Backup and Recovery

4-8-2 Recovery Procedure

1, 2, 3...
• If the stop command is executed during backup processing, operation will stop
but backup processing will continue.
• If backup is attempted before processing for a previous backup operation is
started, the latter backup operation will be invalidated. Perform backup again
once backup processing has been completed.
• The following operations are not possible during backup processing. "Now
executing back up operation. Stop processing" will be displayed if an attempt is
made.
1. Main Screen (Including Pop-up Menus)
• Settings – Program Protection – Edit LCB Password
• Execute – Delete Registration Function Block – Delete
• Execute – Transfer to LC – FBD Information
• "Reset the load rate" under Execute – Operation – Monitor Run Status
(Set the ITEM displayed as "Reset" to 0.)
• Execute – Operation – RUN/Stop Command – HOT START (or COLD
START) (Here, an error code of 110C will be generated.)
2. User Link Table Pop-up Menu
• Transfer to LC – Selected Entries
• Transfer to LC – All Entries
3. Edit Block Diagram Mode Menus (Including Pop-up Menus)
• Manipulate FBD – Setting Block Operation Cycle – Transfer to LC
4. Downloading the System Common Block when transferring individual ITEM
data settings
5. Transferring LCU/LCB folder or function block groups
6. Executing the Clear All operation
7. Executing the Recovery operation
Note If the power supply is interrupted while backup is being performed during opera-
tion, backup processing will be automatically re-attempted after the power sup-
ply is restored. In this case, backup will be performed with the Loop Controller
operation in the stopped state. (With the CS1D-CPUjjP, CPU Unit operation
will also stop.)
1. Select an LCU/LCB element.
2. Select Backup Data Operation – Recovery from the Execute Menu.
Note For a Loop Control Unit, the contents of flash memory will be automatically trans-
ferred to RAM at startup if pin 2 of the DIP switch on the front of the Loop Control
Unit is turned ON. (This function is used to enable battery-free operation.) The
basic procedure is as follows:
a) Execute Backup Data Operation – Backup from the Execute Menu.
b) Turn OFF the power supply to the PLC.
c) Turn ON pin 2 of the DIP switch on the front of the Loop Control Unit.
d) Turn ON the power supply to the PLC.
For an LCBjj, the contents of flash memory will be automatically transferred
to RAM at the following times.
• When a cold start operation command is given
• When a RAM error (data lost) occurs when power is turned ON, causing a
cold start
• When ITEM 101 (backup start command) in the System Common block is
ON and a flash memory error occurs but RAM is normal when power is
turned ON (RAM data will automatically be backed up to the flash memory
first and then a cold start will be implemented automatically.)
