Hysteresis +/- GA3
This entry allows you to add hysteresis to the equation:
Value ON if 1A4 > 2A5 Hysteresis +/- GA3
Default value: 25 20 5
In the above example, the value of 1A4 must be greater than 2A5
by the value of GA3 before the global will go ON. Also, the value
of 2A5 must be less than 1A4 by the value of GA3 before the global
binary will go OFF. If the analog value that is entered here (GA3
in the above example) is invalid or unavailable, the default value
under the analog value will be used as the amount of hysteresis.
In Local Set this global defaults to ____
Specifi es the state (or value) of the binary global when the satellite
is in the Local Set mode. The satellite is in local set when it has lost
communications with the front end computer.
---------------ALARM----------------
Set Condition: None Type: 0 Message 0
The system has the capability of generating an alarm if the
value of this binary global is either ON or OFF. The type is 1-8,
1 being the highest priority and 8 being the lowest. The system
will automatically print out the alarm message associated with
the message number above. The ECC/WCC II system can report
alarm types 1-5 to a remote printer.
