Example of hotel room automatization using LPC-2 modules

Described is technical solution for smart root based on LPC-2 equipment.

Using central management system hotel manager can monitor energy consumption and manage energy saving. Integrated card system supports several access levels, based on services that customer paid. Another important aspect is alarming in case of (extraordinary) events in the building (water leakage, SOS, room service,...). System can also be integrated with optical network for using additional services, such as Internet access, PayTV, IP telephony, etc.

Using global variables and interrupt triggering of PLC application

This example illustrates the use of global variables for connecting POUs that run in parallel. Another feature, which is used in this application, is interrupt triggering of one PLC application (i.e. an alarm that needs immediate handling occurs), while the main application runs cyclically.

Using Modbus TCP and retain variables

This application uses (reads/writes) variables, which are updated over Modbus TCP network protocol. Also, retain (non-volatile) variable, which holds it's value after powering the controller off, is used for POU initialization.

Included is also a project with all necessary settings for Modbus Tester tool, used for checking PLC application registers over Ethernet network, and a memory map of all available Modbus variables.

Using function blocks

In this project all available function blocks from "Library" section are used. The main purpose is to show the correct use of all function blocks, but it can also be used to check if any changes to these libraries were introduced with new LPC Composer updates.
