Non-ferrous Thickness gauging control unit - PMGA12

The Millmate Thickness Gauging System is an intelligent measurement system and measures as accurately in the production process as in the laboratory.

PMGA12* control unit overview

The Control unit is used for integration with superior systems to enable automatic operation. For system integration there is a choice of integration interfaces:

 

  • Profibus DP fieldbus communication
  • Network communication via OPC
  • Discrete I/O-signals

The Control unit also handles communication with the gauge for measurement data, state control and error handling as well as implements vertical and horizontal automatic position control functions.
There are Control unit versions for one or two gauges and with wall or floor cabinets.

Non-ferrous thickness gauge applications

The Millmate Thickness Gauge System can easily be connected to AGC systems, based on feedback, feedforward and mass flow control.

 

Network communication

OPC (www.opcfoundation.org) can be used as an alternative to I/O-signals for integration. The system supports OPC 2.0 Data Subscription over an optional Ethernet local network. To gain access to measurement data and system set-up, a superior computer with OPC-client functionality can communicate with an OPC-server in the operator unit.

 

Profibus-DP

As an option, the MTG system can be equipped with a Profibus-DP slave interface for communicating with e.g. the rolling mill control system. The Profibus-DP interface provides fast transfer of measurement data. It can also be used for setting up nominal thickness and for remote control of system settings and gauge movement.

 

Single or Double gauge system

In reversing mills it is very common to use non-ferrous thickness gauges on both sides of the mill. The MTG system offers two different contol units, one for handling a single gauge and the other for handling two gauges. The user-friendly operator unit has a display function for double gauge configuration. The operator can see the thickness gauge deviation graphs, one for each gauge, on the same menu page. The feature with double gauge systems can also be valuable in applications like tandem mills or slitting lines.

Cyber Security

ABB provides the defense-in-depth security required for digital solutions in mission-critical applications and industries.
A common standard is applied for all ABB products and system with rigorous testing performed by specialists.

HMI based on Windows 10 IoT

  • Active firewall configured to block all incoming connections 
  • Hard drive locked down for writing, a reboot resets the HMI
  • User preferred malware protection to be added 
  • Periodic Windows patch packets service – tested with application software 

Controller based on Windows 7 Embedded Compact

  • WEC7 is a real-time OS - normal Windows program cannot be executed
  • Much less vulnerable
  • External communication designed as a normal Firewall
  • Only 2 available ports for defined external interfaces:
    1. Modbus/TCP and OPC DA
    2. VIP/TCP
