[lab lecture] TAC Menta and Logic Gates Overview

This set of flashcards covers key concepts from the lecture notes on TAC Menta and logic gates, assisting in the review process and exam preparation.

What is the first step to launch MENTA and create DDC according to the notes?

From the Start Menu > Schneider Electric > Menta.

What is the purpose of TAC Menta?

It is a programming tool for HVAC controllers that includes features for design, simulation, and debugging.

Which device type should be selected as the master DDC?

TAC Xenta 401.

What does the acronym DDC stand for?

Direct Digital Control.

Name the two basic types of logic gates mentioned in the notes.

AND gate and OR gate.

What is the outcome of the AND gate if both inputs are true?

The output is true (1).

What is the significance of the NOT gate?

It inverts the input signal; if the input is true (1), the output is false (0) and vice versa.

What is the output of a NOR gate when both inputs are false?

The output is true (1).

How does the NAND gate differ from the AND gate?

A NAND gate outputs false (0) only when both inputs are true (1); otherwise, it outputs true (1).

What programming feature allows TAC Menta to facilitate alarms?

Alarm blocks that define alarm situations and messages.

In TAC Menta, what is the function of the PVR block?

It represents a parameter value of the type Real.

What does a 'signal' in TAC Menta represent?

A value representing a physical or calculated magnitude varying in time.

What is the function of the Time Schedule Block in TAC Menta?

Produces an analog output representing time until the next event, indicating whether the system is on or off.

What will happen if the input signal exceeds the activation threshold in a two-position control setting?

The output changes to true (1).

What does bind to… mean in the context of TAC Menta I/O blocks?

To connect to a type of input or output.

What coding standard does the XIF-Header adhere to in TAC Menta?

LonMark standard.

What type of systems does TAC Menta support for installation?

Stand-alone installation or as part of TAC Vista.

Which versions of TAC Xenta are mentioned for application in TAC Menta?

TAC Xenta 301, 401, 411, 421A, and others.

What kind of connection is required for public variables in TAC Menta?

Signals must be available from outside the TAC Xenta controller.

What is the syntax requirement for expressions in TAC Menta?

Upper case for analog inputs and lower case for binary inputs.
