1.2 Overview of functions

What are ePS Network Services ?

The ePS Network Services support machine tool manufacturers and manufacturing companies with maintenance and services. This is carried out using software services that are available on a CNC control, S7 control, IPC or standard PC.

This requires both a control on the machine that complies with the specifications, and Internet access.

The ePS Network Services include:

Remote access

Remote access to the control via a secure Internet infrastructure. This service permits remote access to the control.

• Desktop control

• File transfer

• Chat

• Video ...

Control monitor services

Recording of events in a history and documentation of the current status of the control at this point. This allows the status of the device to be analyzed and compared with earlier states should a fault occur.

The current status of the machine is documented using the following events and data:

• Alarms, PLC events, time intervals, combinations of machine signals

• Limit value violation and time delay violation from condition monitoring

• Series of measurements/tests and operating performance monitors

• Manual help request by the machine operator in the event of faults

• HMI action log, machine data, NC status data

• PLC trace, PLC data blocks

• Certain files (e.g. log files) of the control

Condition monitoring services

Measurement and documentation of the current machine status on the basis of predefined, standardized tests and continuous recording of status characteristics (traverse path, traverse time and traverse operations for one axis). The test parameters can be defined centrally and configured with appropriate warning limits. Using series of measurements, it is also possible to identify trends and apply them as a basis for optimizing maintenance and service activities.

The machine operator can then carry out these predefined tests quickly and easily and without additional test equipment.

1-12 ePS Network Services, Function Manual (FH) - Release 12/2008

12/2008 1 Introduction

1.2 Overview of functions

The following tests and monitors are available:

• Circularity test

• Equability test

• Universal axis test

• Variable monitor (NC variable, PLC variable, freely addressable variable)

Data services

Save the current control archives (NCK and PLC archives) on the ePS Server. In the event of faults, they can be reimported into the controller in a controlled manner and used as reference for comparisons of control monitors.

Workflow services

Triggering of service and maintenance processes by notification via media that are internal and external to the system (SMS, e-mail, service cases). Planning, monitoring, and documentation of maintenance activities on the machine.

Maintenance schedules support you in the following tasks:

• "Look Ahead" maintenance relating to load and usage (see: Control monitors

with machine and service triggers)

• Automated triggering of operating sequences when faults are detected (see:

Maintenance schedules, maintenance jobs, fault help requests, and service cases).

• Planning condition monitors in terms of dates and content, and monitoring

their processing (see: Maintenance schedules, maintenance jobs and control monitors)

The Workflow Services can respond to all event sources of the Control Monitor Services and Condition Monitor Services.

Administration services

Functions for the administration of the system:

• Creation and administration of machines

• Creation and administration of users

• Assignment of access rights for external organizations

• Access to use data / invoices

Function Description

Unit Dimension of evaluated variable values

(e.g. °C).

Conversion of display scaling

Evaluation of variable values for the dimension adjustment, linearly through two defined value assignments.

The variables can be scaled linearly via two defined points for the display (e.g. byte value 16 corresponds to 20 °C, byte value 128 corresponds to 90 °C).

Bits Display of a variable in byte format; not as a

value, but individually as a binary signal for each selected bit. Variables configured as byte can also be displayed as individual bits (BOOL). If not all of the individual bits are required in the view, they can be specifically selected for the display.

Variable display: Changing the sequence

The sequence of the variables can be changed so that they can be compared directly next to each other.

PLC trace: Time/cycles display The horizontal axis is always displayed with a

millisecond specification for each cycle. This can be changed to the cycle number, each calculated with the starting point 0 from the trigger.

Display options PLC trace diagrams can be displayed in a

default setting that can be evaluated on every monitor.

A complete recording can be displayed in a compressed format, by means of a zoom setting in a single view. However, this may result in a loss of information. Every detail is displayed in an optimized compressed display, but in the smallest possible view. The minimum level of precision that can be set for the graph view is the pixel level, but marking should allow a cycle level of precision to be set dynamically.

Diagram/table A graphical or tabular display of the variable

values can be selected.

