SMC TCP/IP Description  
The SMC TCP/IP driver allows the FieldServer to transfer data to and from other FieldServers  
over Ethernet using SMC TCP/IP protocol. The FieldServer can emulate either a Server or  
Client.  
The SMC TCP/IP driver can be used for inter-bridge (FieldServer to FieldServer)  
communications to perform tasks like mirroring data arrays between FieldServers.  
Max Nodes Supported

Configuring the FieldServer as a SMC TCP/IP Client  
For a detailed discussion on FieldServer configuration, please refer to the FieldServer  
Configuration Manual. The information that follows describes how to expand upon the factory  
defaults provided in the configuration files included with the FieldServer (See “.csv” sample files  
provided with the FieldServer).  
This section documents and describes the parameters necessary for configuring the FieldServer  
to communicate with a SMC TCP/IP Server.  
4.1.  
Data Arrays/Descriptors  
The configuration file tells the FieldServer about its interfaces, and the routing of data  
required. In order to enable the FieldServer for SMC TCP/IP communications, the driver  
independent FieldServer buffers need to be declared in the “Data Arrays” section, the  
destination device addresses need to be declared in the “Client Side Nodes” section, and  
the data required from the servers needs to be mapped in the “Client Side Map Descriptors”  
section. Details on how to do this can be found below.  
Note that in the tables, * indicates an optional parameter, with the bold legal value being the  
default.  
Section Title

Array can only take on one format.  
Data_Array_Format  
Data_Array_Length  
Swapped_Byte

larger than the data storage area  
required by the Map Descriptors for  
the data being placed in this array.
