11 INSTRUCTIONS AND FUNCTIONS
• The following processing is performed if file registers are specified as the device
memory to be written to:
(1) If the file registers have never been changed in the PLC CPU, data is written to
the file registers of block number 0.
(2) If the block number of the file registers has been changed in the PLC CPU, data
is written to the file registers of the new block number.
1) When the block number has been changed using the RSET instruction of the
microcomputer program package of the type SW GHP-UTLPC-FN1 utility
software package or the type SW SRX-FNUP software package.
2) When the block number has been changed using the RSET instruction.
Processing cannot be performed normally with processing code 1 if the block number of the file
registers has been changed to 29 or greater using the RSET instruction. In this case, use
processing code 4 (writing to extension file registers) instead.
Program Example
(1) Program example for a format 1 control table
100 ' A program example that writes data to device memory of the PLC CPU
110 DIM TBL%(10),A%(20) : 'Defines arrays
120 TBL%(0)=255 : 'Specifies the station number to
communicate with to the local station
130 TBL%(1)=1 : 'Specifies to write to device memory
140 TBL%(2)=2 : 'Specifies word units
150 TBL%(3)=3 : 'Specifies internal relays M
160 TBL%(4)=0 : 'Specifies the device number
170 TBL%(5)=1 : 'Specifies the number of words to be
written
180 A%(0)=&H5 : 'Turns M1 and M3 ON and all others OFF
190 PCWT TBL%( ),A%( ) : 'Executes the write operation
