Outline Section 1-1
Note 1. Function block data in RAM can be backed up to flash memory using either
of the following methods.
a. When downloading LCB01, LCB05, or LCB05D function block data
(i.e., by LCBs), specify LCB backup for the download (i.e., by placing
a check mark by “LCB back up indication after download”).
b. Specify backup from the CX-Process Tool software using the Execute
- Backup menu command.
2. Recovering data from flash memory to RAM is also possible using either
of the following methods.
a. Set the power ON startup mode to Cold Start and turn ON the power
supply to the CPU Unit.
b. Specify recovery from the CX-Process Tool software using the Exe-
cute - Recovery menu command.
3. Specify backup using ITEM 125 (Backup start command while running) of
the System Common Block (Block Model 000).
During operation of the Loop Controller, the backup will start when
ITEM 125 (Backup start command while running) of the System Common
Block (Block Model 000) is turned ON.
4. If duplex operation is used with the CS1D-CPU@@P and data in LCB Units
is downloaded during operation, operation data will be backed up in the
flash memory of only the active Board. The Loop Controller will stop oper-
ating at this time. If the power supply is turned OFF before starting opera-
tion with either a hot or cold start, the data will exist only in the flash
memory of the active Board, so a duplex verification error will occur. If this
occurs, check the RDY indicator on the standby Loop Controller in the CPU
Unit to make sure that it is ready to operate and then press the initialization
switch on the Duplex Unit to initialize duplex operation.
