1.SDD16 Description
The SDD16 driver allows the FieldServer to transfer data to and from devices over
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.
