first relay no. +3 is OFF.
Use the SET instruction or KEEP instruction to turn the relay ON/OFF.
Assigning data memory addresses
200 DM addresses, including the first DM no., are assigned.
The assigned DM addresses have the following functions.
■ Number of data bytes
The number of bytes in the first DM no. +0 and the first DM no. +100 becomes a
binary value. Write the binary data using the LDA/STA instruction or DW instruction.
■ Text data
Enter the text data in ASCII, by byte per DM. ("00" is entered in the 8 high-order bits
and ASCII code is entered in the 8 low-order bits.)
Write the text data using the LDA/STA instruction or DW instruction.
