Today's automation industry quiz question comes from ISA's training course, Advanced Operation of Digital (Smart) Transmitters (TS17). This course offers a hands-on, working knowledge of smart field devices with an emphasis on measurement accuracy, advanced information gathering, decreased maintenance time, ease-of-configuration and calibration, and diagnostic capabilities. You will cover uses in conventional systems and improved communications when combined with digital control networks. You will also be exposed to various hand-held communicators and computer-based configuration and diagnostic software.
The term topology refers to:
a) SP50 Foundation Fieldbus protocol
b) Ethernet
c) network configurations
d) 4-20mA
e) none of the above
Here's the explanation to today's quiz from ISA's training course, Advanced Operation of Digital (Smart) Transmitters (TS17).
Network topology is the arrangement of the various elements (links, nodes, etc.) of a computer network. It is the topological structure of a network and may be depicted physically or logically. (Source: Wikipedia)
The correct answer is C.

What is the HART protocol?:
a) A communication protocol to configure intelligent alarm panels
b) A communication protocol to configure operator stations
c) A communication protocol for configuring and ranging instrument field devices
d) A communication protocol for configuring calibration equipment
e) None of the above
Here's the explanation to today's quiz from ISA's training course, Advanced Operation of Digital (Smart) Transmitters (TS17).
Developed by Rosemount Inc. to allow configuration and communication with their range of smart (digital) field instruments. The HART (Highway Addressable Remote Transducer) Protocol permits two-way communications, so instrument parameters for smart devices can be interrogated and adjusted from anywhere on the 4-20 mA loop. The communication protocol does not interfere with the 4-20 mA signal. The HART protocol is used by more smart instruments than any other digital protocol in the industry. Because of the large, global installed base of 4-20 mA systems, the HART Protocol is considered the most popular industrial protocols since it has the advantage of being able to communicate over legacy 4-20 mA analog instrumentation wiring, sharing the pair of wires used by the older system. It has a digital response time of 500ms and supports multivariable instruments.
The correct answer is C.
