Necessary safety measures
The device measures direct laser radiation, but does not emit any radiation itself. However, during the measurement the laser beam is directed at the device. This produces scattered or directed reflection of the laser
beam (laser class 4). The reflected beam is usually not visible.
Protect yourself from direct and reflected laser radiation while working with the device by taking the following
measures:•

Wear safety goggles adapted to the power, power density, laser wavelength and operating mode of thelaser beam source in use.

•

Wear suitable protective clothing or protective gloves if necessary.

•

If possible, also protect yourself from direct laser radiation and scattered radiation by using separating
protective devices that block or attenuate the radiation.

•

If the device is moved from its aligned position, increased scattered or directed reflection of the laser
beam occurs during measuring operation. Mount the device in such a way that it cannot be moved unintentionally, i.e. by bumping or pulling the cables•

Install safety switches or emergency safety mechanisms that allow the laser to be switched off immediately.

•

Use suitable beam guidance and beam absorber elements which do not emit any hazardous substances
when irradiated.

Device description

4.1

Functional description

PowerMeasuringModule PMM AP3sM

The PMM is used to measure laser power. After opening the shutter, the laser beam hits the absorber andscattering light is registered by a photodiode. The absorber and the photodiode are protected from contamination by the protective window. The shutter and the caps on the ports protect the PMM from contamination. Thus, the PMM can be used directly in the production environment in the process zone.
The PMM operates without cooling water and compressed air. The absorber cools itself down by releasingheat into the environment.
Thanks to the availability of various fieldbus interfaces, the PMM can be integrated in nearly every existingmachine. The measurement results are transferred directly to the PLC.
The PMM is equipped with an optics extension in which the protective window is enclosed. For replacing the protective window outside the PMM the optics extension can be removed (see chapter 15.3.2 on
page 82).

Measuring principle

The PMM offers a fast, passively cooled power measurement according to the calorimetric measuring principle.
The absorber of the measuring device is briefly irradiated with the laser beam. The irradiated energy is determined by the temperature rise of the absorber.
The photodiode simultaneously determines the laser ontime. The high-frequency sampling rate of thephotodiode enables single pulse detection for pulses not shorter than 50 μs.
Thus, in addition to the average power, the peak power can also be calculated. In the second step, the actual laser power is calculated from the absorbed energy divided by the laser ontime.

Explanation of the product safety labels

Potential hazard areas are marked on the device with the symbols „Do not grab inside“ and „General warningsign“.
4.3.1

Warning of hand injuries/damage to the device

Do not grab inside
Under the optics extension is an opening with the absorber. Touching the hot absorber can cause serious
burns. Touching the absorber can lead to burn-in by the laser radiation at the points of contact. Burn-incauses damage to the absorber and increases the scattered radiation. Do not grab inside the opening.
General warning sign
The protective window is hot after a measurement! Do not replace the protective window directly after ameasurement. Let the device cool down for an adequate period of time.
Contamination and fingerprints on the protective window can lead to damage or destruction of the protective
window during measuring operation. When exchanging the protective window wear suitable gloves.

Laser parameter setting

For correct measurements and to protect the device from damage, the following parameters must be observed and adhered to.
8.1

Setting the laser rise time

The applicable irradiation time is between 0.1 s and 1.0 s, which has to be transferred to the laser controller
as pulse duration/burst duration.
For high measurement accuracy, make sure that the rise time of the laser does not exceed 1 % of the irradiation time (in some cases, even 2 % may be acceptable).
Example: If an irradiation time of 500 ms is selected, the rise time of the laser must be < 5 ms. Many industrial lasers have a rise time < 0.1 ms, so this point can be ignored in most cases.

