptor for communication with a laptop and standalone WorkPlace Tech, not WorkPlace Tech Editor, you must change the default configuration settings. The default Lon Network Domain ID length (1 byte), Domain ID (18 decimal) and Subnet (254) in the AS-P conflicts with the defaults used by WorkPlace Tech.
Standalone WorkPlace Tech used on a Lon Network with an AS-P using default Lon Network communication settings
Lon Network configuration
Look at the LonWorks Network "Advanced" tab in the AS-P to determine the addressing information.
Open the WorkPlace Tech WorkStation Communication Settings and select LonWorks. Open the Change Address window
Select the "Manual Setup" radio button
Modify to match the AS-P Lon Works Network configuration. If a different Domain ID or subnet has been assigned in the AS-P, it will need to be assigned the same in WorkPlace Tech
You can now browse the LonNetwork from the laptop. If the MNL devices are assigned applications from the AS-P, do not modify the programs from the WorkPlace Tech Tool
