Even Refineries Run Out of Wires

When a refinery’s analytical shelter is upgraded, the number of measurements typically increases instead of decreases. It is a common experience that insufficient numbers of wires are available to send additional signals back to the BPCS or SCADA package. It is well known how expensive it is to lay new wires, especially when they transverse hazardous areas, so most facilities seek a more economical and effective alternate technology, such as Remote I/O.

Remote I/O systems, such as the Moore Industries NCS Net Concentrator System, can be mounted in or near the shelter with the signals that need to be sent to and from the SCADA being wired to the NCS I/O modules. This removes the need to send signals using the underground wiring, making that wire available for RS-485 serial communications (MODBUS RTU) back to the host, and eliminates the need for any additional wires.

Naturally, the installed infrastructure will vary for each analytical shelter. When a facility has an Ethernet network already installed that can be used with the NCS which has an Ethernet connection and MODBUS/TCP protocol as standard features. It includes three independent communication ports, 2 serial and 1 Ethernet, allowing multiple systems to poll the same data.

Key attributes:

  • Wide range of I/O types and number of points
  • Ethernet connection and MODBUS/TCP protocol as standard features
  • Suitable for Class I Div 2/Zone 2 environments and -40 to 85C ambient operating environment
