Appendix 4 List of Special Relay Areas
*1 The programmable controller CPU with firmware version "28" or later supports these special relay areas. However, there are no
restrictions on the version of the R00CPU, R01CPU, and R02CPU.
*2 There are restrictions on the firmware version of the supported CPU module and software version of the engineering tool. (

information for the multiple
CPU dedicated instruction
(for CPU No.1)
Off: The specified number
of blocks is reserved
On: The number of blocks
specified in SD796 is
not reserved
• This relay switches to on when the
number of remaining blocks in the
dedicated instruction transfer area to be
used in the multiple CPU dedicated
instruction (target machine: CPU No.1)
drops below the number of blocks
specified in SD796. This relay is also on
when the instruction is being executed.
• This relay switches to off when there exist
free blocks during the END processing.

• This relay switches to on when the
number of remaining blocks in the
dedicated instruction transfer area to be
used in the multiple CPU dedicated
instruction (target machine: CPU No.2)
drops below the number of blocks
