Complete Link
The data from all nodes in the Serial PLC Links are reflected in both the Polling Unit and the Polled
Units.
The only exceptions are the addresses of Polled Units that are not present in the network. These
data areas are undefined in all nodes.
Example: Complete Link Method, Highest Unit Number: 3
In the following diagram, Polled Unit No. 2 is a Unit not present in the network, so the area allocated
for Polled Unit No. 2 is undefined in all nodes.
Example for Ten Link Words (Maximum Number of Words)
Each CPU Unit (either CP2E, CP1E, CP1L, CP1H, or CJ2M) sends data to the same words in all
other CPU Units for the Polling Unit and all Polled Units. Data is sent between the words that are
allocated to the Polling Unit and Polled Units according to unit numbers.
