5.3.Server Side Node Descriptors

| Nodes |
|

|
|
| Column Title | Function |
| Legal Values |
|
| Node_Name | Provide name for Node |
| Up to 32 alphanumeric |
|
|
| characters |
| ||
|
|
|
|
| |
|
| DataPort station address of physical Server Node. |
|
| |
|
| These correspond to the ‘devices’ configured in the |
|
| |
|
| DTPConfig. Thus the Node_ID is not the address of |
|
| |
| Node_ID | the final CCN device. |
|
| |
|
| The DataPort DTPConfig table maps a device |
|
| |
|
| number (1...15) to a bus number |
|
| |
|
| Node_ID to tell the driver which device to use. |
|
| |
| Protocol | Specify protocol used |

|
| FAN1 , | 1 , | CarrierDP, | P8 |

4Not all ports shown are necessarily supported by the hardware. Consult the appropriate Instruction
manual for details of the ports available on specific hardware.
5 It is common to leave server nodes unconnected to a port. This means that the FieldServer can respond with the Node’s data irrespective of which port the request is received on.
