The PanelView terminal can share the same rack number with other
fractional Remote I/O racks and PanelView terminals. However,
PanelView terminals cannot be assigned the same rack number and contain
the same module group as another I/O chassis. The same rack number can
be assigned to a PanelView terminal and to other PanelView terminals or
I/O racks only if each is configured as a unique fraction of that rack
number. For example, Rack #1 could be configured as shown in Table 4.B.

A PanelView terminal object, window or PLC controlled option can be
assigned either a discrete or block transfer control address.

IMPORTANT: The SLC-5/02 and some PLC controllers do not support
block transfer addressing. See individual PLC controller manuals for this
information.

You can have up to five bi-directional block transfers (numbered 1–5) for
each PanelView terminal. A sixth block transfer file is reserved for the
pass-through function (the transfer of files between PanelView and the
computer over the Data Highway + connection). The Pass-Through block
cannot be used for normal block transfers. Refer to Chapter 6, File
Operations, for more information on the Pass-Through feature.

You must determine which byte—also known as module group and
slot—(in the I/O image table), will support each block transfer, and set up
the PLC’s block transfer instructions accordingly.
