EOLO is proposed, on choice, on two separate hardware acquisition and signal conditioning platforms:

  • NI Compact RIO (cRIO) e
  • NI Compact Field Point (cFP).

The choice between one platform and another strongly determines the characteristics and performance of the system.

The cFP platform is privileged where a high number of channels and a boosted modularity are required (ie a frequent and rapid change of acquisition modules), the requirements of compactness are not pressing, and the sampling frequencies required do not exceed 100 Hz .

On the other hand, the cRIO platform has a more attractive form factor and the ability to acquire very high-frequency data (100 kS / s), with the additional possibility of integrating a GSM / GPRS modem and a GPS receiver. It also includes a reconfigurable 3M gate FPGA in the chassis and therefore allows all the effects to develop custom hardware.

EOLO reflects the acquisition and conditioning capabilities of cFP and cRIO products, and is therefore compatible with a variety of sensors such as thermocouples, resistance thermometers, strain gauges and load cells, accelerometers.

Modules for counter inputs and digital lines are available.

The Real -Time processor of the monitoring unit is equipped with an Ethernet port and 1 (cRIO) / 4 (cFP) serial ports to allow communication via TCP / IP or serial protocols with monitoring units or (custom solutions) external instrumentation . The communication on the CAN bus, in the case of the cFP solution, is managed with the aid of an external CAN / RS-232 conversion board, specifically mounted on the cFP; for the cRIO, the CAN NI 9853 module is used with two high-speed ports.