2.2.1 Visualization on the Internet PC

Description of functions

The performance and status of a machine and its modules can be analyzed with measurements and measurement series that have been performed on the machine. This includes measurement curves generated from the measurements and characteristics, as well as additional information about the measurement result. Trend curves can be generated from characteristics in measurement series. The machine operator can use the measurement results to make an analysis at a later point, while away from the machine. Status changes can be derived from the trend curves. Limit values will show whether any maintenance work is necessary at an early stage.

2.2 Variable monitors - Measurements and measurement series

Displaying the measurement results

You can view measurement results both on the machine operator panel and on the PC. Trend curves produced by measurement series can only be viewed on the PC.

The warning and critical limits of the characteristics can give the machine operator evaluation information about how far the qualitative state of the machine is from the limit criterion.

Fig. 2-16: Examples of time series

The trend curve can be generated from the measuring type-specific characteristics (characteristic over time) by cyclic repetition of individual measurements. This is used in particular as a basis for condition-oriented maintenance. For this, measurement series can be generated based on existing individual measurements. This ensures that the measurement series is based on the same measurement.

Measurement series are used as the basis for condition-oriented maintenance because the trend curve and the limit values provide a basis for planning maintenance activities.

How each test is conducted is described in Section 2.3 Test series on the machine.

The machine operator can view the measurement results on the operator panel of the machine and on the PC. Trend curves derived from measurement series can only be viewed by the operator on the PC.

2.2.4 Circularity test

Description of functions

The circularity test produces a polar plot of the circular path and circularity-specific characteristics:

Characteristic Meaning

Circular deviation The circular deviation is measured on the basis of

ISO 230-4 as difference between the maximum and

minimum radius at movement of a circle in one direction.

A value is calculated for each direction of movement.

Circular hysteresis As defined in ISO 230-4 the circular hysteresis is

determined by establishing the maximum difference of

measured radii on an angular position between the two

directions of movement.

The measurement type-relevant parameters are also specified. The goal is to test the drive dynamics and accuracy of the two axes involved.

2.2 Variable monitors - Measurements and measurement series

2.2.5 Equability test

Description of functions

The equability test result returns the torque/force measurement curve over the axis position and various torque characteristics. The characteristics are determined for each direction of movement separately. If nothing else is described for the characteristics, the characteristics refer to the position range without the acceleration and braking ramps.

Characteristic Meaning

Maximum torque The maximum returns the maximum torque in the

measured position range. With torque characteristics with linear trend, the proportion the trend is computed for determining the maximum torque.

Minimum torque The minimum returns the minimum torque in the

measured position range. With torque characteristics with linear trend, the proportion of the trend is computed for determining the minimum torque.

Average torque The characteristic returns the mean torque in the

measured position range with the configured speed. Independently of the direction, a larger value always corresponds to a larger torque in the direction of movement.

Standard deviation The characteristic represents the standard deviation of

the torque characteristic in the measured position range at the configured speed. With torque characteristics with a linear trend, the proportion of the trend is eliminated from the standard deviation.

Increase in the linear trend of torque characteristic

Maximum torque of the acceleration ramp

The characteristic indicates the increase in the change to the torque at position changes.

The characteristic indicates the maximum torque which is run in the acceleration ramp.

2.2 Variable monitors - Measurements and measurement series

For axes that also have a direct measuring system the overall rigidity curve over the axis position is also displayed. The rigidity is determined independently of the direction. The following rigidity characteristics are calculated:

Characteristic Meaning

Maximum rigidity The characteristic returns the maximum rigidity

value via the rigidity characteristic in the measured position range at the configured speed.

Minimum rigidity The characteristic returns the minimum rigidity value

via the rigidity characteristic in the measured position range at the configured speed.

Average rigidity For calculating the characteristic, the mean rigidity

value is determined in the measured position range at the configured speed.

Standard deviation of the rigidity

For calculating the characteristic, the standard deviation of the rigidity is determined in the measured position range at the configured speed.

The equability test notifies the machine operator of faults and interference resistances from feed axis elements. The curve of the recorded values indicates at which axis position the disturbance is located. A trend analysis of the characteristics will indicate any change in the status of the drive train.

