2.1.4 Data Area Specifications Using Tag/Instance
In the cyclic communication, the data send and received areas are specified using "Tag" or
"Instance".
• For "Tag", the areas are specified by symbols. For "Instance", they are specified by
numbers.
•
For some target devices, only either of "Tag" and "Instance" may be available.
•
In the connection of "Exclusive Owner", the receive area of each target is specified by
another tag or instance.
(Note) Even when specifying by tag, numbers are assigned to packets during the actual cyclic
communication.

KEY POINTS
• In each connection, the sizes of the data areas which correspond to the
originator and target should be the same.
•
For the FP0H, the data areas of each connection can be allocated to the
operation memories in a maximum of 8 areas. Device names that can be
allocated are WX, WY, WR, WL, LD, and DT. For the automatic allocation, the
WL and LD areas are used.
