4.7 Functional Profiles
4.7.1 "Safety at Work" List 1
4.7.1.1 Slave list with EcFlags
(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 4.5.4 Read actual configuration (READ_CDI), page 45: 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 4.4.3 Get Flags (GET_FLAGS),
page 33: "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 safety monitor is also being activated when a safety 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.
4 prm byte (index+1)
n+2 prm byte (index+n-1)
This function has been implemented only for reasons of the downwards com-
patibility.
By AS-i 3.0 Masters, the state of the "safety input slaves" is specified on the
image of the input data (0000 released).