2.2.6 Universal axis test

Description of functions

With the universal axis test different characteristics are calculated which describe the mechanical properties of an axis.

Characteristic Meaning

Residual torque (Res) This characteristic is not supported. Coulomb friction (Coul) The Coulomb friction describes the proportion of the

friction which is independent of the speed. Mixed friction (Mix) This characteristic is not supported. Viscous friction (Visc) This characteristic describes the proportion of the

friction which increases linear to the speed Moment of inertia (Inr) The characteristic describes the entire moment of

inertia that needs to be moved by the electrical

drive. This includes the moment of inertia of the

motor. Torque offset (Const) With axes which are pretensioned in one direction

(e.g. vertical axes) the characteristic indicates the

torque required for compensating for this pretension. Coherence (K) The coherence indicates how much a model

parameterized with the calculated characteristics

can simulate the measured torque characteristics. Circular deviation (G) The characteristic describes the maximum position

deviation with axis movement on the basis of a

velocity profile. The calculation of the characteristic

is based on ISO 230-4 as is the case with the

circularity test.

The measurement type-relevant parameters are also specified.

2.2.7 Variable monitors

Description of functions

Variable monitors enable the recording in the control of changes over time of any status data. The variable monitors are essentially for long-term recording in slow data recording cycles (as opposed to the PLC trace).

Up to 32 variables can be recorded in a common cycle in a variable monitor. The PLC variables recorded can be from the PLC environment: inputs, outputs, counters, flags, and any data addresses in PLC blocks. From the NC environment, they can be machine data, setting data, system variables and others.

The variables recorded can be scaled and assigned freely definable units. Individual variables of a variable monitor can be identified as counting variables (e.g. workpiece counters). These variables can be used in the configuration of interval triggers to trigger recurring actions after a certain number of counting units have elapsed. Counting variables are counted up monotonically. Resetting of the variables in the control is compensated for by the system because the count is resumed on the basis of the last value before reset.

Limit values can be configured for each variable for automatic monitoring of the state. Actions can be triggered when limit values are violated. This is the same as described for the control monitors.

• Confirmation of the parameters of the measurement and display of the

measurement series contained in the test series

• A contour test to check collision can be performed before the actual

measurement

• Check release by the PLC

• Machine operator sets AUTO mode and feedrate override to 100% on the

control

• Machine operator presses NC START on the control

• Perform machine-specific prolog of the measurement movement

• Perform the measurement movement with data recording

Notice

Please observe the information on the operator panel!

2.3.2 Requirements for performing the test

Requirements on the control

When making measurements, the machine axes must be moved with precisely the motion profile that is defined in the NC program. In addition, it must also be guaranteed that the motion is also executed in the machine coordinates. The following functions in the NCK could be problematical when carrying out measurements (sample selection):

• Asynchronous subprograms

• Static synchronized actions

• Coupled axes

• Kinematic transformations

• Superimposed (overlaid) motion, such as DRF, external work offset

• Tool length compensation

• Functions, that influence the velocity, such as G95

• Functions that change the position, such as DIAMON

• Axis replacement/geometry axis replacement

• Axis is passed over to the PLC (PLC axis)

The NC program for performing the measurement does not affect the functions listed above. Only the zero offsets are disabled and the offset produced by DRF and external zero point offset is compensated statically, i.e. the value is corrected by the value that applies at the beginning of the measurement.

Orientation transformations are a special case. It is possible to execute measurements with the geometry axes when transformation is active. However, the offset of the geometry axis coordinates produced by the orientation axes is not compensated for. It is therefore advisable to deactivate transformation.

Couplings between axes should be separated before the measurement movement (e.g. in the prolog program). The NC program of the ePS system does not separate couplings. The ePS system assumes that it is possible to load, select, and start an NC program (with subroutines) downloaded from the ePS system on the machine in a particular channel. For machines where the PLC prevents the machine operator from selecting or starting any NC program, the PLC can communicate with the ePS system via DB10.DBB90 or DBB91.

