Glossary
Device replacement without removable media/programming device
IO Devices having this function can be replaced easily:
● A removable medium (such as SIMATIC Memory Card) on which the device name is
stored is not required.
● The device name does not have to be assigned using the programming device.
Instead of being assigned a device name from the removable medium or programming
device, the IO Device is now assigned a device name by the IO Controller.
The IO Controller uses the configured topology and the correlations derived from the IO
Devices. The configured target topology must agree with the actual topology.
Diagnostics
The detection, localization, classification, visualization and further evaluation of errors,
disturbances and messages.
Provides monitoring functions which are executed automatically when the system is in RUN.
Increases plant availability by reducing commissioning times and down times.
Distributed I/O systems
I/O systems that are not integrated into the central CPU rack, but rather at distributed remote
locations. Example:
● ET 200M, ET 200X, ET 200L, ET 200S, ET 200 SP, ET 200pro, ET 200eco PN
● DP/AS-I Link
● S5-95U with PROFIBUS-DP slave interface
● Further DP slaves supplied by Siemens or other vendors.
Electrically isolated
The reference potentials of the control and load circuit of isolated I/O modules are electrically
isolated, for example, by means of optocoupler, relay or transformer. I/O circuits may be
connected to the same potential.
Equipotential bonding
Electrical connection (equipotential bonding conductor) that keeps electrical equipment and
extraneous conductive objects to the same or almost the same potential in order to prevent
disturbing or dangerous voltages between those objects.
Fast Ethernet
Fast Ethernet describes the standard for transferring data with 100 Mbps. This transfer
technology used the 100 Base-T standard for this.
