Residual dangers

The ClipX system is a state-of-the art unit and as such is reliable. The scope of supply and performance of the ClipX system covers only a small area of measurement technology however. In addition, equipment planners, installers and operators should plan, implement and respond to the safety engineering considerations of measurement technology in such a way as to minimize residual dangers. For example, automation equipment and devices must be designed in such a way that adequate protection or locking against unintentional actuation is provided (e.g. access controls, password protection, etc.). When devices are working in a network, these networks must be designed in such a way that malfunctions in individual nodes can be detected and shut down. Safety precautions must be taken both in terms of hardware and software, so that a line break or other interruptions to signal transmission do not cause undefined states or loss of data in the automation device.

Mounting

Procedure

1. Use a size T10 Torx screwdriver to remove the screws indicated in the picture.

2. Keep the screws, because you should reuse them.

3. Make your mounting bracket. The material should be about 1 to 2 mm thick, to enable you to reuse the

original (M3) screws. The space between the two screws is 43.7 mm.

4. Fix your mount either using the original screws or using M3 screws penetrating a maximum of 5 mm into the housing. Fasten the screws only hand-tight.

Important: You must ground the ClipX housing, such as by way of the mount.

The ClipX features IP20 protection in accordance with EN 60529 (protection against touch by fingers; protection against foreign bodies of Ø > 12 mm).

The ClipX is supplied as standard with easy-fit push-in terminals. But you can also obtain screw-type terminals from Phoenix Contact (https://www.phoenix-

contact.com, BK = black variant), e.g.:

– MC 1.5/3-ST-3.5 BK for the analog output, – MC 1.5/12-ST-3.5 BK for the power supply, digital I/O, ClipX bus and syn-

chronization of the TF amplifiers,

– MC 1.5/13-ST-3.5 BK for connection of sensors. Other variants, such as with locking clips, are also available from Phoenix Con-

tact, e.g. MCVW 1.5/…, MCVR 1.5/…, FK-MCP 1.5/…

The clamping range of the plug terminals is 0.2 mm2 (AWG24) to 1.5 mm2 (AWG16). If you need to connect multiple wires to one terminal, adapt the wire cross-sections accordingly. Use 10 mm wire end ferrules (without plastic collars) to connect the wires to the terminals wherever possible.

The plug terminals can be protected against interchanging by the supplied coding pins. To do so, plug a coding pin into one of the slots in the device sockets and remove the lug of the corresponding connection on the plug terminal.

6.2 Shielding and grounding design

The supply voltage connection, as well as the signal and sense leads, must be installed in such a way that electromagnetic interference does not adversely affect module functionality (HBM recommendation: “Greenline shielding design” – see http://www.hbm.com/Greenline). Always connect the cable shield by the shortest possible length to the plug terminals and, as far as possible, lay the shield flat at the control cabinet inlet with shield connection clamps, e.g. type SKS 8-SNS35 – 3062786 from Phoenix Contact – see illustration of shield clamp.

Fig. 7: Shield clamp for flat contacting of cable shields (example)

Double-shielded connecting cables, e.g. for sensors

We recommend using HBM cable Kab 7.5/00-2/2/2 wherever possible. The cable is double-shielded and low in capacitance. When using double-shielded cables, connect the outer shield only to the connection for the housing (ground

symbol , labeled “Outer cable shield” in the connection diagrams), not to one of the GND connections ( ). In the case of control cabinets, also lay this shield

contacting on the cabinet – see illustration of shield clamp. Connect the inner shields of the sensor cables to the connection labeled “Inner cable shield” ( ).

Use the shortest lines possible for the connections. Applications in areas with potentially explosive atmospheres are exceptions.

There connect all cable shields to the potential equalization connection.

Single-shielded cables

Connect the shields of single-shielded cables to the connection for the housing

(ground symbol , labeled “Outer cable shield” or “Cable shield” in the connection diagrams), not to one of the GND connections ( ). In the case of control

cabinets, also lay this shield contacting on the cabinet – see illustration of shield clamp.

Grounding

Important: You must ground the support rail on which you mount the ClipX. If you want to mount the ClipX in a different way, such as on a wall, you must ground the housing by way of the mount.

