Appendix C.6. “Illegal” Characters in Network Variable Names
Spaces Spaces may not be used in Network Variable Names. The driver automatically replaces all spaces with
underscores at start-up.
Brackets Lonmaker truncates a name from where a bracket is used. e.g. a name like nviTest[1]Input shows as
nviTest . Brackets are therefore not able to be used in Network Variable Names.
Appendix C.7. Service types currently supported for network variable messages
Currently the service type for network variable update messages is fixed to acknowledged service. Request-
response service is used for network variable poll and network management fetch messages.
Appendix C.8. Combining Explicit and Implicit
To ensure undisturbed communication between the network management tool and the FieldServer during the
commissioning, binding or monitoring processes, the timeouts of the explicitly addressed variables (Map
Descriptors) might need to be set to values lower than the message timeouts used by the network management
tool (LonMaker for Windows).
