(b) When using a 32-bit instruction for the link register
For a 32-bit instruction, two consecutive points of the data register (Wn and Wn+1) are the target of the
processing.
The lower 16 bits correspond to the link register number (Wn) specified in the sequence program, and the
higher 16 bits correspond to the specified link register number + 1.
When W12 is specified in the DMOV instruction, W12 represents the lower 16 bits and D13 represents
Ex.
the higher 16 bits.
Data of -2147483648 to 2147483647 or 00000000
register. (The most significant bit in a 32-bit structure is a sign bit.)
(2) Retention of stored data
The data stored in the link register are held until other different data are stored.
Note that the stored data are initialized when the CPU module is powered off or reset.
To use the link device in the network module exceeding link register points of the CPU module (default: 8192 points), change
the link register points in the Device tab of the PLC Parameter dialog box.
(3) Using the link register in a network system
Network parameters must be set.
The area range that is not set by network parameters can be used as a data register.
