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".

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.