For each ClipX you must provide a power output of 5 W plus the power required for analog and digital outputs. Use an appropriately dimensioned cable for the supply voltage to avoid an excessive voltage drop when operating multiple devices. We recommend using wire end ferrules and a cable cross-section of

1.5 mm2 (AWG16).

6.6 Connecting transducers

Important: Refer to the information on the terminals (“Available con-

nections and LEDs” on page 24) and on cable shielding (“Shielding and grounding design” on page 23).

The signals of the connected sensor or signal are digitized by the ClipX at

19.2 kHz. You can view various signal processing data values in your browser:

• the field value, i.e. the input signal,

• the ADC value, i.e. the signal of the A/D converter in digits,

• the filtered ADC value, i.e. the signal of the A/D converter based on your

selected filter, also in digits,

• the gross signal, i.e. the signal after zero balancing and scaling,

• the net signal, i.e. the signal after taring.

The taring stage is located in the signal path after the gross signal, and only effects the net signal. You can use the tare function, for example, to record the content and total weight of a container or hide the initial load for a force measurement.

With Invalid Signal Value you can specify in your browser which value you want to display and output if the signal is "invalid" (Amplifier menu). For test purposes, you can also define and output a Test Signal Value via your browser.

If you want strain relief for the sensor cable, you can use the included shield connection clamp ME-SAS MINI - 2200456 from PHOENIX. Insert the rigid pin

into the connection for the outer cable shield ( ). Then attach your cable by the clamp. You can order more clamps from HBM by quoting 1-CON-A1023.

You cannot use transducers with TEDS when using Zener barriers.

Use cable KAB 7.5/00-2/2/2 and safety barriers 1-SD01A from HBM to connect transducers in areas with potentially explosive atmospheres to the ClipX (measuring circuit type Ex II (1) GD, [EEx ia] IIC). The connection resistance of the sensor (or of multiple parallel configured sensors) must be between 80 and 5000 Ohms. The maximum line length is 100 m.

6.7 Use TEDS

When the ClipX is powered up, or a sensor is connected, the information in the TEDS module is read and the ClipX is set accordingly (sensor type, scaling, bridge excitation voltage, etc.).

You can use transducers with both 1-wire and zero-wire TEDS (TEDS module in the sense lines). If both TEDS connection variants are installed in the transducer, only the 1-wire module is used.

Specifying usage

You can choose between three TEDS usage variants via your browser's TEDS menu:

1. Ignore TEDS.

2. Use TEDS, if installed.

3. TEDS required.

In the third variant, an error is signaled if no TEDS is found, or cannot be set as specified.

On starting up the ClipX (power on), the analog output initially has a high output resistance. After initializing, the status of the settings is determined in the Start parameter set.

The factory default setting is: Output deactivated, gross signal as input (source), zero value 0 V, scaling 0/0 and 5/5, value in case of “invalid” signal 0 V and test signal 0 V (both inactive).

Value in case of error

Which value is outputted depends on whether you activate the value in case of an “invalid” signal or not. Make the setting via the ClipX web server in your browser.

1. Value in case of “invalid” signal active (switch in browser on the right and

red) If the input signal becomes invalid, or the output signal would be outside the

range of ±11 V or less than 3 mA or greater than 21 mA, the specified value is outputted.

2. Value in case of “invalid” signal not active (switch in browser on the left and

gray) The highest or lowest possible value is outputted depending on the signal

(±11 V, or 3 mA or 21 mA).

6.10 Using multiple ClipX devices, ClipX bus

You can transfer one measured value with status from each of up to five other ClipX devices over the ClipX bus to a ClipX and then capture them simultaneously with the values of that device. The connections use line topology. The maximum cable length between two devices is 30 cm.

Interconnect the CxA terminals and CxB terminals respectively of up to six devices. Lay the lines from the first device to the second, from the second to the third device, etc. (line topology). The ClipX bus GND connection is additionally required. The CxA and CxB lines must be twisted and shielded. See also “Available connections and LEDs” on page 24, “Synchronizing multiple

6.11 Synchronizing multiple ClipX CF amplifiers

You should synchronize multiple ClipX devices that supply sensors with carrier frequency (CF) so that the carrier frequency measuring amplifiers do not interfere with each other. This will prevent crosstalk between adjacent sensor cables, resulting in disturbance to measurements. If you are using only sensors with direct voltage (DC) amplifiers, no synchronization is necessary.

