These applications may include devices such as limit switches,
32、 proximity sensors, electro-pneumatic valves, relays, motor starters, operator interface panels, analogue inputs, analogue outputs, and controllers. SDS provides for the connection of intelligent devices such as sensors, actuators and other components to one or more controllers. SDS functionality ma
33、y be integrated directly into the devices or be in modules allowing the connection of conventional components to the network. The SDS network consists of one or more controllers connected to up to 126 Logical Devices. In addition to the process data, SDS allows for the transmission of parameters and
34、 diagnostic data. The data exchange may be either event driven, cyclical, multicast or polled. A maximum of 6 bytes of data may be transmitted without fragmentation. Topology is typically a single trunk with short branches using a cable comprising two shielded, twisted pairs with a common earth wire
35、 all within a single jacket. Data is transmitted at rates of 125 kbit/s, 250 kbit/s, 500 kbit/s and 1Mbit/s with maximum system trunk lengths of 457 m, 182 m, 91 m and 22 m respectively. Detailed information on the performance is contained in clause 5. Figure 1 shows an example of an SDS Network. Fi
