Input parameters
RD_HW-ID
HW_SUBMODULE
-
Decisive hardware identifier for reading
data from a DP standard slave /PROFINET
IO device.
When selecting the frame type in the
properties of the SINAMICS drive in the
TIA Portal, STEP 7 creates a system
constant which corresponds to this
identifier. Enter this system constant here.
It is symbolically displayed to you in the
dropdown list when entering the
parameters.
WR_HW-ID
HW_SUBMODULE
-
Decisive hardware identifier for writing data
to a DP standard slave /PROFINET IO
device.
When selecting the frame type in the
properties of the SINAMICS drive in the
TIA Portal, STEP 7 creates a system
constant which corresponds to this
identifier. Enter this system constant here.
