Elite PLC and Elite 200/500

The DiaLog Elite is a flexible and powerful solution for monitoring the critical operations of a small or large plant with PLCs or SCADA systems.

The Elite PLC and Elite 200 are designed to interface directly to PLCs and SCADA systems via a simple serial connection cable. The Elite PLC offers a combination of physical I/O and Modbus RTU communication totaling up to 72 monitored/controlled points. The Elite 200/500 only supports communication over Modbus RTU for 200 or 500 monitored/controlled points.

Both units operate as Modbus Masters to read values from PLCs or from SCADA systems. In addition, each supports being a Modbus Slave to a SCADA system.

The Elite PLC and Elite 200/500 provide a local user interface to view/change conditions monitored and controlled by the PLC. The Elites can automatically compute and log the pump run-times and cycles as well as totalized flow. This information can be viewed locally or retrieved remotely via phone, via modem connection from a PC or even directly to the Internet.

Typical conditions that are monitored and provide alarm notification:

  • High alarm from either a float or a level sensors
  • Pump failure indicated by each motor starter failures, over temperature or seal failure
  • Loss of power
  • Amperage to each motor
  • VFD failures
  • Bar screen motor, settling tank pump, and effluent pump failures
  • Personnel access to station - when on-site and total time on-site
  • Intrusion
  • Communication between the PLC or SCADA and the Elite

Typical conditions that are monitored and reported for information purposes only:

  • Run-times and run cycles for 2-16 pumps
  • Tank levels are continually logged to provide a profile of station activity
  • Log and retrieve daily pump cycles and run-times for weeks
