Glossary

 

 

RTD

resistive temperature detect. An RTD device is a temperature transducer composed

 

of conductive wire elements typically made of platinum, nickel, copper, or nickel-

 

iron. An RTD device provides a variable resistance across a specified temperature

 

range.

Rx

reception. For example, in a CAN-based network, a PDO is described as an RxPDO

 

of the device that receives it.

 

 

S

SAP

service access point. The point at which the services of one communications layer,

 

as defined by the ISO OSI reference model, is made available to the next layer.

SCADA

supervisory control and data acquisition. Typically accomplished in industrial

 

settings by means of microcomputers.

SDO

service data object. In CAN-based networks, SDO messages are used by the

 

fieldbus master to access (read/write) the object directories of network nodes.

segment

A group of interconnected I/O and power modules on an island bus. An island must

 

have at least one segment and, depending on the type of NIM used, may have as

 

many as seven segments. The first (leftmost) module in a segment needs to provide

 

logic power and island bus communications to the I/O modules on its right. In the

 

primary or basic segment, that function is filled by a NIM. In an extension segment,

 

that function is filled by an STB XBE 1200 BOS module. (An island running with a

 

basic NIM does not support extension segments.)

SELV

safety extra low voltage. A secondary circuit designed and protected so that the

 

voltage between any two accessible parts (or between one accessible part and the

 

PE terminal for Class 1 equipment) does not exceed a specified value under normal

 

conditions or under single-fault conditions.

SIM

subscriber identification module. Originally intended for authenticating users of

 

mobile communications, SIMs now have multiple applications. In Advantys STB,

 

configuration data created or modified with the Advantys configuration software can

 

be stored on a SIM and then written to the NIM’s Flash memory.

single-ended

An analog input design technique whereby a wire from each signal source is

inputs

connected to the data acquisition interface, and the difference between the signal

 

and ground is measured. Two conditions are imperative to the success of this design

 

technique—the signal source must be grounded, and the signal ground and data

 

acquisition interface ground (the PDM lead) must have the same potential.
