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
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
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
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
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.