Maximum power density

To avoid damage to the optics under the protective window, the maximum power density of 150 kW/cm²
must not be exceeded at the optics.
Depending on the laser power, the following minimum beam diameters must be observed:

Tab. 8.1:

Minimum beam diameter depending of the laser power

The power density in kW/cm² is calculated according to the formula:

Formel 8.1: Calculation of the power density

To determine the maximum laser power, the result is weighted with a safety factor of 2. The safety factor
compensates the ratio of maximum to average power density of a Gaussian beam (far field). The maximum
laser power in kW depending on the beam radius is calculated according to the formula:

8.3

Minimum and maximum energy input per measurement

The measured temperature rise in the absorber is decisive for an accurate and reproducible measurement.
Regardless of the starting temperature, an energy input of approximately 400 J to 1 000 J per measurement
is recommended.
Example: At 1 kW laser power the recommended pulse length is 400 ms.
E = P · t = 1 000 W · 0.4 s = 400 J

Measuring range as a function of the absorber temperature

The minimum energy input indicates the lower limit values with which measurements can still be performed
within the specified accuracy. The maximum energy application value specifies the limit at which the absorber reaches its permissible limit temperature. The energy, e.g. for multiple measurements (repetitive measurements) can be distributed across the range shown in green.
If the absorber temperature is higher than 80 °C, no further measurement should be performed. In this case,please wait until the absorber temperature has fallen below 50 °C (depending on the selected energy input).
If a high repetition rate is prioritized over the uncertainty of measurement, a lower energy per measurement
may be used, e.g. down to 200 J.
Please take the limit values from Fig. 8.3 on page 37, Tab. 8.2 on page 38 and Tab. 8.4 on page 39.

Number of measuring cycles (repetitive measurements)

With a start temperature of 20 °C, the absorber can accomodate a heat quantity (= energy) of approx.
3 500 J. PRIMES recommends an energy input of approx. 400 J to 1 000 J per measurement in order toachieve the highest possible measurement accuracy.
Measurements can be repeated in rapid succession until the absorber reaches 80 °C. Then, a cooling cyclein the range of 1-2 minutes is required until further measurements are possible. For repetitive measurements,
see chapter 8.5 on page 39.

NOTICE

Calculation of the irradiation time

The selection of a certain irradiation time is based on three different criteria:
1. The minimum irradiated energy should amount to at least 10 % of the total capacity of the absorber (Variable: “Max. Capacity”). This requirement ensures best measurement accuracy (5 % may be acceptable if
the repetition rate is a priority). See also point 2.
2. In case of a repeated power measurement within a short period of time, a maximum of 50 % of the residual absorber capacity of the test piece must be used. (Variable: “Remaining Capacity”)
3. The irradiated energy may not exceed the “Remaining capacity”, otherwise the absorber may be overheated during the measurement.
With the following formula the irradiation time can be determinated:
Δ t = Remaining capacity / Laser powerΔt=

Irradiation time

Remaining capacity=

Remaining capacity after a measurement

Laser power=

Laser power of the laser beam

A constant irradiation time ensures a best possible performance and repeatability.

Even with absorbers at room temperature the remaining capacity does not reach the "Maximum
capacity". This is due the fact that the “Maximum capacity“ refers to an absorber temperature of
0 °C.

Revision 00 EN - 05/2023

35,0(6PowerMeasuringModule PMM AP3sM

The irradiation time of 100 ms leads to an irradiation of 800 J. This means, the minimum amount of energyof 400 J is clearly exceeded. Furthermore, this irradiation time enables two more power measurements, thatcan be carried out immediately.
8.7

Measurement with pulsed lasers

When measuring pulsed lasers, the technical specification according to chapter 17 „Technical data“ onpage 88 must be observed.
When using pulsed laser radiation a correct irradiation time measurement up to a pulse frequency of 10 kHz
and a duty cycle of 50 % is possible. In case of ontimes/offtimes shorter than 50 μs a correct irradiation timemeasurement is not possible.
Measurements outside the specification may result in an incorrect calculation of the number of pulses. Thisaffects the calculated average power. But not on the measured energy.
When measuring pulsed lasers, as of firmware version 3.2, the power (measured power) is calculated with a corrected burst duration (see Fig. 8.4 on page 40).
For devices with former firmware versions, the power (measured power) is calculated with theuncorrected burst duration. This leads to an increased value of the average power.
With pulsed lasers, the device detects the number of pulses n and the number of pulse pauses n-1 (the last
pulse pause toff is not measured, for physical reasons).
The burst duration here is (ton + toff) ∙ n - toff. This leads to a significantly increased value of the power (measured power) for a low number of pulses.
The power is therefore calculated for devices with firmware version 3.2 and higher on the basis of a corrected burst duration: (ton + toff) ∙ n (see Fig. 8.4 on page 40).

