Description of Operation Section 3-2
This compares data in the function block data file on the Memory Card with
the data in RAM in the Loop Controller. When the power ON button is
pressed, the MCPWR indicator on the front of the CPU Unit flashes once and
remains lit while the data is being compared. If the data matches, the indicator
will go out when the comparison is completed. If the data does not match, the
MCPWR indicator on the front of the CPU Unit will flash.
Note (1) The data that is backed up has changed from the data in RAM to the data
in flash memory for LCB01/03/05 Ver. 3.0 or later. This prevents verifica-
tion errors from occurring during the easy backup operation when func-
tion block parameter ITEMs have been changed in RAM data for Loop
Controller program operations. (A verification error will occur with earlier
versions.)
(2) Use an OMRON Memory Card. Operations may be unstable if a non-
OMRON Memory Card (compact flash memory) is used.
Note (a) A Memory Card can be written up to approximately 100,000
times. (Each write operation to the Memory Card must be count-
ed regardless of the size of the write.) Be particularly careful not
to exceed the life of the Memory Card when writing to it from the
ladder program.
(b) The HMC-AP001 Memory Card Adapter is shown below.
For details on the Memory Card, refer to the SYSMAC CS-series Program-
mable Controllers Operation Manual (Cat. No. W339).
Note Online operations from the CX-Process Tool software are restricted as shown
in the following table during backup operations to a Memory Card for Loop
Controller Ver. 3.0.
