Terminology 4-20mA –Industrial method of transferring data from a remote sensor in the facility to a local control room, PLC, DCS or any other device that can convert the current signal (between 4mA to 20mA) to a conventional number –With the 3DLevelScanner, the 4-20mA output represents the material volume in percentage –mA stands for milliamperes HART –Data communication method that uses the existing 4-20mA lines to communicate with remote devices May 2011APM Annual International Partners Conference29

30. Terminology TCP / IP –TCP stands for Transmission Control Protocol, one of the most common protocols in use in the world of digital data and in particular in the Internet –IP stands for Internet Protocol The use of the above two abbreviations defines the communication between any two devices, this type of communication ensures that the transmitted data arrives completely to the other party IP Address –A fixed or dynamic address assigned to any devices connected on the LAN May 2011APM Annual International Partners Conference30

31. Terminology MAC Address –Also refer to as Physical address, each device connected to an Ethernet network has a unique physical address that cannot be changed Subnet Mask –In a local area network, the subnet mask defines the span of IP addresses that are in use, usually the subnet mask is: 255.255.255.0 Gateway –Is the IP address of the Router assigning the IP addresses in the LAN May 2011APM Annual International Partners Conference31