To synchronize, interconnect the Sync terminals of the devices and the ClipX bus GND terminals, unless you have already connected the latter to transmit measured values. Lay the lines from the first device to the second, from the second to the third device, etc. (line topology). The cable must have twisted-pair wires, and be shielded. The ClipX bus GND and Sync lines must be twisted and shielded. See also “Available connections and LEDs” on page 24, “Using multiple ClipX

6.12 Signal phase delays within the ClipX and over the ClipX bus

The various modules in the ClipX are combined into a number of groups, each with fixed cycle times. This makes it easier to calculate the total phase delay of a signal. The following diagrams indicate the phase delays of the various groups as well as any potential additions you might need to allow for the hardware of inputs/outputs. To calculate the maximum phase delay of signals running through more than one group, such as min/max values obtained from calculated channels, simply add together the phase delays of the respective groups.

Pay attention to the sequencing of the analysis within a group. If source signals are formed only later in the group, this will double the phase delay until the result is available.

Phase delays of A/D converter plus digital filter

Some filter frequencies are only possible with a DC amplifier, and are identified accordingly. The bandwidth with DC and the digital filter switched off (Filter OFF) is 3800 Hz. The filter phase delay is then 0 ms, meaning the phase delay of the A/D converter with no filter is 260 μs.

These signals can also use other sources. The phase delays of the source signals must then be

If the analog output is to output a value from this group, you must add on 52 μs. If you are using

a source from a different group, you must add the phase delay of the source signal to the 52 μs.

Some signals might also have sources from other groups. For example, the analog output might deliver a signal from the ClipX bus. In these cases,you must add the phase delay of the source signal's group in order to get the total phase delay:

Example 1

Phase delay from input, e.g. 10 V, 20 mA or DC full/half bridge, to analog output (10 V) with a Bessel filter at 1 kHz:

• A/D converter (ADC) plus filter: 260 μs

• Analog output: 52 μs

Added to this is a jitter of up to 52 μs, as the A/D converter only starts a new conversion every 52 μs. So the total phase delay is 742 … 797 μs.

• Digital output: max. 250 μs response time

Added to this is a jitter of up to 52 μs, as the A/D converter is not synchronized with group 1. In the best case, a value is available at the start of the analysis in group 2 and can be outputted directly at the digital output for example. So the total phase delay is 940 … 1992 μs.

Phase delay of a value from the ClipX bus via a limit switch to a digital output.

• ClipX bus: 1 ms

This results in a total phase delay of 2.3 ms. However, you must add the phase delay in the device that places the value on the ClipX bus in order to get the time from the sensor until a response occurs.

7 Starting up the ClipX

The first section of this chapter explains the general power-up and operating behavior of the ClipX following a successful installation. Then the steps required to put the ClipX into operation are explained. For initial start-up, you should connect the ClipX via Ethernet to a PC. The description of operation via one of the fieldbuses can be found in chapter “Operation via fieldbus” on page 113.

If you want to operate multiple ClipX devices, you should first connect each ClipX device individually to a PC and perform a basic configuration (e.g. IP address and Name). Then read the section headed “Synchronizing multiple ClipX CF

amplifiers” on page 54 so as to avoid interference between the

devices.

7.1 Power-up and operating behavior

When the ClipX is powered up, all the inputs and output remain at 0 or 0.0 V as appropriate. The start parameter set is loaded and activated first (= initialization). As soon as the ClipX has initialized, the outputs are set to the preset or calculated values (factory setting for the digital outputs: 0, not inverted). If the analog output is inactive, the output has a high internal resistance. If the source signal for the analog output is invalid, the specified value in case of an invalid signal is outputted (factory setting 11 V but disabled).

The digital inputs and outputs and the calculations are updated at1000 Hz. The signal at the analog output is updated at 19.2 kHz. If the source signal has a smaller rate of change, the value is outputted multiple times. Values are transferred from synchronized ClipX devices at a maximum of 1000 values per second, so with six connected device you get 6000 values per second. The maximum time delay between the ClipX values transmitted over the ClipX bus is 1 ms.

Up to three clients (PCs) can connect to a ClipX; any further connection is then rejected.

Page 66

Starting up the ClipX

Important: Some browsers make more than one connection. In this case, the number of possible additional connections is reduced.

See also “Using parameter sets” on page 94.

