Simple Backup Function (Backup of Protocol Macro Data) Section 5-5
Note Abort Switch Precaution
The Abort Switch can be used to abort the sequence that is being executed.
The Abort Switch can be turned ON from a ladder diagram or from a Program-
ming Device. It will be turned OFF automatically by the system when abort
processing has been completed. Do not attempt to force the Abort Switch to
stay ON from a ladder diagram or from a Programming Device.
5-5 Simple Backup Function (Backup of Protocol Macro Data)
Overview The “-V1” versions of the CS-series Serial Communications Boards/Units
(CS1W-SCB21-V1, CS1W-SCB41-V1, CS1W-SCU21-V1, and CS1W-
SCU31-V1) and the CJ-series Serial Communications Units (CJ1W-SCU21(-
V1)/SCU31-V1/SCU41(-V1)*) support the Simple Backup Function when con-
nected to a CS1-H or CJ1-H CPU Unit.
Note *The CS-series Serial Communications Boards/Units without the “-V1” suffix
do not support this Simple Backup Function, but the CJ1W-SCU21/41 does
support this function even though the model number lacks the “-V1” suffix.
The CPU Unit’s Simple Backup Function will automatically backup, restore, or
compare the Protocol Macro data (both standard system protocol and user-
set protocol data) in the Serial Communications Board/Unit’s flash memory to
the CPU Unit’s Memory Card. The Protocol Macro data is backed up,
restored, or compared along with all of the data in the CPU Unit. (The Simple
Backup Function can be used with CS1-H and CJ1-H CPU Units only.)
When the Protocol Macro data in the Serial Communications Board/Unit is
written to the Memory Card by the Simple Backup Operation, the data is
saved as a Unit/Board Backup File with the filename shown below.
Note A Unit/Board Backup File for a Serial Communications Unit or Board is
referred to as a “Protocol Data File” in this manual.
Filename: BACKUP@@.PRM
(The value @@ is the unit address. A Serial Communica-
tions Unit’s unit address is the Unit number + 10 Hex. A
Serial Communications Board’s unit address is E1 Hex.)
The Protocol Data File is accessed from the Memory Card during read and
compare operations.
Note The following table shows the combinations of CPU Units and Serial Commu-
nications Board/Unit that support the Simple Backup Function.
