Parallel Elements
You may also have to join contacts in parallel. The OR instruction allows you to do this. The
following example shows two contacts in parallel and a single output coil. The instructions
would be STR X0, OR X1, followed by OUT Y0.
Joining Series Branches in Parallel
Quite often it is necessary to join several groups of series elements in parallel. The Or Store
(ORSTR) instruction allows this operation. The following example shows a simple network
consisting of series elements joined in parallel.
Joining Parallel Branches in Series
You can also join one or more parallel branches in series. The And Store (ANDSTR) instruction
allows this operation. The following example shows a simple network with contact branches
in series with parallel contacts.
Combination Networks
You can combine the various types of
series and parallel branches to solve most
any application problem. The following
example shows a simple combination
network.
