3. GENERAL SPECIFICATIONS
The Dixell programmable controllers are all powered at 24Vac/dc and use a high speed performance 32-bit
ARM9 (200 MHz) microprocessor. The models differ in size (10 DIN or 4 DIN) and number of inputs and
outputs (analogue and digital).
One of the features that distinguishes the iPRO controllers is the vast range of connection options with
external devices, Dixell as well as other brands. CANBus, RS485 Master and Slave, and an Ethernet and
USB port provide maximum flexibility of integration with the outside world. MODBUS RTU protocol, one of
the most popular in the world, is used for serial communication.
Up to 80 MB of flash memory are entirely available to the user, according to the model. All the inputs and
outputs are fully configurable.
3.1 PROCESSING ENVIRONMENT
All Dixell programmable controllers use the following software as a processing environment:
¾ ISaGRAF® to process the iPRO application.
¾ VISOPROG to process the LCD graphic interface application (VISOGRAPH)
ISaGRAF® software is used worldwide and allows those with no programming experience to build
applications ranging from the simplest to the more sophisticated. The vast range of the most popular
programming languages (Structured Text, Function Block Diagram, Ladder Diagram, Instruction List,
Sequential Function Chart, Flow Chart, FBD IEC 61499) provides all programmers with access to the
processing environment. Thanks also to the extensive libraries of blocks already developed by Dixell, the
processing and debug times are reduced.
The SIMULATION (verification of the application without using the controller) and DEBUG options
(verification of the actual application within the controller), allow the user to block and force the value of the
variables to speed up the testing times.
3.1.1 Fields of application
The possibility of all-round configuration allows the Dixell iPRO programmable controller to be used for any
type of application. The same applications can be downloaded in the various models available (obviously
adapting the number of inputs and outputs).
The hardware has already been used for the following applications:
¾ Chillers and heat pumps
¾ Air treatment units
¾ Air-conditioners
¾ Roof-tops
¾ Cooling systems
¾ Energy saving management in systems
¾ Climatic chamber control
¾ Cold rooms and seasoner cabinets
3.1.2 Hardware architecture
The iPRO programmable controller is structured as follows:
• 32-bit microprocessor used to run the application
• Removable connectors (Molex) or bayonet connectors (Phoenix)
• The programme and parameters are stored in a permanent flash memory. No data is lost in case of
power failure.
• Internal web server with the Dixell website as default with the option of downloading a customised
website for reading and writing variables with synoptic creation (via HTML).
• Ethernet port.
• USB port.
• Connection to the dedicated remote LCD display.
• CANBus.
