Serial Communications
Section 6-1
Example: Polling Unit Link Method, Highest Unit Number: 3
In the following diagram, Polled Unit No. 2 is a PT or a Unit not participating in
the network, so the corresponding area in the Polling Unit is undefined.
Example: Polling Unit Link Method, Number of Link Words: 10
The CPU Unit that is the Polling Unit (either CP1H or CJ1M) sends its data
(CIO 3100 to CIO 3109) to the same words (CIO 3100 to CIO 3109) in all
other CPU Units. The Polled Units send their data (CIO 3110 to CIO 3119) to
consecutive sets of 10 words in the Polling Unit. The Polling Units is a CP1H
CPU Unit in the following example, but it could also be a CJ1M CPU Unit.
(Only the first three Polled Units are shown below.)
