With this message, the Host defines a set of limits for a single variable or a series of
variables.
DATAID may be any value, and is ignored by the Equipment.
VID must specify the Variable ID of a Variable for which Limits Monitoring is allowed.
LIMITID must be between 0x01 and 0x07. It specifies one of the seven allowable limits
for the variable.
UPPERDB and LOWERDB must match the value format of the specified variable
The Host may undefine all limits for all VIDs:
