7. Appendix A: Technical Characteristics

Profibus-DP LUFP7

Profibus-DP address configured using 2 coding wheels (address between 1 and

gateway specifics

99); address 0 is not allowed.

(cont'd)

Profibus-DP diagnostics service: Yes (standard 6-byte diagnostic).

 

• "Resetting to zero" operating mode (input reading and output resetting to zero)

 

not supported.

 

 

 

 

• Input synchronisation (Freeze-Mode) and output synchronisation (Sync-Mode)

 

supported.

 

 

 

 

• Gateway address allocated by a master: Service not supported.

 

• Configuration conducted using a specific GSD file.

 

DP-V1 extensions not supported (transmission of non-cyclical data).

 

• Galvanic gateway insulation from the network; D(A) and D(B) signal insulation

 

using opto-couplers.

 

 

 

Modbus RTU

• Physical media: RS485 serial link

characteristics

• Network topology: Multipoint linear topology with adapted line terminations

 

(impedance of 120 Ω in parallel with a capacity of 1 nF)

 

• Communication speed: 1,200 to 57,600 kbits/s

 

• Data bits: 8

 

 

 

 

• Subscriber addresses:

1 to 247. Address 0 reserved for broadcasting.

 

Addresses 65, 126 and 127 reserved if drivers and/or starters from Schneider

 

Electric are used on the same Modbus network.

 

• Period of silence: Equivalent to the transmission of 3.5 characters.

Specific Modbus RTU

• Maximum number of subscribers (excluding gateway): 8 Modbus slaves.

features of the LUFP7

• Maximum number of commands configured: Up to 50 Modbus queries and

gateway

responses configured for the same gateway using AbcConf.

 

• Communication speed: 1,200, 2,400, 4,800, 9,600, or 19,200 bits/s, configured

 

using AbcConf.

 

 

 

 

• Period of silence: Possibility of increasing the gateway’s period of silence, in

 

10 ms steps, using AbcConf.

 

• Parity: None, even or uneven, configured using AbcConf.

 

• Start bits: 1 bit, configuration using AbcConf.

 

• Stop bits: 1 or 2 bits, configuration using AbcConf.

Structure of the LUFP7

• 2 bytes for the diagnostics of errors on the downstream network by the gateway

gateway’s memory:

(see chapter 5 Gateway Initialization and Diagnostics, page 37).

 

• 242 bytes accessible by

the Profibus-DP master in the form of input data (see

Inputs

chapter 10.2.1 Input Data Memory Area, page 95, for default use of these input data).

 

• 268 input bytes inaccessible by the Profibus-DP master due to the maximum

 

number of input bytes that can be exchanged with the gateway (see chapter 4.2.6

 

Editing and Configuring the Gateway, page 29).
