The Self-documenting String for a
Network Variable can be up to 40
characters wide. If specified for a Floating point or
Integer SNVT then NV Updates
with values lower than specified
here will not be written to its
relevant Data Array location.
Server NVUI can be grouped with
Client NV Update types and
NMFETCHC. Server
NVPO can be grouped with Client
NV Poll types and NMFETCHC.
If specified for a Floating point or
Integer SNVT then NV Updates
with values higher than specified
here will not be written to its
relevant Data Array location.
Required for Throttling Mode: This field specifies the
minimum change needed for a Network Variable’s
value to invoke an NV Update.
