IO data communicated over
RT uses EtherType 0x8892.
uses the acyclic slots of the
communications protocol and does not interfere with co-existing automation processes. The commands are based on the following use cases:
is defined by PROFIBUS and
International (PI) and backed by the INTERBUS Club and, since 2004, is part of the IEC 61158 and IEC 61784 standards.
IO system consists of the following devices:
Every module within a
network has three addresses:
IO connection life-cycle describes the connection between a
IO Controller and IO Device. The connection allows the cyclic exchange of process IO data, and the acyclic handling of alarms. The
IO connection life-cycle consists of address resolution, connection establishment, parameterization, process IO data exchange / alarm handling, and termination.
IRT uses the transparent clock mechanism to synchronize
IRT devices. The transparent clock mechanism is specified in IEEE 1588-2008 (1588 V2). This creates one control loop between the master clock and slave clocks.
PROFIsafe (PROFIBUS safety or
safety) is a safety communication technology for distributed automation. Its specification for PROFIBUS DP and PROFIBUS PA was published first in 1999. Extensions for the Ethernet based
IO followed in 2005.
Interfacing to peripherals is implemented by
IO. It defines the communication with field connected peripheral devices. Its basis is a cascading real-time concept.
IO defines the entire data exchange between controllers (devices with "master functionality") and the devices (devices with "slave functionality"), as well as parameter setting and diagnosis.
IO is designed for the fast data exchange between Ethernet-based field devices and follows the provider-consumer model. Field devices in a subordinate PROFIBUS line can be integrated in the
IO system seamlessly via an IO-Proxy (representative of a subordinate bus system). A device developer can implement
IO with any commercially available Ethernet controller. It is well-suited for the data exchange with bus cycle times of a few ms. The configuration of an IO-System has been kept similar to PROFIBUS.
IO always contains the real-time concept.
Note: PROFIBUS DP and PROFIBUS PA should not be confused with
IO, process data and alarms are always transmitted in real time (RT). Real time in
is based on definitions of IEEE and IEC, which allow for only a limited time for execution of real-time services within a bus cycle. The RT communication represents the basis for the data exchange for
IO. Real-time data are treated with a higher priority than TCP(UDP)/IP data. RT provides the basis for the real-time communication in the area of distributed periphery and for the
component model. This type of data exchange allows bus cycle times in the range of a few hundred microseconds.
Communications between the controller and drives is done through
, PROFIBUS, or Ethernet.
Protocols for Industrial Ethernet include EtherCAT, EtherNet/IP,
, POWERLINK, SERCOS III, CC-Link IE, Modbus/TCP.
PROFIenergy is a profile of the
communications protocol that allows the power consumption of automation equipment in manufacturing (such as robot assembly cells, laser cutters and sub-systems such as paint lines) to be managed over a
network. It controls energy usage during planned and unplanned breaks in production. No external hard-wired systems are required.
The bandwidth reservation method reserves time (bandwidth) on the network for
frames sent via IRT. A separate time domain is created at the beginning of a network cycle, during which all IRT frames are sent. After the IRT time domain is completed,
RT and finally non-time-critical TCP/IP frames are sent.
IO device is identified on the
network by its station name. Connection establishment, parameterization and alarm handling are implemented with User Datagram Protocol (UDP), which requires that the device also be assigned an IP address. After identifying the device by its station name, the IO controller assigns the pre-configured IP address to the device.
Alarm notifications are exchanged acyclically between the IO Controller and IO Device as events and faults occur during this phase in the
IO connection life-cycle.
profiles for encoders, for example. Other profiles have been specified for motion control (PROFIdrive) and Functional Safety (PROFIsafe). A special profile for trains also exists.
Controls for the newer KRC2 type use the Windows XP operating system. Systems contain a CD-ROM drive and USB ports, Ethernet connection and feature optional connections for Profibus, Interbus, DeviceNet and
Group members have and continue to develop and publish numerous open source tools for scanning, fingerprinting, security evaluation and password bruteforcing for ICS devices. These devices work over industrial protocols such as modbus, Siemens S7, MMS, ISO EC 60870,
