6-3 Backing Up DM Area to Flash Memory
The contents of DM 0000 to DM 6143 can be written to flash memory by turn-
ing ON SR 25200 (DM Flash Memory Backup Bit) in PROGRAM mode.
(SR 25200 will turn OFF automatically when transfer has been completed.)
The data stored in flash memory can be read back to DM 0000 to DM 6143 by
using the XFER(70) instruction as shown below.

7-1 Applicable Directives
• EMC Directives
• Low Voltage Directive
7-2 Concepts
EMC Directives
OMRON devices that comply with EC Directives also conform to the related
EMC standards so that they can be more easily built into other devices or
machines. The actual products have been checked for conformity to EMC
standards (see the following note). Whether the products conform to the stan-
dards in the system used by the customer, however, must be checked by the
customer.
EMC-related performance of the OMRON devices that comply with EC Direc-
tives will vary depending on the configuration, wiring, and other conditions of
the equipment or control panel in which the OMRON devices are installed.
The customer must, therefore, perform final checks to confirm that devices
and the overall machine conform to EMC standards.
Note Applicable EMC (Electromagnetic Compatibility) standards are as follows:
EMS (Electromagnetic Susceptibility): EN61000-6-2
EMI (Electromagnetic Interference): EN50081-2
(Radiated emission: 10-m regulations)
Low Voltage Directive
Always ensure that devices operating at voltages of 50 to 1,000 VAC or 75 to
1,500 VDC meet the required safety standards for the PLC (EN61131-2).