The deviation of the laser power is the ratio of corrected to uncorrected burst duration:

Deviation =(ton + toff) ∙ n(ton + toff) ∙ n - toff

The values for ton and toff illustrated in Fig. 8.4 do not correspond to the values for „Ontime“ and „Offtime“ inthe registry settings: Ontime = ton ∙ n and Offtime = toff ∙ (n-1).
For cw lasers respectively one pulse, the average power corresponds to the maximum power of one pulse.

Measurement cycle details

The power measurement cycle includes 3 steps:
1. Preparing the measurement
2. Executing the power measurement
3. Evaluating the power measurement
The details of these steps are discussed below:
10.1

Preparing the measurement

The readiness of the device is subject to 3 conditions:
1. The shutter is open.
2. The absorber still has the capacity to absorb the energy of a measurement
3. No other measurement cycle is activated10.1.1

Opening the shutter

The shutter is opened by a gear motor with a friction clutch. The bit “open shutter” in the command byte
issues the command to open the shutter. The gear motor requires less than 5 seconds to open the shutter
completely.
As soon as the shutter has reached the open position the “shutter open”- bit changes to the value 1 in the“Status 1” byte. The command bit “open shutter” can then be deactivated. Closing the shutter is done in thesame way.
Command.open shutter
command.close shutter
status1.shutter open
status1.shutter is closed
Fig. 10.1:

Shutter control timing diagram

Step 2 according to chapter 10.1 requires a delay time. The waiting time allows the absorber to cool down
so that a new measurement is possible. The waiting times can be found in chapter 8.5 on page 39.
At step 3 according to chapter 10.1 the measuring readiness is automatically established again after the endof the current measuring cycle.
10.1.2

Determination of the irradiation time

The irradiation time is to be determined according to the regulations stated in chapter 8.6 „Calculation of theirradiation time“ on page 39.

Execution of the power measurement

The PMM is ready for measurement when the “Ready for Measurement” status bit is set (shutter is open,
temperature is OK).
To initialize the PMM for the measurement the external control system must set the “start” bit in the “Command” byte (please see Fig. 10.2 on page 48).

Fig. 10.2:

Timing diagram of the measurement cycle

The PMM answers the starting command with an “acknowledge” in status byte1.
As soon as the PMM is ready for measurement the “ready” bit is set in the status byte1.
Before starting the laser pulse, check that statusbyte1.Bit 0 is set to 1.
From this point on, the laser can irradiate the absorber using the calculated irradiation time (see chapter 8.6„Calculation of the irradiation time“ on page 39.
If the shutter is not in the open position or a laser pulse is detected, the “ready” status is deleted.
After the laser pulse, the PMM can identify the laser pulse due to the temperature rise of the absorber andthe signal from the internal photodiode.
The following thermalization period of the absorber is indicated by the bit “running” in the status byte.
At the end of the thermalization phase (approx. 3 seconds), the measurement result is calculated and the“measurement finished” bit is set. The results of the measurement can be displayed now.
If the measuring procedure is supposed to be aborted without a measurement and the shutter is
supposed to be closed again, a reset has to be carried out (Do_reset; set bit 7 in the command
byte, see Tab. 11.2 on page 51 ).

10.3

Evaluate measurement

The data generated during the measurement is stored within the variables. The measured values within thevariables can be found in chapter 11.3 „Variables“ on page 53.

Resetting the device
1. Check at output XG2 that „Measurement finished“ bit 15 is set to 1.
2. Apply a signal with a duration of min. 200 ms to input XG1, bit 3 „Reset“.
x After the reset „Measurement finished“ bit 15 is set to 0.
x The status of the PMM can then be read at the output lines.
Opening the shutter
3. Apply a signal to input XG1, bit 0 „Shutter opening“.
This signal has to be reset to 0 again after the signal at output XG2, bit 9 “Confirmation command closing” is set.
x The open shutter is indicated at output XG2, bit 0 „Shutter is open“.
Checking the temperature of the absorber
If the temperature of the absorber is too high, output XG2 bit 11 “Absorber to warm” is set to 1.
This bit is only set if the max. absorber capacity has been reached. This bit is reset due to thermal conduction.
Starting the measurement
A measurement may only be performed with the shutter open and sufficient absorber capacity.

