Schneider Electric LUFP9 user manual Inputs, Input data area

7. Appendix A: Technical Characteristics

Specific DeviceNet	• The LUFP9 gateway is a “group two only server” DeviceNet subscriber (cf.
features of the LUFP9	DeviceNet Specifications).
gateway	• Fragmentation support for transactions requiring more than 8 bytes of data.
	• Connections supported:			1 “Explicit Connection”
				1 “Polled Command/Response” connection
				1 “Bit Strobed Command/Response” connection
				1 “Change-of-State / Cyclic” connection
	• Communication speed configured using 2 selector switches.
	• Gateway’s DeviceNet address (Mac ID) configured using 6 selector switches
	(address between 0 and 63).
	• Configuration facilitated by the use of a specific EDS file.
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 drives 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 LUFP9	• 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	• 2 bytes for the diagnostics of errors on the downstream network by the gateway
LUFP9 gateway’s memory:	(see chapter 5 Gateway Initialization and Diagnostics, page 33).
	• 510 bytes accessible by the DeviceNet master in the form of input data (see
Inputs	chapter 8.2.1	Input	Data	Memory	Area,	page 84, for the		default use of	this
	input data).
