2-2 SIMATIC VPU200/560 Programming Manual
2.1 Loading the Operating System (O.S.)
To load the O.S., power up the VPU200 by pressing the rocker switch
(located on the front of the VPU) to the ON position (See Figure 2-1.) Next,
press the spacebar to display the Power -up Menu. This menu contains the
options for loading O.S., copying and formatting disks, and running
diagnostics on the VPU. Before loading the O.S., run diagnostics and copy or
format any disks as needed. Once the O.S. is loaded, this menu may be
accessed for these functions by either power cycling the VPU or exiting to
the first menu after loading the O.S. and using the F1 key .
Figure 2-1 VPU200

Start-Up 2-3 SIMATIC VPU200/565 Programming Manual
Insert the O.S. disk into the disk drive and depress the load switch until it
is flush with the front of the disk drive. Press F2 to initiate the load
operation. Once the O.S. disk is loaded, the selection shown in Figure 2-2
appears at the bottom of the screen.

2.2 Selecting Operating Mode
The function keys available on the initial display are labeled as follows:
The F1 key provides access to the Power -Up menu for copying and
formatting disks or running VPU diagnostics.
The operating modes are ONLINE and OFFLINE. In online mode, the VPU
and the programmable controller (P/C) communicate; and any changes
entered on the VPU can be written directly to the P/C and to the disk in
some instances. In Offline mode, there is no communication between the
VPU and P/C; and programs edits, etc., must be written to disk to save.
Function keys F4 and F5 provide the options of accessing support functions
or printing cross-references. If F4, Support, is selected, the VPU performs
this operation in Online mode. (See Section 7.) W ith the selection of F5,
printing of cross-references is done in the Offline mode. (See Section 8.)
After you make a selection from the menu, the operating system is loaded
for that function. As the O.S. is loaded, a message and a series of dots
appear on the screen. The message tells you what operating system is being
loaded; i.e., OFFLINE, ONLINE, etc.
NOTE: After selecting either offline or online mode, configure S-memory .
Until S-memory is allocated, the 565 functions are not accessible from the
VPU200.

Start-Up 2-5 SIMATIC VPU200/565 Programming Manual
The screen of the VPU200, Figure 2-3, has areas reserved for display of
specific types of messages:
• The Function Key numbers and labels which describe the operation
available with the keys on that particular menu appear on the last line
of the screen.
• System messages and prompts are given on the left side of the screen
on the second and third lines from the bottom.
• Operating status is shown in three fields on the right side of the screen.
In the first field, either REMOTE or LOCAL will be displayed to show
the status of the Network Interface Module (NIM). If all NIM switches
are set to LOCAL or no NIM is being used, LOCAL is displayed. If any
NIM, is set to REMOTE mode, REMOTE is displayed. The second field
shows the type of P/C that is used, and the third field gives the mode of
the P/C– either PROGRAM or RUN.
Figure 2-3 Message Ar eas of the VPU200
The function key line appears at the bottom of each display . The function
identifiers, F1, F2, etc., show that the functions, EMT–F1, PRINT–F2,
LADDER–F3, etc., are selected by pressing the corresponding numbers of
the F keys on the VPU200 keyboard. If more than eight functions are
available from a particular menu, the + (spacebar) is displayed to the right
of the function key line. Press the spacebar to change the function key
display to the additional functions. Press the spacebar again to return to the
original display . The + (spacebar) does not appear if there is only one set of
functions at a particular level.

3.1 Available Functions
When the LOOP (F1) function key is pressed, the first page of the loop
directory will appear on the screen. This page contains the first 32 loops;
there is a second page containing the remaining 32 loops.
The directory shows the title of each loop, whether the loop is programmed,
and whether the Ramp/Soak feature has any programmed data. This
information is derived from the data entered when the loops and R/S steps
are programmed. Figure 3-1 shows an example of the first page of the loop
directory.
