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 |
| 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. |
| 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 |
| provides reliable |
| 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 |
| TxPDO of the device that transmits it. |
