Introduction Section 6-1
C200HX/HG/HE PLCs
Note 1. Words in the Internal Relay Area 1 (IR 000 to IR 235) and Special Relay
Area 1 (SR 236 to SR 255) are continuous in memory, and any range of
words within these areas can be transferred in a single operation. The
same is true for Special Relay Area 2 (SR 256 to SR 299) and Internal Re-
lay Area 2 (IR 300 to IR 511). You cannot, however, transfer data in a range
that crosses the boundary between Special Relay Area 1 (SR 236 to SR
255) and Special Relay Area 2 (SR 256 to SR 299).
SR 253 to SR 255 cannot be written at the source node, even if they are
specified by the RECV instruction’s beginning receive word at the source
node.
2. For details on extended DM Area and the number of banks, refer to the op-
eration manual for the PLC model that is being used.
CVM1 and CV-series PLCs
Note 1. Writing is not possible to words G000 through G007 in the CPU Bus Link
Area.
2. Writing is not possible to words A256 through A511 in the Auxiliary Area.
3. Expansion DM can be used by mounting an Expansion DM Unit to a
CV1000/2000 or CVM1-CPU11/21 PLC. A maximum of eight banks can be
used, depending on the type of Expansion DM. For details, refer to the
CVM1 and CV-series PLC operation manuals.
