LIMITS STATE TRANSITIONS
# From Trigger To Description
1 Enabled Host undefines limits
attributes.
Disabled Host sends S2F45 to
undefine limits.
2 Disabled Host defines limits. Conditional Host sends S2F45 to
define limits.
3 Below Limit Variable changes to
greater than or equal to
UPPERDB.
Above Limit Limit transition event is
signaled to Host if
enabled.
4 Above Limit Variable changes to less
than or equal to
LOWERDB.
Below Limit Limit transition event is
signaled to Host if
enabled.
5 No Zone Variable changes to less
than or equal to
LOWERDB from No
Zone.
Below Limit Limit transition event is
signaled to Host if
enabled.
6 No Zone Variable changes to
greater than or equal to
UPPERDB from No
Zone.
Above Limit Limit transition event is
signaled to Host if
enabled.
Limits States
A Variable's defined limits may be in any of the following states.
Disabled
Limits are not defined.
Enabled
Within this super-state, a limit has been defined, and monitoring of the variable
is taking place.
No Zone
This limit has just been defined, and the value of the variable is less than
UPPERDB and greater than LOWERDB. No limits transitions have occurred.
Below Limit
The value of the variable is less than or equal to {XE
"LOWERDB"}LOWERDB.
Above Limit
The value of the variable is greater than or equal to {XE
"UPPERDB"}UPPERDB.
3.4.8 Disk Files{XE "Disk Files"}
The SIPLACE maintains a disk file which contains the current Equipment Constant
settings. The file is updated each time the Operator or Host changes an Equipment
Constant. The most recent settings for some of the Equipment Constants are read from
the file when the Equipment is powered-on.
All Event Report definitions, links, and enable status as well as Limits attributes are also
maintained on separate disk files.

Compatibility
The SIPLACE supports the following Event Report message formats for non-GEM Host
implementations.
{XE "S6F3"}S6F3/{XE "S6F4"}S6F4
{XE "S6F9"}S6F9/{XE "S6F10"}S6F10
{XE "S6F13"}S6F13/{XE "S6F14"}S6F14
3.4.9 Related Variables
The following table lists the variables (SV's, EC's, or DVVALS) which are relevant to data
collection setup and maintenance. This section does not list the variables which contain
equipment-specific information. For a more complete description of specific variables,
see "Appendix A -- Variables".
Variable Name VID
{XE
„GEMLIMITSTIMER“}GEMLIMITSTIMER
1002050
{XE „GEMLIMITSVID“}GEMLIMITSVID
1002047
{XE „GEMEVENTLIMIT“}GEMEVENTLIMIT
1002048
{XE „GEMTRANSTYPE“}GEMTRANSTYPE
1002049
{XE „ECIDCHANGE“}ECIDCHANGE
1002036
3.4.10 Related Events
The following lists the collection events (CEIDs) which are relevant to data collection. In
addition to these, each variable which is eligible for limits monitoring must have a
specific collection event associated with it. For a more complete description of these
events, see "Appendix B -- Collection Events" or the description in this chapter.

3.5 Alarm Management
The SIPLACE has a fixed set of alarm conditions which can occur. Each alarm is
identified by a unique Alarm ID (ALID), and has an associated severity code (ALCD) and
alarm text (ALTX). The possible alarms are shown in "Appendix C -- Alarms".
3.5.1 Alarm States{XE "Alarm States"}
Each alarm (ALID) can be in either of two states: CLEAR (off) or SET (on). Several
alarms can be SET simultaneously. At power up, all Alarms are cleared.
3.5.2 Reporting
The SIPLACE reports alarms to the Host when they occur, without Host action, using the
alarm report message {XE "S5F73"}S5F1 or configurable option, depending on {XE
"CONFIGALARMS "}CONFIGALARMS (VID 1002018). The transition of an ALID from
OFF to ON is referred to as "going on" or "leading edge", and the transition from ON to
OFF as "going off" or "trailing edge". The Equipment reports both leading and trailing
edge transitions.
The equipment has two CEIDs for each ALID, one for the "going on" transition and one
for the "going off" transition. In addition to the Alarm Report, the Equipment sends an
Event Report if the CEID associated with the alarm change is enabled. If the CEID is
enabled and no report is defined, a "null" Event Report is sent. The event report for an
alarm transition is sent if it is enabled, even if the reporting for the alarm is disabled.
3.5.3 Enable/Disable
The Host can use {XE "S5F3 "}S5F3 ({XE "Enable/Disable Alarms"}Enable/Disable
Alarms) to control which alarms the SIPLACE should report. Using S5F3, the Host can
specify for each ALID whether the Equipment should report that alarm when it occurs.
When an alarm transition occurs, if that ALID is enabled the Equipment will send an
alarm report message to the Host. If the ALID is disabled, the Equipment will not send
the alarm message. The Host can use {XE "S2F37 "}S2F37 to enable or disable the
CEIDs associated with these alarm transitions.
The SIPLACE saves Alarm Enable/Disable settings on a disk file. When the Equipment
powers up, it will restore Alarm Enable/Disable settings to the same condition they had at
power off.
3.5.4 Host Requests Alarm Status
The Host can use {XE "S5F5 "}S5F5 to request the SIPLACE to report all alarms which
exist and the ON/OFF state for each.
The Host can use {XE "S5F7 "}S5F7 which is similar, but which causes the Equipment to
report only those alarms (ALIDs) which are Enabled, regardless of whether the alarm is
ON or OFF.
3.5.5 Compatibility
The SIPLACE supports the following Alarm Report message formats for older host
implementations.
{XE "S5F71"}S5F71/{XE "S5F27"}S5F72
{XE "S5F73"}S5F73/{XE "S5F74"}S5F74
