Glossary
Automation system
is a controller of the SIMATIC S7 series such as a SIMATIC S7-1200.
Controller
General term for devices and systems with which the HMI device communicates, e.g.
SIMATIC S7.
Diagnostics
Diagnostics enable you to determine if the signals are being correctly registered in the fail-
safe HMI device.
EMC
Electromagnetic compatibility (EMC) refers to a state in which technical equipment does not
disturb other equipment with unwanted electrical or electromagnetic effects. Electromagnetic
compatibility deals with technical and regulatory questions of undesired, mutual influence in
electrical engineering.
Failsafe
Capability of a technical system to remain in a safe state or switch to another safe state
immediately in the event of a failure or fault.
Fail-safe system, F system
A fail-safe system is used to control production processes in which immediate shutdown
results in a safe system status. This means that a fail-safe systems control processes that do
not present a danger to people or the environment if a direct shutdown of the plant occurs.
Fail-safe systems are used in plants with high safety requirements.
GSD
The GSD file contains all the properties of a DP slave or IO device. STEP 7 requires a GSD
file for each DP slave and for each IO device to allow the DP slave or IO device to be
selected in the module catalog of HW Config.
