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.

•
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.
