Function
Contains the starting bank number
of EM file memory (bank number of
the first formatted bank). All EM
banks from this starting bank to the
last bank in EM are formatted for
use as file memory.
To convert the EM Area for use as
file memory, first set the PLC
Setup's EM File Memory Function
setting to 1, set the PLC Setup's EM
File Memory Starting Bank setting (0
to 18), and then format the EM Area
from a Programming Device
The PLC Setup's EM file memory
settings won't agree with the actual
settings unless the EM Area is for-
matted after the PLC Setup's EM file
memory settings have been
changed. In that case, the actual
settings can be determined with this
word.

one of these instructions is exe-
cuted, the number of words to be
transferred is written to A346 and
A347.

mented.

and A347 contains the leftmost 4-
digits.
