6-2-8 EM Area
This area is used in word units (EM 0000 to EM 2047). The EM Area is contained
in I/O memory (i.e., memory that can be freely read and written to from the ladder
program). It is possible to specify whether or not EM Area settings are cleared at
power interruptions. This setting is made in bits 12 to 15 of DM 6600 in the Unit
Setup Area as shown below.