7.2 Connecting a web browser to the ClipX

Preparing to connect

You have two options for connecting to the ClipX:

1. You are using the ClipX's default settings (DHCP, automatic address assign-

ment) a) Make sure that your PC is also using DHCP (Get IP address automati-

cally) – see also “Set Ethernet address of PC” on page 69.

b) Connect your PC either directly to the ClipX or connect your PC and the

ClipX to your network or switch.

c) After connecting, wait about one minute for the ClipX and PC to set their

addresses before connecting.

2. You are using the ClipX's fixed IP address (192.168.0.234, from firmware

2.0) a) Enable the ClipX's fixed address as described in the section headed

“Resetting Ethernet network settings (DHCP), enabling fixed IP address” on page 72.

b) Make sure that your PC's IP address is in the same network segment

(192.168.0.x, where x is a number between 1 and 254 other than 234) – see “Set Ethernet address of PC” on page 69.

c) Connect your PC and the ClipX by an Ethernet cable. In very rare cases,

you will need an Ethernet cross cable for this. Normally the PC will adapt automatically to the cable.

64 A04643_04_X00_00 HBM: public ClipX

Page 67

Starting up the ClipX

Important: The transfer of commands and data is not encrypted or secure (no https). So you should only operate the ClipX in an internal network with no connection to the Internet or – if an Internet connection is essential – connect via a VPN tunnel.

If you want to use multiple ClipX devices, first connector to each individual ClipX and assign a unique device name (or a fixed IP address) through your web browser. This will enable you to identify the individual ClipX devices later, otherwise (depending on the connection method you use) it will not always be possible to distinguish between them.

Connecting

1. Launch your web browser. The latest versions of Firefox, Chrome and Microsoft Internet Explorer (ver-

sion 11 or higher) are supported and have been tested by HBM.

2. Enter ClipX/ or http://ClipX/ or http://ClipX.local in the address bar. Enter

192.168.0.234 if you are using the fixed (static) IP address of the ClipX – see “Resetting Ethernet network settings (DHCP), enabling fixed IP

address” on page 72.

3. The start screen (Login) with User Management is displayed. From it, select your user level or the Home menu.

Important: Do not use https; only http.

If you have already changed the device name, you must enter the new name in place of ClipX. If you have forgotten the name, try one of the alternative options for example.

Click on and the SYS LED on the ClipX you are using will flash red/green.

ClipX A04643_04_X00_00 HBM: public 65

Page 68

Starting up the ClipX

You can make two connections to the ClipX's web server simultaneously. Additional connections are also possible, e.g. via OPC UA.

The ClipX only uses IPv4; IPv6 is not supported.

Finding HBM devices in the network under MS Windows

If the Java Runtime Environment is installed on your PC, you can download the "HBM Device discovery" Java program from the HBM ClipX web page (https://www.hbm.com/ClipX) and unzip it. The program finds all ClipX devices in the network, regardless of their address. Using the context menu for a device (by right-clicking) and choosing Configure network setting you can change the Ethernet settings, e.g. set an IP address or connect to the device (Open

web page).

Alternative options

If the method described above does not work or is not possible, in Windows 7 or higher you can try the following (detect via UPnP):

1. Open Windows Explorer.

2. Click on Network.

3. In the Other devices section you should see the ClipX device (with the device name, factory default ClipX) after a few minutes.

4. Double-click on the icon.

If you know the device's IP address, you can also type it in your browser's address bar, e.g. http://192.168.0.234.

Android

Install one of the following apps from the Google Play Store if you want to connect the ClipX using Android:

https://play.google.com/store/apps/details?id=com.hbm.devices. scan.ui.android

https://play.google.com/store/apps/details?id=com.tjjang.upnptool https://play.google.com/store/apps/details?id=com.melloware.zeroconf

The apps use different connection methods – see also “No device found?” on

page 67.

66 A04643_04_X00_00 HBM: public ClipX

Page 69

Starting up the ClipX

Linux

Under Linux you can also type one of the following lines to call up a list of ClipX devices and their IP addresses or MAC addresses respectively and enter them in your browser:

$ nmblookup clipx

$ avahi-browse --all

Which line works is dependent on which method (NetBIOS or Bonjour) you are able to use, i.e. what software is installed on your PC.

7.2.1 No device found?

If no connection is made, there may be a number of reasons.

