RTU

The MultiSmart Pump Station Manager is the new face of technology, combining the functionality of an RTU, PLC, pump controller, control panel components and a user interface. This makes MultiSmart a very powerful product with the highest level of functionality in existance today. The MultiSmart Pump Station Manager is ideal for water and wastewater Lift Stations or Pump Stations.

Additionally, the MultiSmart can be purchased just as an RTU. Physically, the product is packaged the same way - an I/O unit which includes a host processor and communications board, a DSP board for processing I/O at high speed, I/O cards and a display.

RTU I/O

MultiSmart's I/O design makes it an ideal water or wastewater RTU.

A standard RTU usually has contact closure digital inputs (DINs). The DINs in the MultiSmart RTU can be configured as contact closures or high speed counters.  In addition, they can be configured to directly measure:

• Conductive level sensors
• Seal sensors
• PTC thermistors
• Flygt FLS and CLS sensors

This reduces control panel cost and complexity.

The MultiSmart RTU I/O also measures 3-phase voltage (direct phase to phase up to 600v) and 3-phase currents (direct from 5A CTs). Because of the high speed DSP processor (a separate processor is used for the communications and application program), voltage and current measurements are used to accurately calculate:

• Power, KW
• Power factor
• Apparent power, KVA
• Energy, KWHr
• Apparent energy, KVAH

The MultiSmart RTU also includes standard 4-20mA AINs, 4-20mA AOUTs, DOUTs and configurable DINs.

DNP3 & MODBUS Communications

The MultiSmart includes two open protocols - Modbus and DNP3.

DNP3 is an ideal protocol for remote telemetry. MODBUS is an ideal protocol for communicating with other intelligent control panel components (e.g. a VFD or a soft starter).

The MultiSmart RTU is powerful and flexible, allowing multiple Masters and Slaves to be configured. For example, in a radio communications network where some sites are not able to communicate directly with a repeater, they might communicate through another RTU. That RTU would have a Master (to talk to the station with comms problems) and a Slave (to talk to the SCADA system).

To learn more about the MultiSmart Pump Station Manager's capabilities as a water or wastewater RTU, go to MultiSmart and view the I/O Specifications. 

Full Lift Station Control

The MultiSmart Pump Station Manager incorporates 100s of Lift Station functions and has an intuitive user-interface.

Commissioning a new station requires no programming, although there is an optional IEC61131-3 PLC enhancement if special features are required.
