Unique architecture
The XIO module is a multiple input/output controller used in our automation and control systems. This module is characterized by its unique architecture, compactness, and robustness and uses a TCP/IP communication protocol over an Ethernet link. The XIO module is equipped with logic input and outputs, analog and frequency input-outputs, each type in a calculated proportion that just one type of module is needed to control an asphalt plant. Thus, a small application requires one or two XIOs. Additional XIOs, identical to the first one, can be added to increase the number of input-outputs to increase capacity. A very large plant with comprehensive automation can require six XIOs or more.
The advantages of this architecture are numerous:
- Only one module is needed as a spare part
- Guaranteed flexibility and extensibility
- Simplified systematic wiring
- Support and maintenance facilitated
- Inherent generation of spare inputs and outputs
Comparison With Traditional Architecture
In a traditional installation using a field network, electronic modules ensure the input-outputs are specialized according to the type of signals: logic inputs, logic outputs, analog inputs, analog outputs, etc. This architecture multiplies the number and types of electronic modules (refer to Classical Architecture). With the XIO, only one standard device is necessary, with all input-output types onboard (refer to XIO Architecture). When the number of input-outputs is very important, the cost of the two solutions is similar. Still, on small and average installations, in an example of road construction plants, the architecture of XIO reduces costs and becomes more profitable. In all cases, spare parts management is much easier with the XIO architecture.

The board has two buses. The first is for CPU bus extensions, where you can add a peripheral card like USB, touch screen monitor, mouse, RS-485, etc.
The second bus is an SPI type and has the ability to connect two external cards, providing two (2) analog outputs and four (4) analog inputs each. The electrical characteristics of those modules are the same as the ones on the motherboard.
