OSx Station Basics 1-23SIMATIC PCS 7 OSx 4.1.2 Operator
1.5 Basic System Functions
To power up an OSx station, follow these steps.
1. Turn on the monitor.
2. Turn on any external devices, such as MO drive and printers.
3. Turn on the system unit. After a few moments, the system completes
the boot sequence and displays the main screen.
NOTE: Whenever the operator powers up or changes states, it is necessary
to wait for the system to transition completely to the requested state before
interacting with the system using the keyboard or mouse. Attempting to
type while a state change is in process could result in the system either
going to the Failed state or continually trying to go to the Failed state. The
only way to recover at this point is to shut down the system and reboot.
NOTE: When the operator shuts down the system and reboots with a floppy
disk in the disk drive that is not a boot disk, the only indication of this is a
flashing cursor. The system does not proceed through the boot procedure
and no error message appears. To reboot properly, the operator must remove
thefloppydiskandturnthepowerswitchoffandthenonagain.
The operator must log on before working with the process operation. To log
on the system, the operator selects
Controls-->Logon on the menu bar and
enters the appropriate User ID and password (Figure 1-4).
