Water industry remote control monitoring systems

Water industry remote control and monitoring systems with the Omniflex Maxiflex T2 CPUs, a remote terminal unit or programmable controller dedicated to data acquisition and telemetry applications

Water industry remote control and monitoring systems with Maxiflex remote terminal unit or programmable controller.
Omniflex has a set of Maxiflex CPUs - the T2, dedicated to data acquisition and telemetry applications.
They require no user programmes when used for data acquisition or telemetry application.
Simply plug them in; connect field wiring and power up.
All I/O is scanned automatically and I/O status assembled into Data Interchange Table (DIT).
The CPUs however can be programmed for control as well.
Other CPUs in the Maxiflex range offer IEC61131 programming with 6 languages standard and function blocks for PID suitable for dosing plant control.
The telemetry functions run automatically and independently of the control application so SCADA systems can be acquiring data whilst control application are running.
Maxiflex also supports remote programming service via IT communications networks.
The system integrates the remote pump start/stop function with motor status feedback from pumps and level statuses directly to an annunciator panel.
No more hard wiring of panel indicator lamps for stop start run indication, all this can be displayed on the annunciator via a Modbus link.
The telemetry aspect of the remote control can be implemented on copper cable (screened twisted pair - instrument cables) up to 10km from the control centre.
Radio systems can be used for wireless applications where cable infrastructure is non existent.
GSM Networks can also be utilised with short message services being used for data transmission.
Maxiflex also supports redundant applications where on larger pumping stations, pumps run redundant with the control and monitoring application also redundant for maximum availability or service.
Typical applications for Maxiflex are pump remote control, reservoir level control, pump station monitoring and control, dosing plant applications, flow meter monitoring.
Configuration is easily made using a free Windows based software package called "OmniSet" and a serial cable available from Omniflex.
Simple selection of pull down options allows the user to configure the CPU completely.
This configuration includes the ability to create multi-drop telemetry systems using the Omniflex CONET local area network up to 10km on twisted pair cable.
Maxiflex provides a very cost-effective solution to remote control applications and simplifies the field I/O systems by eliminating the need to write time consuming application programs for data acquisition or telemetry.
Should data acquisition also be required with the pump control, Maxiflex I/O systems cover analogue inputs, voltage, current, thermocouple, RTD and digital inputs, potential free and voltages up to 200Vdc, series contact chains, pulse inputs up to 50kHz.
