Function of the Local Area Network


TCP/IP

Optionally on one PC

Due to its superior communication communication capabilities, the MFX_4 System is very flexible when communicating with the field and remotely. Remote maintenance via the internet or SCADA system becomes a standard feature.

The MFX _4 system communicates to SCADA and Terminal Automation systems [TAS] via TCP/IP on a Local Area Network [LAN]. The SCADA or Automation System does not need to know the proprietary proprietary communication protocols protocols of the MFX _4. It interfaces with the OPC Server on the LAN.

TAS/SCADA

TCP/IP

It can thus read and write data in the tables of the OPC–Server which can be installed on the same machine as the automation system, or can be accessed via the LAN from another machine. [See page 18: „Communication between MFX_4 and Te Terminal rminal Automation“] Alternatively, Alternatively, the MFX _4 can communicate with the SCADA or Automation System in a more traditional manner via RS232 or RS 485 serial communication.

MFX_4 Flowcomputer System OPC Server for MFX _ 4 The MFX_4 System can be connected to an OPC Server via TCP/IP on the LAN. The OPC Server is a program that runs on a PC, either separate separate or on the same PC as the Automation System.

instruments. Thus, the OPC technology makes communication more transparent and flexible in case of future changes to the field instrumentation.

The OPC Server makes all data from the MFX _4 Flow Computer available for other systems [like Terminal Automation or SCADA Systems] to use. The data is easily accessible to an OPC Client through read/write tables.

OPC is an international standard for field–to–Control Room communication. Many major suppliers of field instrumentation are offering OPC Servers and Clients for their products.

The OPC structure is similar to that of the Windows Explorer. Explorer. Without knowledge of the field instrument or OPC Server, the SCADA System’s OPC client can access all process data in a hierarchical hierarchical structure, as shown in the example below. In this example, the SCADA system reads the Loading Data from the MFX_4 Controller No. 1 [Meter Run No. 1]. All Loading Data is accessible by Reading/Writing from/to a table within the OPC Server.

Communication between MFX _4 and OPC Server is at high speed and ful fills all requirements for automation systems. systems. By accessing the data from tables on the OPC Server, the Automation System does not require proprietary protocol protocol drivers for the field

After loading is completed, the MFX _4 transmits the data to the OPC Server where it is made available to the TAS.

The OPC Server transmits the Preset values for the next load to the MFX _4.

The TAS reads this data from the relevant tables.

Communication between MFX _4 and Terminal Automation There are several ways to connect a Terminal Automation System [TAS] with the MFX_4. Ideally, the TAS communicates on a LAN via the OPC Server with the MFX_4. But there are also other possibilities to connect the automation level with the flow computer.

TAS peer to peer with MFX _4

The TAS can communicate directly with the MFX_4 using the serial interfaces RS 232 or RS 485. It uses M+F’s MCO1 protocol. In case of this kind of connection to the MFX _4, the TAS needs to handle handshake communication. Also, the TAS needs to be programmed programmed in such a way to handle this proprietary protocol.

In fact, the OPC Server can run on the s ame PC as the TAS. The OPC Server can communicate directly with the MFX_4 using RS 232 or RS 485. The OPC Server is linked via serial interface with the MFX_4, using the MCO1 protocol.

The OPC Server communicates with the MFX _4 using TCP/IP on the LAN. Advantage: •

TAS does not not use proprie proprietary tary protocol protocol and handshake with MFX_4 all MFX_4 data available on OPC in tables for read/write • in case of changes changes of of flow comput computers ers in the the field, no need for reprogramming of TAS communication •

Actual time interval

In a typical pipeline metering system, an MFX _4 Controller is dedicated to each meter run as well as the prover. Since the hardware functionality [like dual chronometry] of the MFX _4 Controller is standard, the same hardware can be used for the meter-dedicated meter-dedicated and prover–dedicated units.

Due to the MFX_4's direct link via TCP/IP communications, all process control functions can be handled on the LAN. This applies to the Pipeline Process Manager program and the SCADA system; all existing data from the field instrumentation can be accessed via the OPC Server for the MFX_4 System.

The Start/Stop signals from the prover are directly connected to all MFX_4 Controllers within a system, allowing the controllers to monitor the pulses from the relevant meters. meters. All other communication is directed via the CANopen Field Bus to the OPC Server located in the TCP/IP Local Area Network [LAN].

Technical Data MFX _4 Terminal

The MFX_4 Controller is the Flow Computer in the MFX_4 system. It is available in three different housing versions, although the technical specifications of the electronics are the same for all versions. The MFX_4 Controller can both be installed in the field [in hazardous or non–hazardous areas] or inside a rack in the control room.

The MFX_4 Terminal is the Human–Machine Interface [HMI] between the Flow Computer and the operator operator in the field.


It is ruggedly designed for rough field operation and offers a large graphic display which can display clearly readable characters in any languages. The Terminal’s robust keypad has large pushbuttons with a notable ‚click‘ even when used with gloves. The Terminal can also be used as a stand–alone Access Controller for security control within a terminal.
