General Purpose Digital I - Elite EC66 User Manual

8.3.3 General purpose digital I/O
This section introduces the general purpose 24V I/O. The common specifications in section
4.3.1 must be followed. The general purpose I/O may be used to directly drive the equipment,
such as the pneumatic relay, or to communicate with other PLC systems. All digital outputs may
be disabled automatically when program execution is stopped. Refer to Part II for details. In this
mode, the output shall be the high level all the time when the program does not run. Several
examples are shown in the section below. The regular digital outputs are taken in these examples,
however this type of outputs may also be used if the configurable output is not configured to
perform the safety function.
