Each command list record has the same general format. The first part of the
record contains the information relating to the communication module and the
second part contains information required to interface to the DF1 slave device.
The PLC-5 and SLC-500 command set require the use of files. These files are
emulated in the module. The module defines these files each as containing 200-
word registers that overlay the internal database. The following table shows the
relationship of the files to the user data area of the internal database.