Machine data must be set in the control to acquire data for the condition monitoring measurements. Not only Trace Server machine data but also MD 36730: DRIVE_SIGNAL_TRACKING must be set.

Drives that are linked via Profibus must be handled differently. Here the Profibus configuration must be changed so that the torque values can be transmitted to the control cyclically.

2-51

2 Maschine information 12/2008

2.3 Test series on the machine

Prerequisites of the machine

The measurements for condition monitoring assume that the machine axes can be traversed separately with precisely the motion profile that is defined by the NC program for performing the measurements.

Machine designs with parallel kinematics, for example, that do not allow this are not suitable for condition monitoring by ePS Network Services.

Note

Axes that can only be programmed as positioning axes can only undergo the synchronized axis test. The circularity test or universal axis test cannot be performed on these axes.

NC programs are downloaded to the control to carry out the axis tests. There must be approximately 100 KB free NC program memory available.

A variable $AC_MARKER is used for executing the NC programs. You can configure the variable index. The default setting for the index is value 5. You must ensure that the $AC_MARKER variable of the configured index is not used by other control functions.

Note

The ePS system does not check whether the configured $AC_MARKER variable is also used by other control functions.

2.3 Test series on the machine

2.3.3 Prolog and epilog program for a measurement

Description of functions

To prepare the control making it suitable for the test, an NC program that has been specially adapted to the machine by the machine manufacturer or end user is executed at the beginning of the test. This means that machine settings can be specifically changed so that the test can be performed (example: Disabling transformations and couplings, resetting pre-set G codes).

Suitable programming of the prolog and epilog program can influence how the test is performed. When a test series is carried out, individual measurement series can only be hidden under the tested conditions (e.g. due to a risk of collision).

The prolog and epilog program is reloaded into the control with name "N_EPS_PROLOGEPILOG_SPF" every time a test is run. The NC program editor of the operator panel (=HMI-Advanced) can be used to modify this program.

After the test has been performed, the ePS system automatically checks whether the prolog/epilog program has been changed and, if required by the machine operator, stores it permanently.

2.3.4 Program example

Description

Here is a commented example program to illustrate how the prolog and epilog program can be used to prepare the machine specifically for a certain test. The structure of the program is as follows:

Prolog for the test series:

This section of the program is only executed once at the beginning of a test series and also on each single measurement outside a test series. This block contains everything that has to be executed irrespective of the type of test or the axis that is to be measured. For example, in this case G codes that are preset on the machine via machine data (G95, DIAMON, etc.) could be deactivated, the tool could be unloaded, the workpiece removed, and all axes moved to a safe initial position.

Prolog for each measurement:

This section of the program is executed before each measurement, irrespective of whether the measurement is part of a test series or is performed individually. This block can be used with call parameters to check which axis is to be tested, which test type is to be conducted, and with which parameters the measurement will be performed. For example, when testing certain axes, it may be necessary to move other axes to another position than the basic position, or the starting point for the measurement cannot be approached directly (circularity test). Certain actions could

2-56 ePS Network Services, Function Manual (FH) - Release 12/2008

12/2008 2 Maschine information

2.3 Test series on the machine

also be performed depending on the position range in which the measurement is performed.

When programming axis movements, it is important to ensure that the parameters of a measurement always refer to the machine coordinate system if they represent positions. The example program shows how the axis movement can be offset into the machine coordinate system using the command SUPA.

It is possible to test the name of the measurement series in the program and to execute special functions for a certain measurement series. However, that should be limited to special cases because the parameters of a measurement series can be changed at any time without its name having to be changed.

Epilog for the test series:

This section of the program is only executed once at the end of a test series and also after each single measurement made outside a test series. The actions that are necessary for minimizing the work the machine operator must do in order to resume the machining process after performing measurements should be executed in this block.

Epilog for each measurement:

This section of the program is executed after each measurement, irrespective of whether the measurement is part of a test series or has been performed individually. It is useful for undoing actions performed before the measurement. It may be necessary to move all axes back to their safe initial position.

