Features of 1 to 1 Type 1:N Allocation
•
Data communications are 1:1 between the master node and slave nodes.
•
All slave nodes receive part of the data sent by the master node. In addition,
each slave node receives unique data from the master node (see a to d in
figure).
•
The master node receives all data sent by the slaves. The data sizes are
fixed for all nodes.
•
Slaves do not send or receive data with other slaves.
•
One area is selected from the bit-access areas (e.g., CIO Area) or
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.
Chain Type Settings
No. Item Description of function
(1) Link Area and Start Set the area and the start data link
Word word.
(2) Master, Common Set the send size of the data to send
Send Words from the master node to all slave
nodes. The same size of data is sent
to all nodes.
(3) Each Node, Set the send size of data for each
Receive and Send node to send to the next node.
(4) Nodes Set the nodes participating in the data
links.
(5) Status start word Set the start word to store data link
status. (If 0 words is set, the default
area will be used.)
Features of Chain Type 1:N Allocation
•
Data communications are 1:1 between the master node and slave nodes.
•
All slave nodes receive part of the data sent by the master node (1a in figure).
•
The master node receives all data sent by the slaves. The data sizes are fixed
for all nodes.
•
Each slave nodes receives data from the previous node and then sends data
to the next node. Data is thus passed in ascending order of the nodes
participating in the data link.
•
One area is selected from the bit-access areas (e.g., CIO Area) or
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.
