SIMATIC PCS 7 OSx 4.1.2 Operator
The major hardware components of an OSx station are described below.
Monitor OSx uses a color monitor to display process graphics.
Keyboards OSx has two keyboards: a factory-hardened membrane
keyboard for the operator and a standard keyboard for the design engineer.
The engineering keyboard plugs into the operator keyboard for
configuration modifications in the Offline and Operate state. A rocker
switch on the back of the operator keyboard allows you to set the current
operational keyboard.
The operator keyboard is a sealed membrane keyboard and has been
optimized for use during process monitoring and control. Operations, such
as alarm management and screen navigation, are easier to do using the
operator keyboard. The engineering keyboard is a standard office-style
keyboard that is more convenient to use for system configuration.
Pointing Devices The operator can use either a mouse or a trackball for
cursor control.
Storage Devices Three data storage units are included: a 3.5-inch
diskette drive, a hard disk drive system, and a magneto-optical drive
system.
