Our customer had a SCADA system in place that monitored the boilers and the gas detection system. However, an excessive amount of time was spent collecting data from remote chart recorders and indicators.

The Iconics SCADA system was expanded four-fold in order to bring in many remote parts of the plant. Twenty-five new stainless steel enclosures were installed— each being connected back to the control

Our customer’s previous system covered only half the plant and did not provide any reporting or reliable alarming. The operators never used the system because of communication failures and unreliable data.

The system NSI designed was entirely Ethernet based, but used copper, fiber, and wireless to reach all areas. Cyber security was designed into the system with whitelisting and MAC address filtering along with a firewall performing deep packet inspection. Different remote I/O racks, multi-loop controllers, PAC’s and OIT’s were used to bring in the 400 new I/O points— all using either Modbus RTU or Modbus TCP.
