System overview
Example
The Easy Loop connection system consists of a communications module and up to 16 proces-
sors.
Up to eight processors may be connected to each of the two ports on the communications
module.
The Easy Loop connection system forms a ring in which the processors are numbered in
sequence, beginning with Line 1.
The telegrams from the individual processors are strung in this sequence and sent to the
controller from the communications module as a data chain. The telegrams can be evaluated
separately in the host controller (
see “Protocol sequence” on page 2 ).
The processors may be interchanged with each other within the connection system, since
the processors are not addressed.
Additional processors may be connected at any point, whereby only the order of the tele-
grams changes.
The ring must be closed.

In the following example the first processor in Line 1 sends the first telegram (1st read location)
and the first processor on Line 2 sends telegram number 5 (5th read location):
