Status of DIP
Switch Pin 3 A395.12 The status of pin 3 on the DIP switch on the front of the CPU Unit
is written to this flag every cycle. Read-only
Manufacturing Lot
Number A310 and
A311 The manufacturing lot number is stored in 5 digits hexadecimal.
X, Y, and Z in the lot number are converted to 10, 11, and 12,
respectively.
Examples:
Lot number 23805
A310 = 0823, A311 = 0005
Lot number 15X05
A310 =1015, A311 = 0005 Read-only

Read Error Flag A751.11 ON when an error occurred in transferring DM initial values from
the DM initial value area in flash memory to the DM Area. Read-only
DM Initial Values
Save Execution
Error Flag A751.12 ON when the DM Initial Values Transfer Password (A752) is
incorrect or when the DM Initial values area was not specified
when starting to transfer DM initial values from the DM Area to
the DM initial value area in flash memory. Read-only
DM Initial Values
Save Error Flag A751.13 ON when an error occurred in transferring DM initial values from
the DM Area to the DM initial value area in flash memory. Read-only
DM Initial Values
Save Flag A751.14 ON while DM initial values are being transferred from the DM
Area to the DM initial value area in flash memory.
OFF when the transfer has been completed. Read-only
DM Initial Values
Save Start Bit A751.15 Turn ON this bit to start transferring DM initial values. This bit is
valid only when a correct password is stored in A752 and the DM
Area Initial Value Area is specified (i.e., when A753.00 is ON).
The system will turn this bit OFF automatically when the transfer
has been completed. Read/Write
DM Initial Values
Transfer Password A752 Set the passwords here to transfer DM initial values between the
DM area and the DM initial value area in flash memory. The
transfer will not be started unless the correct password is set.
The transfer is started when A751.15 is turned ON.
The password will be cleared by the system when the transfer
has been completed.
