INTRODUCTION

c-pro 3 NODE kilo is a range of programmable controllers for applications in refrigeration and air conditioning sectors. The controllers have a considerable number of inputs and outputs; they allow to realize a flexible, modular and expandable control devices network.The variety of available communication ports (RS-485, CAN, USB and Ethernet) and supported communication protocols make easier the integration of the devices in systems. The application software can be realized through the UNI-PRO 3 development environment for programmable controllers. For information on the use of the BACnet communication protocol please consult the PICS.

The actual UNI-PRO 3.13 version implements a BACnet® standardized device profile B-ASC, which doesn’t require the managing of Scheduler and Calendar objects, instead required for the B-AAC profile.
