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, errors for insufficient
Memory Card capacity can be checked in A397 (Simple Backup Write Ca-
pacity). If A397 contains any value except 0000 Hex after the write opera-
tion has been executed, the value will indicate the capacity that is required
in the Memory Card in Kbytes.
3. The backup files for Units and Boards are also compared.
Note The CS1G/H-CPU@@(-V1) and CJ1@-CPU@@ CPU Units do not
support the Unit/Board backup function.
