This table lists the Variables for which the Host may set limits and the event which is
called in case of a Limits Monitoring transition.
VID Variable Min Max Event
(YHQW6LJQDOLQJ
For any event that exists on the Equipment, the event message will be sent to the Host
only if the reporting for that particular event has been enabled. In this "EVENT
SIGNALLING" section, assume that the Host has enabled the proper reporting so that
these events will be sent to the Host.
After the Host sets UPPERDB and LOWERDB values for a particular limit, the SIPLACE
will send an event message when a transition occurs across these boundaries. The
procedure for reporting is explained in the following chart and state chart diagram:

# 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.

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 LOWERDB.
Above Limit
The value of the variable is greater than or equal to UPPERDB.

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.
