PROGRAM STATE C04
The purpose of this panel is to allow the user to inspect the status and settings
of a particular program. The program number indexes this panel. This panel
contains the following information:
− Program Number Program Number Program Number Program Number Program Number – The current selected program. Act as index for the
panel (used to view settings for all programs).
NOTE: This is the only panel where the current program can be changed.
− Program State Program State Program State Program State Program State - During the lifetime of a program it cycles through several
states. Each program is initially in NO SET state which means no settings
have been applied to the program by the user. Once the settings have
been applied the program is considered in SET state. Once a specific
condition such as start time is met the program passes to READY state to
await execution. Once the program reaches the highest priority and the
start time is met, the program passes to ACTIVE state and executes. The
program may be suspended and placed in WAIT state due to a higher
priority program moving to ACTIVE state or a specific alarm condition
triggering. When a program completes execution it is placed in FIN-
ISHED state. The cycle may be repeated and the program returned to
ready state if the program repeats were specified after a set delay period.
− Program Started by Program Started by Program Started by Program Started by Program Started by - Displays how the last program start was triggered.
Programs can be started by a met time condition, manual start, low level
in external tank, or directly after the completion of another program. If the
program is in NO SET (no settings applied to program) or in SET (settings
applied but conditions not met) state, .Started by field is blank.
− Repeat Repeat Repeat Repeat Repeat - Displays the current repetition followed by (/) the maximum num-
ber of the programmed repetitions.
