8.3.2.48 FP_DATA
This command is used for data exchange with "functional profiles".
The content of the request and response bytes is depending of the called function
(see chapter 8.3.3).
8.3.3 Functional Profils
8.3.3.1 „Safety at Work“ List 1
Function: 00
16
List of "safety-directed input slaves" ("AS-i Safety at Work"), by which the dafety
function is released.
In this list are entered that slaves according to profile S-7.B or S-0.B, by which are
deleted all 4 bits in the IDI. Therefore slaves with 2 contacts are entered only then,
if both contacts are released.
Because the safety function of a safety-directed input slave can be released, if the
slave does exchange no data with the AS-i master, the list may be utilized only in
combination with the ec-flags.
