FieldServer Driver - Fieldbus
LonWorks ® driver is capable of accessing the network implicitly as a bound device or explicitly with its data transfers parameters gained from the FieldServer configuration file. The FieldServer functions as a client when it is the polling device, and as a server when it is being polled.
Formal Driver Type: PCLON FTT-10
The FieldServer LonWorks driver is capable of being configured by network management packages such as LonMaker. As a minimum, a network management package is necessary to put the LonWorks FieldServer on the same domain as its communication partners, and provide a node address for the LonWorks FieldServer. In explicit addressing mode, the remaining data transfer parameters can be set up in the FieldServer LonWorks configuration file. For binding (implicit mode), a network management package is necessary to create the bindings. It is possible to place a FieldServer into a Network for explicit communications with out using a Network management device, but this requires intimate knowledge of the network in question.
The external interface file (.XIF) for the FieldServer LonWorks can be uploaded from the FieldServer for the particular application.. The FieldServer differs from most other LonWorks® devices in that its XIF file is not fixed due to varying applications. The list of points available to the network will vary depending on the other networks connected to the LonWorks FieldServer, and the requirements of the particular application. This means that the recommended procedure for obtaining the XIF file for the FieldServer is to upload it.
Several FieldServer Gateways are LonMark Certified .