General reasons

• Is the device actually on (connected to the power supply)?

• Is the system LED on the ClipX lit? See also “Health-Monitoring, LEDs” on

page 26.

• Is the interface cable connected?

• Have you enabled the correct interface or correct interface adapter on the

PC?

Problems with the interface

• Are you using the correct Ethernet cable?

Use an Ethernet switch with a standard cable or a direct connection by a cross cable.

• Is your Ethernet switch operating correctly?

If you are not operating any other devices on the switch with which you can check the function, try to set up a direct connection between the PC and the measuring device.

• Have you waited long enough for the PC to specify its address?

If the PC cannot find a server in the network, the search for the server looks in the DHCP setting (Obtain an IP address automatically) first of all. (The

ClipX A04643_04_X00_00 HBM: public 67

Page 70

Starting up the ClipX

icon for the interface in the Windows 7 tray indicates the search, but the icon might only appear if it is configured to do so. In Windows 8 and higher it is no longer displayed.) It then takes about 30 seconds before an automatic address or the specified alternative address (if any) is set. No device is found during this time.

• Is it possible that your firewall is blocking the connection?

Try deactivating your firewall or open the following ports:

• For communication with the device via a browser, TCP ports 80 and

8081 are required.

• Different ports are required to locate the ClipX depending on the variant.

For UPnP TCP 80 and UDP-Multicast at IP address 239.255.255.250 (sending and receiving) with port 1900, for NetBIOS UDP 137, for Avahi or Zeroconf (similar to Bonjour) UDP-Multicast is required at IP address

224.0.0.251 (sending and receiving) with port 5353.

• If a WLAN is also active with your PC, test whether the device is found when

you temporarily switch off the WLAN (only for the time of the scan). With some WLAN configurations, problems can occur if multiple Ethernet ports are enabled.

• If your PC has several Ethernet interfaces, try deactivating all other Ethernet

interfaces.

• If you are using the device in a large network, contact your network adminis-

trator. There are a series of options in managed networks to limit or completely prevent data transmission between the individual nodes. Administrative access control settings may therefore by needed here.

Notes

• In Windows XP only the name resolution under NetBIOS is available.

• For name resolutions via NetBIOS, you should only ever connect one ClipX

as long as you have not changed the device names.

• UPnP is only available as from Windows 7.

• Avahi or Zeroconf (similar to Bonjour) is only available if a corresponding

service, such as Bonjour print services, is installed.

7.2.2 Possible cases and their effects when connected via Ethernet

When connecting between the PC and ClipX the following cases may arise:

1. No server in the network, the PC has no address (DHCP is used), and the ClipX is likewise set to DHCP (factory default setting).

When using Windows XP or higher, temporary addresses are automatically assigned by the PC (APIPA), the ClipX connection can be made.

2. No server in network, PC has no setting or is using DHCP, the ClipX has a fixed address

No connection can be established with this combination.

3. No server in the network, PC and ClipX have a fixed address A connection can normally be made only if the addresses of the PC and

ClipX are in the same network segment and both are using the same subnet mask.

4. DHCP server in network, PC has a fixed address or uses DHCP, the ClipX has a fixed address.

A connection can normally be made only if the addresses of the PC and ClipX are in the same network segment.

5. DHCP server in network, PC and ClipX are using DHCP The connection can be established.

7.3 User Management

After connecting via the browser, you are initially at the Operator user level (Symbol ). Click on the icon at the top right of the window to select a different user level: Maintenance (Symbol ) or Administrator (Symbol ). User management enables you to restrict access to the ClipX menus through a

browser. The default setting is for no password to be set and you can switch directly to a different user level. But you can set a different password for both the Maintenance and Administrator user levels, thus restricting access to the settings.

At the Operator and Maintenance user levels, only the Home and Visualiza- tion menus are accessible by default. At the Administrator user level all setting menus are accessible.

If no input is made at the Maintenance or Administrator user level, the user level is reset to Operator after 30 minutes. The user level is also reset when you close your browser and reconnect.

Forgotten your password? You can temporarily disable user management by pressing and holding down the Reset button on the front of the ClipX while logging in or changing a password (any password is accepted, including a blank password field). You will normally need a second colleague to press the button while you are logging in. See also “Available connections and LEDs” on page 24.

