2.8.4 Message Routing
Information on various topics is provided by the system in the form of messages. Messages are divided
into categories called message classes. This enables the system to distinguish between different kinds of
messages and allows efficient message sorting.
Messages within each class are further distinguished by separation into message types. Definitions of
types within a Message Class enables the Micro-PWC to quickly process and sort messages within a
class.
Message Classes on the Micro-PWC include:
• Process Alarms
• System Events
• Operator Messages
• Device Failures
• Operating Status Messages
• Module Diagnostics
• Status Changes
• Operating Errors
• Operator Actions
Process Alarms, System Events, and Operator Messages provide information which must be immediately
available to the operator. Messages from these three classes are displayed in the Mini-Alarm Window on
the Micro-PWC screen. The remaining Message Classes reflect status changes in the system rather than
alarm conditions. Messages belonging to these classes are not displayed in the Mini-Alarm Window. Log-
ging of messages is configurable.
In addition to Message Classes, Message Routing also allows the filtering of messages based on the fol-
lowing parameters:
• Priority
• Area
Message Routing enables messages of any Message Class to be separately routed to any device which
has been configured through the Printer Assignment menu selection (see
Section 2.8.3, Printer Assign-
ment ). Message Routing also allows the selection of which Message Types in each Message Class are to
be routed to any device, filtering out messages which are not important for the specific application.
