Running OPC90 as a service along with the “Start In Runtime” and “Monitor”
option is ideal for automatic system startup after a PC reboot and continuous
runtime mode even after all clients detach from the server. On startup, OPC90
will establish its database with the Bailey system prior to any clients attaching to
it reducing the time it takes to gain initial access to database points. After a client
attaches and detaches, runtime will not be stopped when monitor is still enabled.
Note that it is not absolutely necessary to run OPC90 as a service since OPC by
definition automatically starts the server when any client makes a request for its
data. Therefore, if problems are encountered with clients attaching to OPC90
running as a service that cannot be resolved by also running the client as a
service, or within the same account the OPC90 service is running, then running
as a service should be disabled.
5.5 Utilities
The utilities menu option can be used to easily run the Windows service manager
or DCOMCNFG program. It can also be used to view OPC90 device and error
detection log files. The following picture shows these available View menu items:
5.5.1 Service
Manager
Selecting the Utilities | Service Manager menu option results in the Windows
Service Manager to run. That program allows the OPC90Server service
properties to be modified and the service started. The service manager is
automatically run by OPC90 when it has been requested to set itself up as a
service (see View | Run as Service).
5.5.2 DCOM
Configuration
Selecting the Utilities | DCOM Configuration menu option results in the Windows
DCOMCNFG program to run. That program allows DCOM to be setup for the
computer and OPC90.
5.5.3 View My Logs
Selecting the Utilities | View My Logs menu option displays a file open dialog
allowing a specific OPC90 device or error log file to be selected and viewed by
opening it in notepad.
5.6 Block
Faceplates
Block faceplates are a handy engineering feature that allows real time monitoring
and control of any block in the database. These faceplates are available
