LN: Teleprotection communication interfaces Name: ITPC
For a description of this LN, see IEC 61850-5. The LN ITPC comprises all information for communication channel setting and supervision. ITPC is not intended to generate direct process data objects. Thus, it does not contain the input and output data objects to be transmitted and it has no ‘operate’ data objects object.

NOTE EEHealth is used to indicate the state of the communication channel, whereas PhyHealth is used to indicate the state of the (physical) communication device. If ITPC receives a GOOSE message with quality attribute “invalid" or “questionable" or no GOOSE message at all within Tmax, it will set PhyHealth to "Warning". Other actions are a local issue. |

Logical nodes for mechanical and non-electric primary equipment LN group К
Modelling remarks
This group of logical nodes represents various devices that can be supervised, controlled or operated but that are not primarily of electrical nature. This group includes devices like tanks,
valves, fans etc. Therefore, description and requirements are given in IEC 61850-5 with different level of detail.
LN: Fan Name: KFAN
Logical node KFAN shall be used to represent a fan. It can be seen as an extended nameplate that allows the temporary setting of data object.
