3.5. Starting SYS 600
3.5.1. Starting base systems
To start a base system:
1. Switch on the computer and the display.
2. After the power has been switched on, the memory is tested and the operating
system is started.
3. MicroSCADA can be started either manually or automatically, depending on the
configurations made to the system.
4. You can log on to Windows, either automatically or manually, depending on the
configurations you have made to the system. Manual logging is needed only if
monitors are opened manually in the same computer where base system is
running.
3.5.2. Base System startup procedures
Base system runs as a service in the operating system. This means that the program
runs in the background without any visible user interface.
At startup, the MicroSCADA main program runs the following operations:
*
The base system is configured with the SYS_BASCON.COM file.
*
The remote communication system is configured and possible NET units are
started (SYS_NETCON.COM).
3.5.3. Application startup procedures
The applications that are configured in the SYS_BASCON.COM are started after
the service has started. For each application that has started and has been set to
"HOT", the following tasks are performed:
*
The entire process database of the application is copied from disk to the primary
memory. The values for process objects with SS= =2 are marked as not logged
(status code 10).
*
An event channel (APL_INIT_1) is activated. Often the channel starts an
application-specific command procedure(s). The function is defined in the event
channel configurations.
*
All time channels in the active applications, which are connected to data objects
and should have started during the system break, are executed. The missing
report data, due to the break, is marked as not logged. Command procedures and
data objects with SE= =1 are executed. After the marking of data objects is
complete, another event channel (APL_INIT_2) starts another command
procedure(s).
The tasks are performed regardless of whether they are started from the
SYS_BASCON.COM file or later on. If the application is a part of a hot stand-by
system, the procedures are identical.
