True

(T/F) Alarms are only used for serious notifications?

False

(T/F) Alarms can monitor increasing/decreasing values to trigger alarm conditions. These are known as

analog alarms?

True

(T/F) An Analog alarm is triggered: When the value of the trigger tag is between the upper and lower-limit values.

False

(T/F) Any alarm that requires an acknowledgment can be assigned to an alarm group?

True

(T/F) Downloading to the HMI can be done in online or offline mode.

True

(T/F) The HMI device must always be in "Transfer" mode to download?

False

(T/F) The analog input on our S-7 1200 PLC was 4-20mA.

False

(T/F) An Axis Technology Object is used for controlling PID.

True

(T/F) When working with an Axis Technology object the commissioning tool is used to check the current status and error information of an axis and drive.

False

An axis technology object is best for controlling:

Both are correct; servo motors and stepper motors.

When configuring an axis technology object you must specify:

All of these; a direction output, an associated high speed counter, a pulse output.

When working with an axis Technology object the _____ tool is used to detect the status and error information of an axis and drive.

Diagnostics

Data is exchanged between the PLC and the HMI via _______.

Tags.

HMI's can communicate with the PLC by using...

All of these; MPI, PROFIBUS, Industrial Ethernet

To associate HMI screen elements with data in the PLC:

HMI Tags are associated with PLC Tags.

______ can be used to create a zip archive that contains the HMI project and a program for a project transfer.

Pack and Go.

An analog alarm is triggered:

Either a or b; (a) When the value of the triggered tag is above the upper-limit value. (b) When the value of the triggered tag is below the lower-limit value.

What Digital Input addresses are available on the S7-1500 PLC

%I10.0 thru %I13.7

What Digital Output addresses are available on the S7-1500 PLC

%Q4.0 thru %Q7.7

The FMS-200 uses _______ to step through its program.

Shift left instruction and SR flip flops

When power is switched from Stop to Run the CPU executes a complete restart by executing ______.

OB100

Before an analog value can be processed by the CPU it must be:

Converted from analog to digital.

To override the value of a physical input or physical output, you would use a:

Force table

According to the Stepper motor video a simple stepper motor system is comprised of four elements, User interface, Indexer, ______, Motor.

Driver

The three step modes of operation for a stepper motor are full step, half step, ______ step.

Micro

What is a technological object?

A technological object is any physical or digital entity that plays a role in the automation, control, or execution of industrial and technological processes.

What is the difference between an axis and a drive?

An axis is the technology object while the drive is the controller for either a stepper or servo motor.

What is the function of the enable output?

To make a PLC input enable a designated output to operate a drive.

Describe what hardware limits are and how they function.

Hardware limits are physically connected to inputs on a PLC. If the drive goes too far in either CW or CCW direction, the hardware limit will change states.

Describe what software limits are and how they function.

Software limits are high and low numbers set by the user in relation to position. These are used so the software limits are reached before the hardware limits. If we tell a drive to go beyond the software limits that're set, it will not do so.

What is the purpose of homing an axis?

To establish a home position. This is used for absolute positioning.

What are the basic steps that must be completed before an axis can be controlled with motion instructions?

MC_Power and MC_Home.

What is a MC_Power instruction used for?

The MC_Power instruction enables or disables an axis.

Describe the 4 modes of homing available in a MC_Home instruction.

Active homing - Done automatically

Passive homing - Done by the user

Direct homing absolute - Steps in relation to the home position.

Direct homing relative - Steps done in relation to the drives current position.

What is the difference between incremental and absolute moves?

Incremental - Movement is relative to the drives current position. Absolute - Movement relative to the drives home position.

What instruction can be used to acknowledge axis errors?

MC_Reset

Draw and calculate voltage, current, resistance and power for a voltage divider circuit. 10K Ohm Pot, 11 V for the Pot.

What are three programming techniques we can use for programming a stop light.

Comparator, Set and Reset bits, Flip Flops, etc.

How are HMI's useful to both operators and maintenance personel.

HMI's display a large amount of useful information, as well as serve as an interface to command the machine. The HMI can displace IO's, statuses, alarm conditions, and more. This allows the operators and maintenance to diagnose and troubleshoot both simple and complex problems that arise.

An HMI application should provide enough information to those involved...

who operators or maintenance personnel that work on the machine.
