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.
