8.2.3 Functional profiles
8.2.3.1 "Safety at Work" List 1
Function: 00
16
List of "safety-directed input slaves" ("AS-i Safety at Work"), whose safety function
is released.
Safety-directed input slaves have the profile S-7.B or S-0.B (IO = 0 or 7, ID = B,
see chapter 8.2.4.4: Read Actual Configuration).
The "Safety at Work" list 1 is a bit list which contains a bit for each possible slave
address (1
- 31). This list is written in the bytes 5 until 8 in the response of the com-
mand of the command interface. Additionally, the reponse contains the ec-flags
of the AS-i master in the bytes 3 and 4 (
see chapter 8.2.2.2: "Get Flags").
The bits of the "Safety at Work" list 1 are set if the safety function of the slave is
activated (e.g. emergency button pressed). The bit is only set at security slaves
when both contacts are released, otherwise the bits have the value 0. "Normal"
(non-security) slaves also have the value 0.
Since the security monitor is also being activated if a security slave is missing or if
the AS-i circuit is shut off (offline active), the ec-flags will also be transmitted. It is
sufficient however to monitor the group error message Cok (configuration error).
As long as no configuration error, the list of the "safety-directed input slaves" can
be used.
Configured safety slaves which are not available, and available slaves sending a
wrong coder order, will not be entered in this list.
With the bit "O", the sequence of the bits within the "Safety at Work" list 1 can be
chosen.
