External connections:

• Excitation current to the load cells

• 2 or 4 analog inputs for load cell signals

• 4 analog outputs, voltage or current

• 8 digital inputs for control signals

• 8 digital outputs

• +24 V supply for external units, max 0.5 A

• Ethernet for connection to:

– other Millmate control and operator unit

– other control systems with VIP protocol

• 2 serial interfaces of type RS-232 for external displays, control, etc.

• High-speed Profibus (optional)

If 4 PFVL load cells are connected to the same control unit the nominal load is max. 14 MN for each load cell. PFVL141 and QGPR 104/102 load cells cannot be mixed in the same control unit. Analog/digital inputs and outputs are galvanically insulated as groups.

Vendor Internet Protocol (VIP)

Other control systems can send control data and monitor measurement data with TCP/IPcommunication.

The Ethernet

connection together with the Vendor Internet Protocol (VIP) is used for communication. The protocol uses configurable predefined data telegrams and the Millmate Controller 400 acts as a server. The sending procedure is cyclic and the receiving procedure reacts on incoming messages.

The PROFIBUS option

As an option the control unit can be equipped with PROFIBUS – a vendor-independent, opencommunication standard for automation in manufacturing and process control.

The Profibus interface in the Millmate Controller 400 is updated with a new complete set of measuring values every 0.3 milliseconds, 1.5 ms for QGPR 104/102.

Millmate Operator Unit 410

The Millmate Operator Unit 410 provides communication with the control unit and is designed for panel mounting.

The operator unit(s) and control unit(s) are interconnected on a common network. This common network can be a separate network for measuring objects or it can be part of a local area network (LAN).

The communication on the network is in accordance with the IEEE 802.3 standard and uses TCP/IP protocol.

Relay board PFVK 128

Fitted with four relays with one changeover function per relay

Insulation amplifier PXUB 201

The insulation amplifier can be used when improved electrical insulation is required. Selected voltage or current output.
