Description of Operation
Note:
Applications
Procedure
Backing up function block
data files to a Memory
Card
(1) Function block ITEM data is the data that is not initialized for a cold start.
(i.e., ITEM data with an n-dash (−) in the COLD start initialization column
for the function block reference ITEM). This is the data that is backed up,
restored, or compared using a Memory Card.
With LCB01/03/05 Ver. 3.0 or later, block diagram information, tags, com-
ments, and annotations are backed up for the easy backup function. This data
was not backed up for earlier versions. Also, the data that is backed up has
changed from the data in RAM to the data in flash memory. This prevents ver-
ification errors from occurring during the easy backup operation when function
block parameter ITEMs have been changed in RAM data for Loop Controller
program operations. (A verification error will occur with earlier versions.)
The Loop Controller RAM data described above is backed up on Memory
Card as a Unit/Board backup file with the following file name whenever the
easy backup is used to write data to the Memory Card.
File name: BACKUPE1.PRM
(2) E1 is the Loop Controller's unit number = E1 hex.
Data in this file can be restored and compared from Memory Card. The Loop
Controller backup file is called a function block data file in the following
description, though it also contains tag and comment data.

Note Do not perform an easy backup operation from the CX-Process Tool while
backing up function block data from RAM to flash memory or while transfer-
ring tag and comment data (function block diagrams, tags, comments, and
annotations) to flash memory. The data in flash memory is backed up for
LCB01/03/05 Ver. 3.0 or later, and the easy backup operation will not be per-
formed correctly if these operations are performed.
This backup function is used when backing up data a PLC, including the CPU
Unit, Motion Control Units, DeviceNet Units, and Serial Communications
Units/Boards, or when all Units are replaced.
Note Select Execute - Backup from the CX-Process Tool menus to
backup RAM data to the flash memory before performing the easy
backup operation after downloading specific function blocks or
ITEMs or downloading only the user link table or a sequence table
online (all of these are possible while the Loop Controller is operat-
ing) if the downloaded data is also to be backed up to the Memory
Card
