5.2.14 Host Reads Equipment
Step SECS Message Description
1. H -> E S2F13 W Host requests the values of one or more
Equipment Constants.
2. H <- E S2F14 The Equipment responds with the values of the
requested Equipment Constants.
5.2.15 Host Sets Equipment Constants
Step SECS Message Description
1. H -> E S2F15 W Host sends new values for one or more
Equipment Constants.
2. H <- E S2F16 If all new values are valid, the Equipment saves
the new values and sends this message with an
acknowledge code of „0“. If one or more new
values are not valid, no Equipment Constants
are changed and the acknowledge code in this
message is non-zero.

5.3 Alarms
5.3.1 Equipment Reports Alarm
Step SECS Message Description
1. H <- E S5F1 [W] If reporting for this alarm ID is disabled, skip this
and the following step. Otherwise send the
alarm. The Equipment Constant {XE
„WBitS5“}WBitS5 determines whether the W-bit
is 0 or 1 in this message.
2. H -> E S5F2 If the W-bit in S5F1 is 1, the Host acknowledges
the alarm report. Otherwise, skip this step.
3. H <- E S6F11 W If the event ID associated with this alarm state is
enabled, send the event report. Otherwise, the
scenario ends.
4. H -> E S6F12 The Host acknowledges the event report.
5.3.2 Host Enables/Disables Alarms
Step SECS Message Description
1. H -> E S5F3 [W]
The Host specifies {XE „ALID“}ALIDs to be
enabled or disabled.
2. H <- E S5F4 If the W-bit in S5F3 is 1, the Equipment
acknowledges.
5.3.3 Host Requests Alarms
Step SECS Message Description
1. H -> E S5F5 W
The Host requests whether specified {XE
„ALID“}ALIDs are „on“ or „off“.
2. H <- E S5F6 The Equipment sends Alarm status.

5.3.4 Alarm Report (GEM, Ver 3.1 Compatibility)
Note: This scenario is provided only for compatibility with Host computers which support
GEM, Ver 3.1.
Step SECS Message Description
1.
The Equipment Constant {XE
„ConfigAlarms“}ConfigAlarms is set to 2 for non-
GEM compatibility.
The Equipment recognizes that an alarm
condition has gone „on“ (i.e. has become
Unsafe).
2. H <- E S5F73 [W] The Equipment reports the Alarm going on. The
high-order bit of {XE „ALCD“}ALCD is „1“.
3. H -> E S5F74 If the W-bit of S5F74 is 1, the Host
acknowledges the Alarm.
4. The Equipment recognizes that the alarm
condition has gone „off“ (i.e. has become Safe).
5. H <- E S5F73 [W] The Equipment reports the Alarm going off.
The high-order bit of ALCD is „0“.
6. H -> E S5F74 If the W-bit in S5F74 is 1, the host
acknowledges the Alarm.
5.3.5 Alarm Report (GEM, Ver 1.7 Compatibility)
Note: This scenario is provided only for compatibility with Host computers which support
GEM, Ver 1.7.
Step SECS Message Description
1. The Equipment Constant ConfigAlarms is set to
1 for GEM, Ver 1.7 compatibility.
The Equipment recognizes that an alarm
condition has gone „on“ (i.e. has become
Unsafe).
2. H <- E S5F71 [W] The Equipment reports the Alarm going on. The
high-order bit of {XE „ALCD“}ALCD is „1“.
3. H -> E S5F72 If the W-bit in S5F71 is 1, the Host
acknowledges the Alarm.
4. The Equipment recognizes that the alarm
condition has gone „off“ (i.e. has become Safe).
5. H <- E S5F71 [W] The Equipment reports the Alarm going off.
The high-order bit of ALCD is „0“.
6. H -> E S5F72 If the W-bit in S5F71 is 1, the Host
acknowledges the Alarm.
