9.4 Inputs/outputs and HART ® dynamic variables and device variables
The signal converter is available with various in-/output combinations.
The connection of the terminals A…D to the HART ® dynamic variables PV, SV, TV and 4V depends
on the device version.
PV = Primary Variable; SV = Secondary Variable; TV = Third Variable; 4V = Fourth Variable
The signal converter can provide up to 10 measured values. The measured values are accessible
as so-called HART
® device variables and can be connected to the HART ® dynamic variables. The
availability of these variables depends on the device versions and the settings.