All characters are allowed, including special characters. For security reasons, you must enter the password twice before you can activate it with

CHANGE PASSWORD.

Specify at the Administrator user level the menu items to be accessible at the Maintenance level by checking the relevant checkboxes. At the Operator user level no changes can be made; only the Home and Visualization menu items can be displayed.

You can reset both passwords by loading the factory default setting in the Device menu (Without network settings is sufficient).

When connecting via the fieldbus interface, you can enable the Maintenance or Administrator user level directly for the browser by one command, without entering a password. When doing so, you must specify a time for which the password deactivation is to apply, up to a maximum of 24 hours. You can also disable the selected user level prematurely, or extend the time period. The active user level is also available in the browser as from the time of switching and for the specified period of time, and is displayed accordingly. The setting via the fieldbus has priority over any setting made in the browser. See “Object dictionary” on page 149.

For the connection via the fieldbus itself you do not need a password; all functions are always accessible there.

7.4.1 Assistant to measure sensors

The Assistant menu option will help you to measure your sensor if you do not have a calibration protocol or you want to measure the sensor when installed. Before measuring, set the sensor type in the Amplifiers menu to enable the ClipX to perform measurements. Also specify a suitable low-pass filter, e.g. 10 Hz for static measuring, so as to obtain the most stable possible measure-

76 A04643_04_X00_00 HBM: public ClipX

Page 79

Starting up the ClipX

ment values. For dynamic measuring, you must select the filter matching your signal frequencies and process.

The assistant provides two measurement variants:

1. Mode: Static Two points are measured: the value with the sensor under no load and the

value with the sensor under load (force/pressure/torque, etc.). The measurement itself is performed over a period of about 6 seconds with the filter set in Amplifiers. The calculated mean value and the (sample) standard deviation are displayed both during and after the measurement process.

2. Mode: Dynamic This mode is suitable when you are not able to apply a constant load

(force/pressure/torque, etc.). The peak values are calculated over your measuring time and displayed.

You can either enter the physical value of the load manually or import it over the ClipX bus or via one of the interfaces.

Procedure

1. Select the Mode.

2. Choose whether you want to enter the reference values manually or import them.

3. Either enter the reference values (the unit will be applied from the Amplifiers menu, though you can change it here) or specify the signal source for the reference values (e.g. from the ClipX bus).

4. Start the measurement. In static measuring mode, the sensor is first measured under no load. Then

you must apply a load to the sensor and start the second measurement. You can stop dynamic measuring mode when the minimum and maximum values have been reached at least once.

5. When the measurements are complete, you can either accept the measured values and click APPLY or start a new measurement cycle.

The already measured values will then be set off against the new values (averaging).

The window closes when you click APPLY.

7.4.2 Calculation functions

Specify your calculations by choosing Calculated Channels from the menu. You can create up to six calculations, and output up to six result channels plus eight digital flags (the 6x6-matrix calculation already delivers up to six result channels). Each calculation is executed 1000 times per second.

Procedure

1. Click on one of the six lines at the top of the window under Function Blocks.

2. Select one of the calculation functions under Select Function Type.

3. Select the inputs or numerical values you want. If you need more constants than those already available (internal constants), you must first specify the number at the bottom of the window in the User-defined Constants area. You can create up to 10 custom constants and assign them suitable names. The formula for calculating the respective function indicates how the variables x1, x2 etc. will be used. Check that all variables have corresponding

values, even if they are not used. Otherwise, a multiplication by 0 for example might make the preceding variable practically ineffective.

4. Select the channel in which you want the result(s) to be outputted. For digital signal, eight flags (bits) are provided.

5. Give the result channels informative names. Flags cannot be renamed.

Most calculations have only one or two outputs; the logic function NOT has 2 times 2 outputs; for the 6x6-matrix up to six outputs are possible. If the value is outside the displayable number range, NaN (not a number) is outputted. If one of the input values is invalid, the result is also flagged as invalid, though the calculation is normally performed and the result outputted. For more information on this refer to the relevant calculations.

Click on DELETE below the calculation formula to be able to assign a calculation a different function type. To avoid accidental deletion, the

button changes to CONFIRM DELETE, and you have to click it again.

Sequence of calculations

The sequence of the functions at the top of the window decides when which calculation is made. It does not matter which of the six function blocks you define

the calculation in. Change the sequence using UP or DOWN below the calculation formula.

