Schneider Electric LUFP7 user manual Inputs

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).
