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
depends on the device version.
PV = Primary Variable; SV = Secondary Variable; TV = Tertiary Variable; QV = Quarternary

Signal converter version
Basic I/O, connection terminals
Modular I/O and Ex i I/O, connection terminals
Table 9-2: Connection of the terminals to the HART
The signal converter can provide up to 14 measurement-related values. These values are
accessible as so-called HART
variables. The availability of these variables depends on the device versions and the settings.
