FS-8700-21 LonWorks Manual Page 4 of 62 1 DESCRIPTION The LonWorks driver allows the FieldServer to transfer data to and from devices using LonWorks protocol. The FieldServer can emulate either a Server or Client. The FS-B4011 FieldServer is supplied with a LonWorks Card, while the FS-B2011 and FS- B30 Series FieldServers have a built-in LonWorks Interface. A Fieldbus connection is available on the FieldServer. The FS-B30 and FS-B4011 can handle up to 4096 Network Variables and t

FS-8700-21 LonWorks Manual Page 5 of 62 2.3 Clients/Servers The FieldServer functions as a Client when polling or sending updates on the LonWorks network and as a Server when being polled or receiving updates. The FieldServer can be bound to a maximum number of 15 LonWorks Nodes. The FieldServer recommended point limit is 1000 points for the FS-B2011 Series and 4096 points for the FS-B30 and FS-B4011. 2.4 Explicit/Implicit Clients can address Servers using explicit or implicit add

The screw plug supplied with the FieldServer LonWorks interface will connect the FieldServer to the FTT-10 network. The 9 pin D-connector can also be used to connect to the network (FS-B4011 only). The 2-wire twisted-pair connection to the network is polarity insensitive. The FTT-10 network is a free topology network which supports star, loop and

On FS-B2011 and FS-B4011 FieldServers it is possible to print the Neuron ID on the Error Screen at any time by pushing the Service Button on the side of the FieldServer. On all platforms, the driver can store the Neuron ID in a Data Array so that it can be read by a Client node – Refer also to Appendix C.3. 4.3 Lon LED’s The location of the Lon LED vari

For hints and tips on how to commission the FieldServer using the various Vendor devices that do this, see Appendix B It is possible to set the FieldServer Online and Offline using the Network Management Tools. This is a LonWorks

All the Servers and their Clients need to be on the same domain to be able to communicate. If the LonWorks device’s Node ID is not known, it may be read using a utility program e.g. NodeUtil or using a LonWorks Analyzer. All the Cl

FS-8700-21 LonWorks Manual Page 15 of 62 6.1.4 Domain Table Setup To be able to communicate with other nodes on the LonWorks network, the FieldServer must have its Domain, Subnet and Node ID’s set. Explicit configuration requires the user to set these parameters. There are 3 ways in which the FieldServer DSN (Domain,Subnet,Node address) can be set: Set the DSN using a Network manager by commissioning the FieldServer into the Network Manager Project. When doing it this way, it is

The Neuron ID is the 12 Digit Hex identifier of the associated LonWorks Device. An example configuration follows. Note that Neuron ID addressing is considered explicit addressing so the station address, domain ID and subnet ID must be set as described in Sectio
