Table Data Processing Instructions Section 3-16
Operands N: Table number
Indicates the table number. N must be between 0 and 15.
R: Record number
Indicates the record number of the desired record. R must be 0000 to FFFE
hexadecimal (0 to 65,534). Record numbers begin with 0, so the valid record
numbers are 0 to NR–1 for a table with NR records.
D: Destination Index Register
Indicates the desired Index Register. D must be IR0 to IR15.
Operand Specifications
Description SETR(635) stores the PLC memory address of the first word of the specified
record in the specified Index Register. The following diagram shows the basic
operation of SETR(635).
Flags
Precautions The record table must be defined in advance with DIM(631).