7.4.2.1 6x6 Matrix

Calculates six output signals from up to six input signals by means of a matrix. For x1 to x6 Select the input channels and for y1 to y6 select one of the six available calculated channels in order to output the relevant result channels.

You can use the calculation to compensate for the crosstalk of a multi-component force transducer in the output signal. Enter only the coefficients (axx) in the dialog table. Use 0 for unused coefficients. For example, if you do not need input x6, set every ax6 (a16 to a66) to 0.

If one of the source signals is invalid, all the output signals will become invalid as well.The calculation will nevertheless be performed and the result exported.

7.4.2.2 Tolerance window

The tolerance window combines several functions: Acquisition of minimum, maximum, peak-to-peak and arithmetic mean and monitoring of exceeding/undershooting a limit for a definable period of time. You can also determine the value of another channel when an extreme value is reached.

Note: If you do not want to use any channels to define the level values for level monitoring, first define the levels with User-defined Constants (Calculated Channels menu at bottom).

ClipX A04643_04_X00_00 HBM: public 79

Page 82

Starting up the ClipX

Procedure

1. For Input, enter the channel to be monitored.

2. For Start with define a digital signal that starts the functions on a rising edge. All output signals (min, max, etc.) and the flags for level monitoring are reset at the start.

3. For Stop with define a digital signal that stops the functions on a rising edge. All output values (min, max, etc.) and the flags for level monitoring are frozen at the stop.

4. If you want to determine the value of another channel when a (new) minimum or maximum is reached, specify the channel for Hold Channel.

5. If you want to use the monitoring functions, specify the Threshold High and/or the Threshold Low.

6. Finally, specify the outputs and flags for the desired results.

Function

After the start, all values and the flags are first reset. Then the signal at the Input is checked for minimum and maximum and the oscillation bandwidth and mean value are calculated. The mean value is calculated across a maximum of 100,000 values (100 s). The amount of time between a start and the corresponding subsequent stop is measured as Duration in milliseconds. The Input is also monitored for exceeding or undershooting the high and low thresholds. If the relevant limit is exceeded or undershot during the runtime, the corresponding flag is set. If you specify a channel for Hold Channel, its value when a minimum or maximum of the channel specified for Input occurs will be retained until the next occurrence of an extreme value (Captured at Min or Captured at Max). At stop, all the output values and flags are frozen, which means they remain in their final status.

If the Input source signal becomes invalid, the peak values and the mean value are captured and marked as invalid. The Duration output is not influenced by this. The Hold Channel is not checked for validity.

If the Duration (time between start and stop) is more than 100 s, the mean value is no longer updated and is marked as invalid.

7.4.2.3 Peak with capture

This calculation determines the minimum, maximum or oscillation bandwidth of a signal. You can also have the value of another channel (Hold Channel) determined when an extreme value is reached (output signal Captured Value). You can tell by the falling edge of the peak flag (about 1 ms after detection of a new peak value) that a new peak value has been found. As long as the measured value continuously rises (in case of maximum) or falls (in case of minimum) the peak flag is High (1).

Select the desired function and if necessary create a digital input to reset the value (level-controlled, in case of High (1), Reset by). Set Reset on to Low level to reset as long as a Low signal (0) is active.

You can use the Reset by input to capture no new (peak) value at specific times, leaving the current one instead. This is equivalent to temporarily deacti- vating the memory function. The capture takes place level-controlled at High (1), unless you are using Hold on: Low level, capture takes place as long as a Low signal (0) is active.

If the source signal Input is invalid, no analysis is carried out. If the signal of the Hold Channel is invalid at the time of a peak value, the value is stored, but is

marked as invalid.

7.4.2.4 Trigger

The calculation monitors whether an analog signal exceeds and/or falls below a limit value. You can monitor two limit values with the function. Use the hysteresis to prevent signal noise from generating multiple trigger pulses. As soon as a limit value is exceeded and/or undershot, a pulse (lasting 1 ms) is outputted on the trigger flag. As long as the signal remains within the hysteresis, no further pulse is triggered. The Hysteresis is below the limit value in the case of Above

threshold and above in the case of Below threshold. In Above or below threshold mode the hysteresis is both above and below (example 2).

If the source signal is invalid, no pulse is generated. The values for limit value and hysteresis are not checked.

