Schneider Electric LUFP7 user manual Outputs, General data

7. Appendix A: Technical Characteristics

Structure of the LUFP7	• 2 bytes for the activation or inhibition of 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 output data (see
Outputs	chapter chapitre 10.2.2 Output Data Memory Area, page 96, for default use of
	these output data).
	• 268 output bytes inaccessible by the Profibus-DP master due to the maximum
	number of output bytes that can be exchanged with the gateway (see
	chapter 4.2.6 Editing and Configuring the Gateway, page 29).
	Addresses	Output data area
	16#0200	Profibus-DP master control word
	16#0201	(except if “Control/Status Byte” = “Disabled”)
	16#0202	Outputs accessible by the Profibus-DP master
	16#02F3	(242 bytes)
	16#02F4	Outputs inaccessible by the Profibus-DP master
	16#03FF	(268 bytes)
Structure of the LUFP7	• 1,024 bytes inaccessible through the Profibus-DP master.
gateway’s memory:	Addresses	General data area
	16#0400	Input area reserved for the Mailboxes
	16#051F	(288 bytes)
General data	16#0520	Output area reserved for the Mailboxes
	16#063F	(288 bytes)
	16#0640	Internal area reserved for the management
	:	of the upstream network
	16#07BF	(384 bytes; area not used by the LUFP7 gateway)
	16#07C0	Internal area reserved for the control registers
	16#07FD	(62 bytes / MSB first for 16-bit data)
	16#07FE	Gateway status / Profibus-DP master control
	16#07FF	(2 bytes)
	You can use the general data area for Modbus input data (from Modbus
	responses) if you do not want the Profibus-DP master to have access to them. In
	this case, always use 16{#4000 as the starting address. If you use multiple times
	the same addresses in this area, the corresponding memory locations will be
	displayed in red in the “General Area” section of the “Sub-network Monitor”
	window (see page 55 for an example). However, this will have no consequences
	on the gateway during run-time.
Data transfer order	• Profibus-DP network: MSB first and LSB last.
(swapping)	• Modbus RTU network: MSB first and LSB last.
	• LUFP7 gateway MSB stored in the lowest memory address.
	→ In most cases, the option which should be chosen for Modbus data stored in
	the gateway’s memory is “No swapping”. This option relates to all “Data” fields
	for Modbus queries and responses frames.
