I/O modules and variations

Technical Description:

This module allows increased airand creepage distances between different field voltages within a node.

There are two different separation modules. The 750-616 module does not have printing. The 750-616/030-000 has "24 V DC /230 V AC" printed on the front.

4.9.1.1.2 End module

750-600

Technical Description:

After the fieldbus node is assembled with the correct buscoupler and selected I/O modules, the end module is snapped onto the assembly. It completes the internal data circuit and ensures correct data flow. This module is a necessary component to all WAGO fieldbus nodes.

General

5 LON

LON (Local Operating Network) is a multimaster capable communication network for decentralized industrial applications with time-uncritical requirements. Particularly LON is developed for building automation. Central tasks are splitted in decentral tasks. So in every distributed intelligence (node) an application processing occurs locally, without the interruption of the other nodes in the network.

LonWorks® Technology encompasses a complete platform for the creation of automation networks and was launched on the market by the American company Echelon® Corporation.

Due to the large spatial distribution of the bus subscribers and due to the large number of communication media in a building or a machine line, all control and regulation tasks are located directly to sensors and actuators, in other words distributed or decentralized.

The sensors detect events such as key operation, light level, temperature, humidity, movement etc. They send messages to the actuators to carry out the commands. Sensors and actuators can be logically interconnected to perform more complex functions.

In addition, LON is able to merge functions of widely differing systems. For application examples, refer to the integrated room control of light, sun protection, ventilation and air conditioning. Here further LON sub-systems, such as automatic doors, elevators, escalators or safety lighting can be seamlessly integrated.

For more complex installation systems the use of the WAGO LON bus system results in a notable reduction of commitment to be put into projecting, wiring, start-up and trouble-shooting. A dramatic cost reduction can be achieved compared to other decentral control systems, such as, for example the European Installation Bus (EIB).

Prerequisite of the EIB with was developed for spatial applications in building automation and which is a "totally" decentral control system is that each individual actuator, sensor and controller is of an "intelligent" nature. Such "intelligent" components are very expensive.

In contrast to the above, LON in accordance with the concept developed by WAGO, is a "semi-"decentralized, multi-network capable communication system which requires per distribution - in a building for instance per storey - in each case only one "intelligent" component, the so-called bus node.

Each node allows the connection of a large number of sensors, actuators and operating units in the form of conventional standard components, which come, of course, much cheaper.
