standard
network
interface
An Advantys STB network interface module designed at moderate cost to support
the kind of configuration capabilities and throughput capacity suitable for most
standard applications on the island bus.
STD_P standard profile. On a Fipio network, a standard profile is a fixed set of configuration
and operating parameters for an agent device, based on the number of modules that
the device contains and the device’s total data length. Three types of standard
profiles are available—Fipio reduced device profile (FRD_P), Fipio standard device
profile (FSD_P), and the Fipio extended device profile (FED_P).
stepper motor A specialized DC motor that allows discrete positioning without feedback.
subnet A part of a network that shares a network address with the other parts of a network.
A subnet may be physically and/or logically independent of the rest of the network.
A part of an internet address called a subnet number, which is ignored in IP routing,
distinguishes the subnet.
surge
suppression
The process of absorbing and clipping voltage transients on an incoming AC line or
control circuit. Metal-oxide varistors and specially designed RC networks are
frequently used as surge suppression mechanisms.
TC thermocouple. A TC device is a bimetallic temperature transducer that provides a
temperature value by measuring the voltage differential caused by joining together
two different metals at different temperatures.
TCP transmission control protocol. A connection-oriented transport layer protocol that
provides reliable full-duplex data transmission. TCP is part of the TCP/IP suite of
protocols.
telegram A data packet used in serial communication.
TFE transparent factory Ethernet. Schneider Electric’s open automation framework
based on TCP/IP.
Tx transmission. For example, in a CAN-based network, a PDO is described as a
TxPDO of the device that transmits it.
