1. SDD16 Description
The SDD16 driver allows the FieldServer to transfer data to and from devices over RS-485
using SDD16 protocol. The FieldServer can only emulate a Client.
The SDD16 driver is used to communicate with a digital I/O module model 485SDD16. The
current driver only supports reading the status of all sixteen digital input lines. The SDD16
driver in conjunction with the 485SDD16 module allows the FieldServer to sense external
On/Off conditions and to control a variety of devices.
The SDD16 driver makes use of the data complement mode feature of the 485SDD16 module.
In data complement mode the driver and module communicates with double the amount of data
bytes to enable better error detection in noisy electrical environments.

3. Hardware Connections
The FieldServer is connected to the RS-485 SDD16 module as shown below.
Configure the RS-485 SDD16 module according to manufacturer’s instructions. Note that the
module auto-detects valid baud rates as defined in the client side connections.

4. Configuring the FieldServer as a SDD16 Client
For a detailed discussion on FieldServer configuration, please refer to the configuration manual
for the FieldServer. 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 SDD16 Server.
The configuration file tells the FieldServer about its interfaces, and the routing of data required.
In order to enable the FieldServer for SDD16 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.
4.1. Data Arrays
Section Title
Data_Arrays
Column Title Function Legal Values
Data_Array_Name Provide name for Data Array Up to 15 alphanumeric
characters
Data_Format Provide data format. Each data array
can only take on one format.

Packed_Byte,
Swapped_Byte
Data_Array_Length
Number of Data Objects. Must be
larger than the data storage area
required for the data being placed in
this array.
