4.4 Parameters of HART Analog Modules
Overview of the
parameters
I/O Modules with Intrinsically-Safe Signals
C79000-G7076-C152-04
Table 4-4 lists the parameters for the HART analog input module, Table 4-5
lists the parameters for the HART analog output module. The tables show
which parameters can be set for the module as a whole and which parameters
can be set separately for each channel. General information on assigning
parameters can be found in the description of the SIMATIC-Ex analog
modules in Chapter 3.6.3.
