Bus Koppler: station headers

Configuration, Monitoring and Diagnostic: Phoenix Contact PC software for configuring, running and diagnosing the INTERBUS bus.

Data Process channel: channel for process data

Inputs/Outputs

INTERBUS: this bus uses the master-slave process. The master subscriber module manages and coordinates bus access. It transmits data to all the subscribers and receives data from them.

Installation Remote Bus: installation bus

Local Bus: local bus

The local bus modules are I/O modules used for building a remote sub-station in a control cabinet.

Object Dictionary: dictionary of objects. Contains all data needed to describe standard PMS-type objects for a specific device (Robot, etc.)

Peripherals Communication Protocol: communication protocol for peripherals (layer 2 of the OSI model). This fragments and reconstitutes messages during transmission. It makes available all the services needed for connection and disconnection, and the data transmission services.

Peripherals Message Specification: Specification of the Peripherals Messages. PMS is a user that follows the MMS model (in layer 7 of the OSI model). PMS formally describes the connection and disconnection services, as well as the services for transmitting the data made available by the PCP.

Standardized PMS communication services make sure the same communication interface is used for all equipment.

Remote Bus: interstation bus

All INTERBUS subscribers are connected to a ring structure (also called 'loop').
