3. With the Object Address List, define the discrete or block transfer
PLC addresses for each object on your screen.
4. Enter the object reference number and screen number on the I/O
Usage Worksheets to map your PLC memory usage. Use the Discrete
I/O Usage Worksheet for discrete addresses. Use both the Discrete
I/O Usage Worksheet and the Block Transfer I/O Usage Worksheet
for Block Transfer Files. Use the Discrete worksheet to record any
block transfer control bytes in both the Input and Output sections of
the image table.
5. Use a new Screen Worksheet and Object Address List for each
screen. Use one Discrete I/O Usage Worksheet for each full or partial
rack assignment, and two Block Transfer I/O Usage Worksheets for
each block transfer file.
6. Use a separate Object Address List to record the addresses for your
windows and PLC controlled options, and map these addresses onto
the I/O Usage Worksheets. You may also wish to record all the
messages associated with the Alarm and Information windows, and
the Local Message Display object.
7. Only after you’ve finished assigning addresses to your objects,
windows and PLC controlled options will you know exactly how
many racks to assign to your PanelView terminal. Enter this
information on the PLC Communications Worksheet.
8. Calculate the size of the application file: your PanelView memory
requirements can’t exceed the terminal’s capabilities. Refer to
Table 4.E and
Table 4.J .
