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 Areas 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.
