Introduction to the LUFP7 Gateway 1 Introduction to the LUFP7 Gateway Overview The LUFP7 gateway allows a master located on a Profibus-DP network to communicate with slaves on a Modbus RTU network. This is a generic protocol converter operating in a way which is transparent to the user. This gateway allows the user to interface many products marketed by Schneider Electric with a Profibus-DP network. These include TeSys U motor starters, Altivar driver and the XPS-MC Safety Controllers.

Powersupply 24 V= 2. Configuration 3.
Hardware Configuration Examples Parts used The connection between Premium and gateway requires the following parts: l Cable: TSX PB SCA 100 l NAD 911 04 used to join between slaves (i.e. not at the end of line, therefor no line termination). l NAD 911 03 used at the end of the line, therefor requires line termination. Profibus Connector NAD 911 0x 02/2005 1 Incoming A cable. 2 Outgoing A cable (absent in the case of the 490 NAD 911 03 connector).
Hardware Configuration Examples Example With Multiple XPS-MC Safety Controllers or Other Modbus Slaves General The connection between the Premium and the gateway will always be the same, as shown here.
Hardware Configuration Examples Using Bus topology with VW3 A8 306 TF3 drop boxes VW3 A8 306 TF3 drop boxes Line termination Line termination Line terminator 02/2005 For the previous networks shown, the following line terminator is always needed for terminating the line: VW3 A8 306 RC 13
Hardware Configuration Examples Using Bus topology with tap boxes This topology is similar to the previous one, except that it uses TSXSCA62 subscriber connectors and/or TSXCA50 subscriber connectors. We recommend using a VW3 A8 306 connection cable and the TSXCSA•00 Modbus cables. Connect the RJ45 connector on the VW3 A8 306 cable to the Modbus connector on the LUFP7 gateway.
