General purpose digital I/O
This section describes the general purpose 24V I/O (Gray terminals) and the configurable I/O
(Yellow terminals with black text) when not configured as safety I/O. The common specifications
in sectionCommon specifications for all digital I/Oon page31 must be observed.
The general purpose I/O can be used to drive equipment like pneumatic relays directly or for
communication with other PLC systems. All digital outputs can be disabled automatically when
program execution is stopped, see more in partPart II PolyScope Manualon page85. In this
mode, the output is always low when a program is not running. Examples are shown in the
following subsections. These examples use regular digital outputs but any configurable outputs
could also have be used if they are not configured to perform a safety function.
Load controlled by a digital output
This example shows how to connect a load to be controlled from a digital output, see below.
