> K9,999, D1103 < K2,000 or D1103 > K9,999.
3. SA/SX/SC: 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 ~ K1,599), D1102 (number of data to be read in file register K1 ~ k1,600), and D1103 (device for
storing read data, starting from designated D, K2,000 ~ K4,999).
4. In SA/SX/SC, the reading of data from file register to data register D will not be executed if D1101 < 0, D1101 >
K1,599, D1103 < K2,000 or D1103 > K4,999.
5. When the reading of data from file register to data register D starts, PLC will stop the reading if the address of
file register or data register exceed their range.
6. In PLC program, only API 148 MEMR and API 149 MEMW can be used to read or write the file register. See
2.8.3 for more information on file registers.
7. File registers do not have actual addresses in it. Reading and writing of file registers can only be done through
API 148 MEMR, API 149 MEMW or peripheral devices HPP and WPLSoft.
8. If the address in the file register to be read exceeds its range, the read value will be 0.
9. Special relays of file register and other relevant special registers:
Flag
Function
M1101
Whether to enable the function of file register; latched; default = off
Special D
Function
D1101
Start address in file register. SA/SX/SC: K0 ~ K1,599; EH/EH2/SV:
K0 ~ K9,999; latched; default = 0
D1102
Number of data to be read in file register. SA/SX/SC: K1 ~ K1,600;
EH/EH2/SV: K1 ~ K8,000; latched; default = 0
D1103
Device for storing read data, starting from designated D. SA/SX/SC:
K2,000 ~ K4,999; EH/EH2/SV: K2,000 ~ K9,999; latched; default =
2,000
