Schneider Electric LUFP9 user manual Type Value 16#04 Get / Set Produced connection ID, #0 xx

10. Appendix D: DeviceNet Objects

ID	Access	Name	Need	Type	Value
16#04	Get / Set	Produced connection ID	Required	UINT	2#0•• ••xx xxxx

The value of this attribute is placed in the CAN protocol’s Identifier Field when the connection goes into transmission mode (group 1 messages). The term “xx xxxx” represents the 6 bits of the address of the gateway’s DeviceNet node. The term “•• ••” represents the message ID.

E.g. 16#034A = 2#011 0100 1010 (group 1 messages; ID of the messages = 13; Gateway located at address 10).

16#05

Get / Set Consumed connection ID Required UINT 2#10x xxxx x•••

The value of this attribute corresponds to the content of the CAN protocol’s Identifier Field for the messages the connection should receive (group 2 messages). The term “x xxxx x” represents the 6 bits of the address of the DeviceNet node. The term “• ••” represents the message ID.

E.g. 16#0452 = 2#100 0101 0010 (group 2 messages; ID of the messages = 2; Gateway located at address 10).

16#06

Get / Set Initial comm. characteristics Required BYTE 16#01

This attribute defines the Group or Groups of Messages by which the productions and consumptions associated with the “Change-of-State / Cyclic (Acknowledged) Connection” object are carried out. In this case, it designates groups 1 and 2. Please see chapters 3-2. et 5-4.3.6. of volume I of the DeviceNet specifications for further details on this subject.

16#07

Get / Set Produced connection size Required UINT (size of the input area)

Maximum number of bytes which can be transmitted via this instance’s connection. The value of this attribute should be set to the size of the input area choosed using attribute 16#0E. With the LUFP9 gateway’s default configuration, the value of this attribute is set to 0, as no input area is assigned to the “Change-of-State / Cyclic (Acknowledged) Connection” object.

16#08

Get / Set Consumed connection size Required UINT 0

Maximum number of bytes which can be received via this instance’s connection. As the LUFP9 gateway does not consume any data via this connection, the value of this attribute will remains set to 0.

16#09

Get / Set	Expected packet rate	Required	UINT	0 (unit = 1 ms,
				per 10 ms step)

This attribute defines the periodicity of the exchanges made via the connections of this instance.

16#0C

Get / Set Watchdog timeout action Required USINT 0

This attribute defines the action taken when the watchdog timer is triggered or when the connection is inactive. The various possible values are as follows: 0 (Transition to timed out), 1 (Auto Delete), 2 (Auto Reset) et 3 (Deferred Delete).

16#0D

Get / Set Produced connection path length Required UINT 0

Size of the USINT array of attribute 16#0E (produced connection path).

16#0E

Get / Set Produced connection path Required USINT […] (area path)

This attribute defines the local path (without MAC ID) of the gateway’s DeviceNet object used to produce the connection’s data. In the case of the current instance, the production path for the “Change-of-State / Cyclic (Acknowledged) Connection” corresponds to the output area assigned to this connection using the “COS production” EDS parameter.

16#0F

Get / Set Consumed connection path length Required UINT 4

Size of the USINT array of attribute 16#10 (consumed connection path).

16#10

Get / Set Consumed connection path Required USINT […] (area path)

This attribute defines the local path (without MAC ID) of the gateway’s DeviceNet object used to receive the data consumed by the connection. In the case of the current instance, the consumption path for the “Change-of-State / Cyclic (Acknowledged) Connection” designates instance 16#01 of class 16#2B, that is to say the only object of the “Acknowledge Handler Object” class.

N.B. The EDS file supplied with the gateway does not contain any parameter whose modification would have had any influence on the value of this attribute.