2.3.5 Commissioning measurements

Description of functions

The prolog and epilog program must be edited in order to perform measurements. If measurements are performed on a machine for the first time, or if the prolog and epilog program has been deleted, then a preconfigured prolog and epilog program takes effect, which prevents the further execution of the NC programs as the NC program code runs in an endless loop. This part of the preconfigured prolog and epilog program must be deleted. A program code adapted to the requirements of the machine must be used for the prolog or epilog.

2.3.6 Release protocol between PLC and ePS system

Description of functions

Communication is performed between the ePS system and the PLC for the execution of a test. The ePS system signals that a test will be executed with axis movements. The PLC can then put the machine in a suitable state and signals to the ePS system that the test can begin.

The protocol allows test series that are to be carried out with a maintenance schedule to be executed in a fully automatic manner while being monitored by the PLC.

More details are given in /R1/.

2.5 Remote access

2.5.1 Remote access functions

Overview

Remote access is an efficient and low-cost way of providing support for machine tools and production equipment via the Internet.

In the event of a fault, the service organization of the machine manufacturer has fast access to important control data and diagnostic functions. In that way, the machine manufacturer or maintenance department of the end user can immediately analyze the current condition of the machine in which a fault occurred.

Remote access avoids time-consuming in-situ service assignments or at least helps prepare for them better. Machine manufacturers can therefore reduce their warranty costs while providing more efficient servicing support for their end users.

Summary of the most important functions

The following functions are available during a link with the machine control. These functions enable diagnostics and fault rectification via the machine control. It is usually up to the service technician to execute the function. The technician can work on all problems via remote access on a PC with a mouse and keyboard.

Function Property Chat

Desktop sharing

Transfer file

Video

Recording and playback

Remote printing

Permits the exchange of text messages with a participant in the service session. Permits the display and remote control of machine control. For security reasons, however, it is not possible to initiate machine movements or to start NC programs. Within the function, areas of the screen can be marked with the Annotate function, which is similar to text marker. Permits the transfer of single or multiple files or directories. Transfer can be from the service PC to the machine control or vice versa. This enables the import of patches to correct errors, for example. The machine control can also be updated quickly. Even complex NC programs can be transferred to the service employee for offline testing or to the service technician for modification via file transfer. Permits the transmission of video images of a webcam to the machine control Enable storage of the entire service session or parts of the service session for training or archiving purposes. Permits the printing on a local printer of the service PC of documents or graphics that are displayed on the control. This also installs the printer driver "Active Touch Document Loader" on the machine control.

2.5.2 Functions of a service session

Description of functions

The following functions are available during a link with the machine control. These functions enable diagnostics and fault rectification via the machine control. It is usually up to the service technician to execute the function. The technician can work on all problems via remote access on a PC with a mouse and keyboard. Several service employees and specialists can work together in a service session to solve a problem. The service technician who establishes the service session first keeps control of all functions throughout the service session. All other service technicians can only observe what is going on. If necessary, the first service technician can pass on and take back control to or from another service technician within a desktop control session. The entire session can also be passed on to a second service employee.

Function Property

Dialog via text window (Chat)

Remote display of the operator interface HMI (Desktop view)

Remote control of all operating functions (Desktop control)

Data transfer (Transfer file)

Conference link (Transfer session)

You can exchange text messages with the machine operator online via a chat window. The "Chat" function can be started without the need to obtain the machine operator's agreement. The "Desktop view" function is used to observe all operating steps at the operator interface of the machine HMI. That enables you to detect remotely on the service PC which functions are triggered on the control. You can provide the machine operator with instructions using the annotation function. You can use the "Desktop control" function to execute all operating functions of the machine control via remote access. For safety reasons, however, it is not possible to initiate machine movements or to start NC programs. You can use the "Transfer file" function to transfer data between the machine control and your service PC. Data transfer is possible in both directions. Which functions and views of drives are used within data transfer depends on the type of session set. You can use the "Assist online support" function to invite other specialists to join the teleservice session. The person you invite to join a teleservice session that is currently underway has the option of either providing active support or simply participating in the teleservice as an observer.

