Macros are software modules programmed from functions. Macros in a plant are
available in a single plant. It is up to the user to create, edit or remove such
macros. The same macro can be used many times in a plant. If a macro in a
plant is changed, the macro change will appear in all instances of the macro in
this plant, but not in other plants.
• System Macros
Honeywell provides system Macros. They are available for all projects of the
Database. These macros are protected against editing and removing.
• Library Macros
Library Macros are project independent macros created by the user. The same
macro can be used many times in a library. If a macro in a library is changed, the
macro change will appear in all instances of the macro in this library, but not in
other libraries.
Parameters are used for configuration and tuning of the application program via
control loops. A typical example of a parameter is the Integral Time of the PID
control function.
Parameters are part of a control icon which itself is part of a control loop which itself
is part of a plant, etc. Hence, the parameter can be described and addressed by its
path as follows:
plant – control loop – control macro - control icon – parameter
Example: airconditioning.contloop1.supply_temp.integral time
A parameter is defined by:
• Name
• Value
• Engineering unit/state text (in the Excel Web HTML interface only supported for
control macros, not for control functions)
The cycle time category defines the time in ms after a control loop is restarted
automatically. To view/set cycle time categories, please refer to the "View/Change
Cycle Time Categories" section.
System settings include the following settings:
• System date, time and time zone
• Cycle time category (see also "Cycle Time Category" section).
• Communication settings
Communication settings include:
• Interface settings for serial ports, Ethernet, LON, Modem and Web-Server, such
as baudrate, IP address, neuron chip ID, automatic logout time of web server
• User name and password definition
• Selection of the serial port for modem connection
• Selection of remote front-end
• Dial out parameter (re-dial algorithm) definition
