Features of Common Type 1:N Allocation
•
Data communications are 1:1 between the master node and slave nodes.
•
All slave nodes receive the data sent by the master node.
•
The master node receives all data sent by the slaves. The reception size
for the master node is thus the node send data size times the number of
slave nodes.
•
Slaves do not send or receive data with other slaves.
•
Area 1 is selected from the bit-access areas (e.g., CIO Area) and area 2 is
selected from word-access areas (e.g., DM Area).
•
Data link areas are allocated in ascending order of node addresses.
•
Data link participation can be specified for each node.
•
The same area classification can be used for both Area 1 and Area 2,
provided that the same addresses are not used (CS/CJ-series Controller
Link Units with unit Ver. 1.2 or later).
