8.5 I/O Device
An I/O device is used to communicate with hardware modules for digital input and output signals. For
description on I/O devices and how to set up, see chapter: I/O.
The I/O device, as well as Stacklight, Indicator Box, and Operator Panel, can map all boolean signals
located in the Digital_In_Out group and in the Shared_Variables group. Boolean outsignals starting with
“SO_” in the Fieldbus_Variables group can also be mapped by these devices since they belong to the
shared signals. Se PLC Areas for more information about these areas in the PLC.
