Manipulating Files Section 5-2
Note 1. When the backup operation is completed normally, power to the Memory
Card will go OFF when the MCPWR indicator goes OFF. If the Memory
Card will be used again, press the Memory Card Power Switch to supply
power and execute the desired operation.
2. When data is written for a simple backup operation from a CS1-H, CJ1-H,
or CJ1M CPU Unit, errors for insufficient Memory Card capacity can be
checked in A397 (Simple Backup Write Capacity). If A397 contains any
value except 0000 Hex after the write operation has been executed, the
value will indicate the capacity that is required in the Memory Card in
Kbytes.
3. With CS1-H, CJ1-H, or CJ1M CPU Units, the backup files for Units and
Boards are also compared.
Comparing data between the
CPU Unit and the Memory
Card
Lit → Remains lit while the
Memory Card Power Switch
is pressed. → Flashes once.
→ Lit while comparing. →
OFF after data is compared.
Lit → Remains lit while the
Memory Card Power Switch
is pressed. → Remains
flashing. → Lights when the
Memory Card Power Switch
is pressed.
The following comparison
errors can occur (See note
3.):
Memory Card and CPU Unit
data do not match.
Required backup files do not
exist in Memory Card.
EM files and CPU Unit EM
banks do not match (non-
consecutive bank numbers
or max. bank number mis-
match).
Memory error in CPU Unit
I/O bus error (when compar-
ing data to a Unit or Board,
CS1-H or CJ1-H CPU Units
only)
Common to all three backup
operations.
