Analog modules
9.3 SM 336; F-AI 6 x 0/4 ... 20 mA HART
Fail-safe signal modules
Installation and Operating Manual, 01/2010, A5E00085586-10

WARNING
To achieve SIL3/Cat.4/PLe using this wiring, you must use a suitably qualified sensor.
Note
If you are using
SIMATIC PDM
as the engineering tool for your HART field device, create a
HART field device only for the channel with the lower channel number.

Discrepancy analysis for fail-safe analog input modules
For safety-oriented applications according to SIL 3, perform a discrepancy analysis with
2oo3 evaluation in your safety program (e.g. in
S7 F/FH Systems
with the F_2oo3_AI F-
block).