NOTICE
Damage/Destruction of the device
The permissible temperature of the absorber must not be exceeded.
X When programming the laser system, please ensure that no measurement can be started, as longas the absorber is too warm (bit 11 = 1, see section “Checking the temperature of the absorber”).
4. Apply a signal to input XG1, bit 2 “Start measurement”.
This signal has to be reset to 0 again after the signal at output XG2, bit 10 “Confirmation start measurement” is set.
x With the signal at output XG2, bit 14 „System waiting for pulse“, the PMM indicates readiness for measurement.
Activating the laser pulse
The absorber capacity of the PMM is max. 3 500 J. The pulse should contain at least 400 J.
Example: For a laser power of 4 000 W, the pulse length should be at least 400 : 4 000 = 0.1 s.
The irradiation time does not have to be communicated to the system because the PMM measures it itself.
x After the laser pulse has been triggered, after a few 100 ms, output XG2, bit 13 „Measurement in process, Pulse received“ is set to 1.
Waiting for the measurement result
Ten seconds after activating the signal at output XG2, bit 13 “Measurement in process, Pulse received“”, thebit is reset and bit 15 “Measurement finished” is set to 1.
Simultaneously, the bits 0 to 14 show the measurement result in binary form.

DeviceNet® or EtherNet/IP™ connection

DeviceNet® was developed by Rockwell Automation and the user organization ODVATM (OpenDeviceNet®
Vendor Association) as an open field bus standard, based on the CAN protocol. DeviceNet® is in accordancewith the European standard EN 50325.
Just like ControlNet™ and EtherNet/IP™, DeviceNet® is part of the family of CIP™-based networks. CIP™
(Common Industrial Protocol) forms the common application layer of these three industrial networks.
DeviceNet® is an object-oriented bus system which works according to the producer/consumer procedure.
DeviceNet®-devices can be client (master) or server (slave) or both. Clients and server can be producer, consumer or both.
Based on DeviceNet® the field bus EtherNet/IP™ was developed, which integrates the devices networked
via EtherNet/IP™ seamlessly – automatically via mapping in the I/O tree of the RSLogix programming tools.
As an option, the configuration software tool (RSNetWorx), known from DeviceNet®, can be used for the
integration of further field devices into the network.

Data model

For the communication of the PMM with the field bus, a specific internal field bus module is used. The PMM
is controlled by a command-byte, which encodes four commands. The PMM data are stored in an “Array ofByte”, which contains 66 elements. In the table of variables only entries up to byte 56 can be found. The remaining bytes contain information which is used for the calibration of the device and is not handled by a user.

Data structure between PMM and control

The PMM stores the data in the format 2 byte Integer and 4 byte Integer. With EtherNet/IP™ and
DeviceNet®, the data is arranged in the “Little-Endian” format.
The field bus module used in the PMM generally only supports the “Array of bytes” and no tags, as definedby the CIP™ (Common Industrial Protocol). The variables of the PMM can therefore not be read directly fromthe bus.
13.3

PMM with DeviceNet®

With DeviceNet®, the data is transferred to the control via a scanner module. As an example, the data transfer of a CompactLogix 1769 by Allen Bradley is displayed here.
The measuring data of the PMM is written into the integrated communication module in the form of 2 byte Integer and 4 byte Integer. The communication module transfers this data as “Array of Byte” to the bus. Other
data types are not supported.
The scanning module 1769-SDN stores the data as “Array of DINT” (4 byte Integer) in the area “local” of thecontrol. The control does not contain direct commands which can carry out a type conversion. Therefore, thedata is copied to the target variable in a two-step procedure.
1. Step:
The data range of the type “Array of DINT” is copied to a variable range “Array of Byte” (see Fig. 13.3 on
page 60, copy command A). By means of this copying process, data cannot only be copied with thestart addresses modulo 4 (i.e. 0, 4, 8, 12, 16, 20 …), but every start address is possible.
2. Step:
The data is copied to the user-defined data types (see Fig. 13.3 on page 60, copy command B). The
data is then available within the control.

Revision 00 EN - 05/2023

35,0(6PowerMeasuringModule PMM AP3sM

The copying process is done with an add-on instruction (AOI) of the control software:
