SingleNode Engineering Specification

1.  Electrical Specification

Analog I/O

  • Quantity 2, 24 bit precision analog inputs, inputs are able to sample a 4-20 mA current or voltage from 0-5 Volts,  based upon selectable configuaration register which are stored in flash memory.
  • 1 analog output for control, 14 bits precision, current or voltage configurable, able to output either a 4-20mA current or a volatage of 0-5 volts. 

Digital I/O

  • 4 digital inputs or outputs
  • When Configured as Inputs
    • Able to sample either  digial high or low
    • Able to calculate the frequency of square wave
    • Able to trigger on a change from low to high or high to low.
  • When Configured as Outputs
    • 0 to 0.7 considered low
    • 2.7 to 3.3 Volts considered high.

Communications

  • 10BaseT/100BaseT Ethernet
    • Configurable as static or dynamic addressing
    • Configurable port for data access
  • RS232
    • Configurable data transfer rate from 2400 baud to 119,200.
  • RS485 communications
    • Configurable data transfer rate from 2400 baud to 119,200.

Input Power

  • 9 to 24 volts

Data Aquisition Support

  • Real-time clock for data synchronization
  • 128 Mbytes Onboard FLASH data storage

2. Configuration

The software of the control system will have three types of registers that allow configuration of the application, in such a way that a single devices can be set up to run multiple functionalities, thereby reducing the number of spares required.  The Three Types of Configuration registers are:

System Configuration Registers

Configures communications, analog input and output, and digital input and output. For more information, please refer to the detailed System Configuration Registers section.

Peripheral Configuration Registers

Configures the peripheral ID, sampling rate, and input or output type to use for data acquisition or device control. For more information, please refer to the detailed Peripheral Configuration Registers section.

Peripheral Information Registers

Configures the properties of a connected peripheral. For more information, please refer to the detailed Peripheral Information Registers section.

3. Physical Interface Description

The command and Control system will utilize quarter-turn bayonet style connectors that allow the replacement of a module by untrained personnel.
