A register is a 16-bit wide storage area for data which can be accessed and
addressed as a unit by some of the Modbus Function Codes.
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.
