SM 335 – High-Speed Analog Input/Output Module for the SIMATIC S7-300
6ES7 335-7HG00-8BA1
3.2.2 SM 335 parameters assignable with HW Config
Parameter assignment application
The STEP 7 tool used to initialize the analog modules in a STEP 7 environment is
called “HW Config”.
SM 335 parameters
Table 3-9 provides an overview of the SM 335 parameters which can be assigned
with HW Config.

*)
1 to 16 ms 0.5 ms
*)
Diagnostics for outputs (short-circuit test) yes/no no
Response with CPU-STOP “Keep last value
(KLV)” or
“Output have no cur-
rent or voltage
(OCV)”
“Output have no
current or voltage
(OCV)”

The setting 0.5 ms in HW Config means: Free Cycle
The setting of 1 to 16 ms in HW Config means: Conditional Cycle
