Flags
Precautions Records in a registered table are identified by their record numbers, which
range from 0 to NR–1.
Depending on the settings for the record length (LR) and number of records
(NR), it is possible that a single table (from TB and TB+LR
×NR–1) will overlap
two data areas. Verify that no problems will arise before specifying a table that
overlaps a data area boundary.
Examples When CIO 0.00 is ON in the following example, DIM(631) defines record table
number 2 with three 10-word records. The table begins at D300.
3-16-6 SET RECORD LOCATION: SETR(635)
Purpose Writes the location of the specified record (the PLC memory address of the
beginning of the record) in the specified Index Register.
