IO Devices
I/O devices consist of DAPs and I/O modules.
The functions and properties of these devices are described in a GSD file.
• DAP (Device Access Point): This is an Ethernet access point and is used by means of a communi-
cation program.
• I/O Module: Consists of the Slot, Subslot, and Index below. An I/O module has one or multiple slots.
• Slot: Indicates the location of the I/O module in the I/O device.
• Subslot: I/O interface inside the slot. This defines data types such as bit data and byte data, and
the meanings of the data types.
• Index: Data in a Subslot.

4 Controlling Operation and Data Output with PROFINET
Overview
Supports the basic functions of RT communication.
This class adds network diagnosis and redundancy functions
used in process automation and other applications.
Supports IRT communication that realizes reliable synchroniza-
tion.
Real-time data communication between the I/O controller and I/O devices
at determined cycles. Set by I/O data CR.
Used for parameter settings, I/O device configuration, and reading of de-
vice information. Set by record data CR.
Communication for the purpose of sending alarms and statuses from I/O
devices to the I/O controller. Set by Alarm CR.
Allows additional Network Diagnostics via Management Information Base
2 (MIB2) and Lower Link Layer Discovery Protocol-MIB(LLDP-EXT-MIB).
Can also gather diagnostic information using acyclic PROFINET services.
Controller for external and other devices.
Reader device connected to the I/O controller. This code reader is an I/O
device.
PC or other device used for maintenance and diagnosis.
