7 Basic Instructions
7.1 Contact Instructions
 Functions
LD,LDI
 LD is the A contact operation start instruction, and LDI is the B contact operation start instruction.They read ON/OFF infor-
mation from the designated device (if a word device bit has been designated, this becomes the 1/0 status of the designated
bit), and use that as an operation result.
AND,ANI
 AND is the A contact series connection instruction, and ANI is the B contact series connection instruction. They read the
ON/OFF data of the designated bit device (if a bit designation has been made for a word device, the 1/0 status of the des-
ignated bit is read), perform an AND operation on that data and the operation result to that point, and take this value as the
operation result.
OR,ORI
 OR is the A contact single parallel connection instruction, and ORI is the B contact single parallel connection instruction.
They read ON/OFF information from the designated device (if a word device bit has been designated, this becomes the 1/0
status of the designated bit), and perform an OR operation with the operation results to that point, and use the resulting
value as the operation result.
[Remark]
 Designate the bit of the word devices in hexadecimal. Bit b11 of D0 would be D0.B.
 Arithmetic errors
 There are no arithmetic errors with LD,LDI,AND,ANI,OR,or ORI instructions.
