As a result, the PLC code can be written before the physical wiring locations of the controller or the I/O are known, as it is quick and easy to add to an existing tag an alias that defines its connection later. The CompactLogix tag database also allows the use of aliases to simplify the definition of tag names for I/O locations. System developer to produce programs and addresses with logical names that will be easily understood by another engineer. This removes any maximum limit on the number of addresses available and enables the

When programming with RSLogix 5000, all tag names can be user-defined, rather than pre-determinedīy the hardware. Sections, with separate routines for alarms and the SCADA interface. To simplify maintenance and reconfiguration, the code was split into Innecto completely rewrote the existing programming code for the new controllers using Rockwell Software’s RSLogix 5000 editor. Despite its small size, the powerful processor is able to handle complex control tasks, making it ideal for small to medium-size standaloneĪpplications requiring up to 1024 I/O or part of a network of programmable controllers.ĪCompactLogix controller and five 1769 I/O modules provide all the processing power needed to control each pump set at the Streatham pumping station, while occupying a fraction of the space taken by the legacy controllers they replaced. This means modules are only added as needed and the panel space required is kept to a minimum. A feature of CompactLogix that makes it well suited to control system upgrades is its compact, chassisless design. The five new controllers and associated Allen-Bradley 1769 I/O modules were easily installed in the existing control panels with only minor changes to the wiring. “After reviewing the available options, Thames Water selected Rockwell Automation as one of its preferred controls suppliers, because it is able to provide a complete range of proven, reliable and well supported hardware,” says Trevor Stewart, a director of Innecto. The existing controllers and I/O racks were 15 years old and support and spares were getting more difficult to obtain, so the decision was taken to replace the control hardware with state-of-the-art Allen-Bradley equipment. Local control of each pump is also provided by pushbuttons on the front of the control panels. The station pumps and valves are remotely monitored and controlled around the clock from a remoteĬontrol centre using an existing SCADA system running on a rackbased CPU linked to the programmable controllers by interface modules. By running the appropriate number of pumps the station maintains pressure in the main in response to varying demand and diverts surplus water to storage at times of low consumption.

The Streatham station has two 395kW pumps, two 465kW pumps and one 680kW pump linked via a series of six electrically operated valves to the water main and the nearby Norwood reservoir. Following the successful completion of this installation, similar systemsĪre to be installed at the shafts at Brixton and Battersea. One of Thames Water’s approved systems integrators, Innecto Projects Ltd of Farnham in Surrey, secured the contract to replace controls at the Streatham Shaft pumping station with a new system based on Allen-īradley CompactLogix controllers. Shaft pumping station that supplies water to the network of mains running below the streets of South London.
