The following SIMATIC S7 HART analog modules are described in this
chapter:
SM 331; AI 2 x 0/4...20mA HART (HART analog input module)
Order number: 6ES7 331-7TB00-0AB0
SM 332; AO 2 x 0/4...20mA HART (HART analog output module),
Order number: 6ES7 332-5TB00-0AB0
This chapter provides you with the information you require in order to use
the module as a HART interface:
An introduction to HART, to help you familiarize yourself with the
technology,
Guidelines for installation, startup, and operation, with the aid of a
sample configuration,
HART-specific parameter assignment and diagnostics,
Technical data for the HART analog modules.

The SIMATIC S7 HART analog modules belong to the category of SIMATIC
S7-Ex analog modules. Their basic properties were described in Chapter 3
and also apply here. The channel properties of the HART analog input
module correspond to the properties of the module SM 331;
AI 4 x 0/4...20mA. The channel properties of the HART analog output module
correspond to the properties of the module SM 332; AO 4 x 0/4...20mA.
The HART analog module can only be used within the ET200 M distributed
I/O system with the interface module IM153-2AA01, IM153-2AB00 or
IM153-2AB80 acting as a connection to the PROFIBUS DP.
