CJ2 CPU Unit Software User’s Manual
Use the following file names. The files listed as being required in the right column must be on the Mem-
ory Card to perform automatic transfer at startup.
Additional Information
Setup data for the Special I/O Units and CPU Bus Units can be read from the Memory Card at
startup by storing data from the allocated DM Area words for Special I/O Units (D20000 to
D29599) and allocated DM Area words for CPU Bus Units (D30000 to D31599) on the Memory
Card as an AUTOEXEC.IOM file. Using Memory Cards in this way enables managing a library of
system data for Special I/O Units and CPU Bus Units for each piece of equipment.
