1. Introduction 1.2. Introduction to the LUFP7 Gateway The LUFP7 gateway allows a master located on a Profibus-DP network to enter into a dialogue with the 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 you to interface many products marketed by Schneider Electric with a Profibus-DP network. These include TeSys U motor starters, Altivar drivers and Altistart soft start- soft stop units. 1.3. Terminolog

1. Introduction 1.4. Notational Conventions 16#••••...............Value expressed in hexadecimal, which is equivalent to the H••••, ••••h and 0x•••• notations, sometimes used in other documents. N.B. The AbcConf softwre uses the 0x•••• notation. e.g. 16#0100 = 0x0100 = 256. 02#•••• ••••.........Value expressed in binary. The number of ‘•’ digits depends on the size of the item of data represented. Each nibble (group of 4 bits) is separated from the other nibbles by a space. Examples: byte 2#0010

1. Introduction Each LUFP7 Profibus-DP / Modbus RTU gateway allows one of the PLCs on the Profibus-DP network to command, control and configure up to 8 Modbus slaves. Other Profibus-DP masters on that same network can only control them. If there are more than 8 Modbus slaves, you will need to use an appropriate number of LUFP7 gateways. In the same way, if the exchanges with the Modbus slaves require more than 25 Modbus commands (that is to say more than 50 queries and responses), you will have

1. Introduction Each LUFP7 gateway is shipped pre-configured so as to make it easier to operate and the factory settings can be used as a basis for a configuration which will best meet the user’s expectations. The typical operations applicable to this default configuration are described in chapter 6 Configuring the Gateway, page 44. The Profibus-DP network is totally separate from the Modbus network. The frames on a network are not directly “translated” by the gateway to generate frames on the

2. Hardware Implementation of the LUFP7 Gateway 2.5. Connecting the Gateway to the Modbus Network Three typical examples of Modbus connection for the gateway and its slaves are shown below. There are many other possible Modbus connections, but they are not covered in this document. 2.5.1. Examples of Modbus Connection Topologies • “Star” topology: This topology uses LU9GC03 Modbus hubs, which have 8 female RJ45 connectors. These hubs should be placed close to the Modbus slaves to which they are

2. Hardware Implementation of the LUFP7 Gateway • “Bus” topology with VW3 A8 306 TF3 drop boxes: This topology uses VW3 A8 306 TF3 drop boxes to connect each of the Modbus slaves to the main section of the Modbus network. Each box should be placed in the immediate vicinity of the Modbus slave it is associated with. The cable for the main section of the Modbus network must have male RJ45 connectors (like the VW3 A8 306 R•• cable used for the “star” topology). The lead between the drop box and the

2. Hardware Implementation of the LUFP7 Gateway • “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 A68 306 connection cable and the TSXCSA•00 Modbus cables. Connect the RJ45 connector on the VW3 A68 306 cable to the Modbus connector on the LUFP7 gateway. The connections are shown below: VW3 A68 306 TSXSCA62 Modbus LUFP7 Gateway TSXCSA•00 2.5.2. Pin Outs In

2. Hardware Implementation of the LUFP7 Gateway 2.6.2. Wiring Recommendations for the Profibus-DP Network • Use a shielded cable with a twisted pair of copper conductors, preferably a type A Profibus-DP cable. • Connect the reference potentials to one another, • You may choose the transmission rate, within limits ranging from 9.6 kbit/s to 12 Mbit/s. The choice is made at network startup and applies to all network subscribers. • The maximum length of the line (segment) is inversely proportiona
