device variables
The HART® dynamic variables PV (Primary Variable), SV (Secondary Variable), TV (Third Variable)
and 4V (Fourth Variable) can be assigned to any of the device variables.
The HART
®
dynamic variable PV is always connected to the HART
®
current output which is, for
example, assigned to level measurement.
