Operands:
S
: Device for storing the written data (starting from the designated D) m: Address in the file register to be written
n
: Number of data to be written at a time
Explanations:
1. Range
of
S
: D2000 ~ D4999 (SA/SX/SC); D2000 ~ D9999 (EH/EH2/SV)
2. Range
of
m
: K0 ~ K1,599 (SA/SX/SC); K0 ~ K9,999 (EH/EH2/SV)
3. Range
of
n
: For 16-bit instruction K1 ~ K1,600 (SA/SX/SC), K1 ~ K8,000 (EH/EH2/SV); For 32-bit instruction K1
~ K800 (SA/SX/SC), K1 ~ K4,000 (EH/EH2/SV)
4. See the specifications of each model for their range of use.
5. Flag: M1101. See explanations below.
6. SA/SX/SC/EH/EH2/SV uses this instruction to read the data in data registers and write them into file registers.
7. SA/SX/SC offers 1,600 16-bit file registers.
8. m and n of SA/SX/SC do not suppot E and F index register modification.
9. EH/EH2/SV offers 10,000 16-bit file registers.
10. If S, m and n fall without their range, operation error will occur. M1067, M1068 = On and D1067 will record the
error code H’0E1A.
Program Example:
1. When X0 = On, the 32-bit instruction DMEMW writes 100 32-bit data starting from D2001 and D2000 into
address 0 ~ 199 in the file register.
2. When X0 = On, the instruction will be executed. When X0 = Off, the instruction will not be executed and the
previously data written in will remain unchanged.

File Register:
1. EH/EH2/SV: When the PLC is powered, it will decide whether to automatically send the data in the file register
to the designated data register by M1101 (whether to enable the function of file register), D1101 (start address
in file register K0 ~ K9,999), D1102 (number of data to be read in file register K1 ~ k8,000), and D1103 (device
for storing read data, starting from designated D, K2,000 ~ K9,999).
2. In EH/EH2/SV, the reading of data from file register to data register D will not be executed if D1101 < 0, D1101
