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.

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.

A data packet used in serial communication.

TFE

transparent factory Ethernet. Schneider Electric’s open automation framework

based on TCP/IP.

transmission. For example, in a CAN-based network, a PDO is described as a

TxPDO of the device that transmits it.
