Depending on the used Modbus function code a single register or multiple
registers sequentially located can be accessed.
Modbus differs Input Registers (FC 4) and Holding Registers (FC 3, 6, 16,
23).
Remanent memory holds its data even after power-off, for instance flash
memory is remanent. It is also called non-volatile memory.
A connector type often used for Ethernet connection. It has been
standardized by the Federal Communications Commission of the USA
(FCC).
A communication system for industrial Ethernet designed and developed by
Bosch-Rexroth and supported by sercos International.
A network component connecting multiple communication partners (or even
entire branches of a network) with each other. A switch is an intelligent
network component which analyzes network traffic in order to decide on its
own. For the connected communication partners a switch behaves
transparently.
Synchronization cycle of the master

Unconnected Message Manager
Versatile Automation Random Access Network
A communication system for industrial Ethernet based on the DIAS-BUS
developed by Sigmatek. The system is supported by the VARAN-BUS-
NUTZERORGANISATION (VNO).
A watchdog timer provides an internal supervision mechanism of a
communication system. It supervises that an important event happens
within a given timeframe (the watchdog time which can be adjusted
accordingly, for instance by a parameter in the
causes an alarm otherwise (usually this is accomplished by changing the
operational state of the communication system to a more safe state).
