This automation industry quiz question comes from ISA's technical training course, PLC Fundamentals for the Technical Professional (TC40) . This course focuses on the role the programmable logic controller plays in the design of a control system and how proper selection, installation and maintenance can reduce operating costs and improve performance. It provides the technical expertise necessary to install, perform routine programming and maintenance and apply proper troubleshooting and configuration techniques.
Identify the instruction symbol shown in the post image.
a) control relay coil b) output terminal energize c) timer coil d) motor coil e) none of the above
Here's the answer to the quiz question from ISA's technical training course, PLC Fundamentals for the Technical Professional (TC40) .
The symbol is used to represent the “On” or “Off” condition for a discrete output. The “output status” is a “1” if the ladder logic evaluates as true and is a “0” if the ladder logic evaluates as false. Output terminal energize is defined as follows: Turns a bit on or off. Use OTE instruction in your ladder logic to turn a bit when rung condition is evaluated as true.
The correct answer is B.
