Glossary

 

 

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

The process of absorbing and clipping voltage transients on an incoming AC line or

suppression

control circuit. Metal-oxide varistors and specially designed RC networks are

 

frequently used as surge suppression mechanisms.

 

 

T

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.
