Industrial controller
July 1st 2007

Building projects for the London Olympics are driving demand for aggregates through the roof, dredger captains need to discharge their cargos efficiently so that they can get back out to sea without missing a tide. Remote diagnostics developed by Barwits Control Systems for United Marine Dredging (UMD) are helping with this Olympian effort.

The whole control system, which extends throughout the full length of the ship is based on a single Mitsubishi Q series PLC (programmable logic controller).The Q is designed to offer a high level redundancy for system-critical applications and uses dual CPUs, power supplies and bases. It combines out of the box system building using standard components with customisation by parameter setting. It is configured for total data tracking and extensive physical redundancy so that high system availability can be guaranteed.Configured with the Q on the dredger system over a remote i/o network are three Mitsubishi E1151 HMIs (human machine interfaces) and a GPRS remote communications unit.
