• Annual programs
• The "TODAY" function
• Special day list
Daily programs are used to create a weekly program. The annual program is
created automatically by multiplying the weekly program and then incorporating
additional daily programs. The "TODAY" function enables you to have a direct
influence on the switching program. This function enables you to allocate a setpoint
or status to the selected datapoints for a defined time period. This action does not
depend on the current daily program.
Alarm handling The alarm handling facility offers system security. Alarm signals can, for example,
alert the operator to maintenance work that is due. All alarms that occur are stored
in data files and reported immediately. If your system configuration allows, you can
also list alarms on a printer or transmit alarms to higher-level front-ends. There are
two kinds of alarm: Critical and Non-critical. Critical alarms have priority over non-
critical alarms. System alarms, caused by a fault in a controller, are always critical
alarms.
To distinguish between alarm types, you can generate your own alarm messages or
select appropriate messages already in the system.
The following events all generate alarm messages:
• Exceeding limit values
• Overdue maintenance work
• Totalizer readings
• Digital datapoint changes of state
Application program You can use the Honeywell CARE engineering tool to create application programs
for your system. A particular advantage offered by Honeywell CARE is the ability to
create a fully functional control program without having to be familiar with the
programming language. CARE stands for Computer Aided Regulation Engineering.
Passwords Your control system is also protected by passwords. This ensures that only
authorized persons have access to the system data. There are four operator levels,
each protected by its own password.
• Operator level 1: Read only; the operator can display information about
setpoints, switching points, and operating hours.
• Operator level 2: Read and make limited changes; the operator can
display system information and modify certain preset
values.
• Operator level 3: Read and make changes; system information can be
displayed and modified.
• Operator level 4: Programming.
Password protection prevents unauthorized access system information and ensures
permanent, secure system operation.
