QMCS - QUAD MILL CONTROL SYSTEM  

New speed control concept for rolling of long products  

A PLC based rolling mill speed control system provides high performance mill set-up and control functions for the processing of long products in a continuous rolling mill. The QMCS (Quad Mill Control System) is supplied complete with a real time PC based simulator for preliminary mill tune-up and operator training.  Powerful Windows NT based HMI screens, with built in help menus, help the operator to be more effective in getting more tonnage out of the mill.

Technical details:                                         

The basic system includes the following:

1. Quantum (Modicon) PLC including the IEC1131 programming software with  extensive use of engineered function blocks and online documentation.

2.Windows NT workstation and dual screen displays for setup, control, monitoring and maintenance. The system is designed to control mill stands via any of the popular networks or through hardwired I/O's, (including Profibus^(R), Modbus Plus^(R), Devicenet^(R), Interbus-S^(R)).

When installed in an older mill, QMCS can be interfaced to analog drives. 

Options:

• Pulpits and operator consoles

• Control of auxiliary systems

• Loop scanners and HMD's

• System installation

• Seamless transfer from existing system

• QMOS - Quad Mill Operating System (MRP software)
