8 - Input File List (PLCĆ2
Compatibility Mode Only)
Select the
Input File List
option from the configuration screen for a list
of files that the scanner accesses when receiving data using PLC-2 logical
data addressing (see chapter 5). When a PLC-2 command comes in from a
station on a DH or DH+ link, the scanner accesses the input file associated
with that remote station number. You must make sure the input file is
created in memory.
If you do not list an input file for a remote station, the scanner assigns a
default file to it. The default file number matches the remote station
number (except for remote station zero which is assigned input file 8):

Station address 000 is assigned to input file I008. Otherwise PLC-3 input
files with an 8 or 9 in their addresses are not used for read/write access by
a PLC-2 station.
If you do not want to use the default input file, you can use the input file
list selection. Upon selecting input file list, the list of remote station
addresses and associated input files displays. Initially, the list is empty and
default assignments do not display unless you enter them.
Important: You can assign a remote station to only one input file, but you
can assign different remote stations to the same input file.