3.1.1 Creating maintenance schedules

Description of functions

The maintenance schedules contain the maintenance-related tasks to be performed on the machine (maintenance, inspection, and servicing).

Maintenance procedures may be logged in the schedule in a purely text-based format; alternatively, "intelligent" maintenance procedures, which automatically determine data via axis tests in order to performing purposeful status-oriented maintenance, may also be logged.

• The schedules are activated in a control monitor either on a timer- or event- triggered basis or as a combination of both. The maintenance schedule then becomes a maintenance order and is due for the responsible organization. A schedule always applies to just one machine.

• The maintenance jobs are produced on a time-controlled basis, in time intervals, on an event-triggered basis, or in event-triggered intervals. This is executed via the universal trigger of a control monitor.

• A maintenance job via a control monitor only becomes pending when the control monitor is initiated, and is then due immediately.

• Maintenance schedules can be updated at any time: This only affects maintenance schedules that will be output after the changes have been made, and not those that have already been output. This also applies if a schedule is deleted.

Note

If users are logged on to the control as machine operator, they can process the pending jobs. For machines with version V3, they do not have to be a member of the target organization; for machines of version V4, they require authorization to act as machine operator (MO) for this machine.

3.1.2 Configuring variable monitors

Overview

You configure a variable monitor in the following steps:

1. Select the variable monitor or create a new variable monitor.

2. Name the variable monitor; comments and icons can be added as an option.

3. Define the PLC variables.

4. Use a control monitor to execute the variable monitor.

Selecting or creating variable monitors

Since it is possible for each machine to have several variable monitors, there is the option of sorting them in the overview display either by their names or by the two classification fields. In addition, it is possible to filter them by searching for specific parts of text that appear in the Name and Variables columns using the "Search text" box.

3.1 Maintenance

Notice

PLC data source: By default, PLC addresses are restricted to the address range of the smallest

PLC. To remove this restriction if you are using a more powerful PLC and want to use

the addresses in ePS, you must increase the corresponding values in the trigger DB (DB239 in ePS Standard) in DW8 for inputs, DW10 for outputs, DW12 for bit memory, DW14 for timers, and DW16 for counters to the available address ranges. You must then restart the PC on which the ePS client is installed.

Warning

PLC data source: Using the trigger DB with an increased address range can cause the PLC to shut

down when the higher addresses are used in ePS configurations if this address range is not actually available to the connected PLC.

Using (a) control monitor(s) to execute the variable monitor

The "Trigger variable monitor(s)" diagnostic action is used to detect the PLC variable values promptly and store them on the ePS server. It is only possible to access the data manually via the machine events or variable monitor data series. Limit value triggers can be used to react automatically to the variable values via control monitors.

3.2 Configuring measurements and measurement series

Description of functions

Configuration of measurements and measurement series it when you define the parameters required for measurement. The configurations created are always stored with the measurements and can be used again to repeat the measurements. That especially applies to measurement series. The configuration of a measurement series ensures that measurements are made with the same settings every time. This permits evaluation of the progression of characteristics over time.

In addition to parameters for performing a measurement, the limit values of the characteristics are also configured. Limit values can be configured for measurement series. The configuration is only possible on the PC. Individual measurements that do not belong to a measurement series cannot have limit values.

Availability and privileges

On the operator panel, a measurement is configured or a measurement series configuration changed only during the measurement procedure. On the operator panel, it is only possible to create a measurement series based on a measurement being performed.

On the PC, it is possible to configure measurement series. The authorization required to configure measurements and measurement series is described in detail in the Appendix.

Configuring the limit values

With the equability test, one movement is carried out each forwards and backwards. The characteristics are calculated separately for each direction. As standard limit values are defined for the characteristics and are the same for both directions of movement.

Optionally limit values can be entered which can have different values for both directions for each characteristic.

3.2.4 Performing test series

Overview

Test series are used to automate measurements for condition monitoring to a great extent. A test series can contain any number of measurement series. These measurement series are performed one after the other in the defined order when a test series is run. An machine operator is only required at the machine for the purpose of starting the test series.

The measurements are made and measurement results stored without any further operator actions.

Description of functions
