instructions, or Auxiliary Area control bit operations. The file names can be
defined by the user.

This file is automatically transferred from the Memory Card to the CPU Unit
when the power is turned ON. There are two ways to transfer files automati-
cally at startup: transferring with a parameter file and transferring without a
parameter file.
Type of automatic
transfer
Transfer with parameter file AUTOEXEC or
Transfer without parame-
ter file (See note.)
Note Supported by CS/CJ-series CPU Units with unit version 2.0 or later.
The File column indicates the files that must be present in the Memory Card
to enable automatic transfer at startup.
