CC-Link has played a role in the refurbishment of a large overhead crane at the EMZ foundry in Enakievo, Donetsk, Ukraine, improving productivity and making significant energy savings.

CC-Link is an open-field device-level network that provides high-speed deterministic communications, linking a range of automation technologies over a single cable.

It is ideal for machine, cell or process control in manufacturing and production industries, and is rugged and reliable in demanding heavy industrial environments, such as foundries, steel plants and quarries.

The decision was made to fulfil all the processing requirements through a single Mitsubishi Q-series PLC and to provide operator information through one main and two secondary HMIs.

The final part of the system was a regenerative power converter.

This would enable the crane to harvest and store electrical energy that would normally be part of the system losses.

All these field devices are connected individually onto the CC-Link link network, with no need for complicated interfacing, meaning that devices can be swapped out at will for maintenance, upgrade, replacement or repair.

CSC and EMZ have completed a post-installation review and noted that the crane operators have adapted to the new regime and are reporting better operation, with errors and accidents down by over 80 per cent.

Movements are also said to be smoother, reducing wear and tear of the mechanical components.
