Glossary of Terms

FMEA
FMEA = F ailure M ode and E ffects A nalysis.
Method of reliability engineering, to find potential weak points. Within the framework of quality or
security management, the FMEA is used preventively to prevent faults and increase the technical
reliability.

FRAM
FRAM, or also FeRAM, means Fe rroelectric R andom A ccess M emory. The storage operation and
erasing operation is carried out by a polarisation change in a ferroelectric layer.
Advantages of FRAM as compared to conventional read-only memories:
• non-volatile,
• compatible with common EEPROMs, but:
• access time approx. 100 ns,
• nearly unlimited access cycles possible.

G
Gateway
Gateway = access, coupler.
Gateways enable connection of completely different systems. Gateways are used when two
incompatible network types are to be connected by converting the protocol of one system to the
protocol of the other system.
Example: connection between AS-i and higher-level fieldbus systems such as

Ethernet DP,

DeviceNet, Interbus-S or other interfaces, e.g. RS-485. The device includes an AS-i master which is
directly coupled to the

host interface (e.g. Ethernet DP slave).
>
Gateway transfer time
The time that is needed for the input data in the DP-RAM of the AS-i master to be copied into the
output data of the netX, and vice versa. The distance from DP-RAM to DP-RAM is decisive.

GSDML
GSDML = G eneric S tation D escription M arkup L anguage.
Description language which can describe the characteristics of a device family across several levels.
In this XML scheme, as much as possible of the semantics of the

GSD was adopted.
