10. Appendix D: DeviceNet Objects
ID | Access | Name | Need | Type | Value |
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 “Bit Strobed Command/Response Connection” object. Maximum size = 8 bytes.
16#08
Get / Set | Consumed connection size | Required | UINT | (size of the output area) |
The value of this attribute is not significant in the case of the “Bit Strobed Command/Response Connection” object. This value is set to 8.
N.B. When you configure the “Strobed” connection under RsNetWorx, use a null size output area (“Output2” to “Output6”) if you do not check the box located after “Use Tx Bit:”, or a
16#09
Get / Set | Expected packet rate | Required | UINT | 80 (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 “Bit Strobed Command/Response Connection” corresponds to the input area assigned to the “Polled Command/Response Connection” using the “Strobed production” EDS parameter.
16#0F
Get / Set | Consumed connection path length | Required | UINT | 0 |
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 “Bit Strobed Command/Response Connection” corresponds to the output area assigned to this connection using the “Strobed consumption” EDS parameter.
Attributes of instance 16#04 of class 16#05:
ID | Access | Name | Need | Type | Value |
16#01 | Get | State | Required | USINT | 0 to 4 |
This attribute represents the status of the
16#02
Get | Instance type | Required | USINT | 1 |
This attribute defines the instance’s connection type: Messaging connection (0) or I/O connection (1).
16#03
Get / Set | Transport class trigger | Required | BYTE | 16#12 or 16#02 |
This attribute defines the behaviour of the connection. In the case of the LUFP9 gateway’s
Bits | Transport Class = Class 2. |
