1. 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

FieldServer Mode Nodes Comments

Inter-bridge Communications to a virtually unlimited number

Client N/A

of FieldServers. Memory limitations may apply when a

large number of Nodes are used.

4. 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

Data_Arrays

Column Title Function Legal Values

Data_Array_Name Provide name for Data Array

Data_Array_Format

DA_DI_01, Bit, 200

DA_DO_01, Bit, 200

Provide data format. Each Data
Array can only take on one format.

Number of Data Objects. Must be
larger than the data storage area
required by the Map Descriptors for
the data being placed in this array.