7.4.2.5 Automatic mean

The calculation filters an easily usable signal from a severely fluctuating or noisy signal by using a specific segment of the signal curve to compute a mean value. This enables you to reduce the impact of overlaid interference. You can also define a range in which the signal is averaged and used as the zero value for further measurements.

You have two options in each case for starting measurement and zeroing:

1. By a limit value.

2. By a digital signal.

You can also combine the methods, i.e. start measuring a mean value, min/max etc. by way of a limit value and start zero measurement by a digital signal.

If you do not want monitor the start and stop of the calculation via a digital signal, set Enable by to 1 (internal constant) and Start on to High level for example. The calculation is then performed whenever the conditions (Threshold or

Start Measure/Start Zeroing with) are met. Maximum Value, Minimum Value, Peak-to-Peak and Mean are the values

determined during the measuring time via the signal at the input. The Offset is the mean value over the Zero Tracking Time. The Status contains an identifier for the current status of the calculation – see diagram and table below. The Measured Value is continually updated throughout the time (current measurement value).

7.4.2.6 Physical work

The calculation determines the (physical) work over a specific period from the two quantities of force and distance (or for example torque and angle of rotation). The force must act along the distance. You will need the measurement values of a different channel for the calculation, e.g. via the ClipX bus.

For Start with define a digital signal that starts the function on a rising edge. At the start, all output signals are reset to zero. Then the work done since the start is calculated (∫ F(s) * ds where F = force and s = distance) and outputted in Work. For Stop with define a digital signal that stops the calculation on a rising edge. At stop, all output signals are frozen.

Normally, the Work value will steadily increase during the runtime. But if one of the source signals – that is, either the force or the distance for example – becomes negative, the work decreases again. In this case Work Max (maximum work value between start and stop) will have a different value than Work. Additionally, the maximum force and distance are always calculated and outputted during the runtime.

If one of the source signals is invalid, all the output signals will become invalid as well. The calculation is aborted in this case, and you have to restart it with a new start signal.

7.4.2.7 Adder, Multiplier and Divider

Multiplies up to four source signals and adds together up to four of those terms in its adder/multiplier function. You can use constants as source signals to multiply channels by a factor (e.g. -1 for subtraction). Set inputs for terms you don't need to 0 (internal constant); set all others to 1.

In the divider function two terms are divided. The dividend adds together up to three terms, for each of which 2 inputs are multiplied; the divisor adds together up to three inputs. Set inputs for terms you don't need to 0 (internal constant); set all others to 1.

Output = dividend/divisor

In addition to the "normal" division, a modulo division is carried out. This modulo division checks how often the divisor is fully included in the dividend and determines the Residual z. When you divide 11 by 4, for example, the 4 is included twice in 11, and 3 is produced as the Residual z (2 x 4 = 8, 8 + 3 = 11).

If one of the source signals is invalid, all the output signals will become invalid as well.The calculation will nevertheless be performed and the result exported.If the result is outside the number range, NaN (not a number) is outputted.

7.4.2.8 Counter

Counts the edges (rising/falling/both) of a digital signal. Use Start/Stop with to interrupt the count.

Timeout after: If you enter a time greater than 0, after that time the counter is reset if no edge has occurred by then.

With Threshold Value for Flag you can set a flag when a specific count is reached.

7.4.2.9 Cartesian to polar coordinates

The calculation converts two input channels representing the position (x, y) of a point in the Cartesian coordinates system into the corresponding polar coordinates. You will need the measurement values of a different channel for the calculation, e.g. via the ClipX bus. The calculation results in two output channels: one with the angle values (θ, theta) and one with the radius values (r). The value range for the angle extends from -179.99° to +180°. Multiply the value by π/180 as necessary to get the radian measure (rad).

Fig. 44: Example for coordinates transformation

If one of the source signals is invalid, all the output signals will become invalid as well.The calculation will nevertheless be performed and the result exported.

7.4.2.10 Polar-to-Cartesian coordinates

The calculation converts two input channels representing the position (Radius r, Angle θ = theta) of a point in polar coordinates into the corresponding Cartesian

coordinates. You will need the measurement values of a different channel for the calculation, e.g. via the ClipX bus. The calculation results in two output channels: one with the x values and one with the y values. The angle value must be in degrees (-360° to +360°).

Fig. 45: Example for coordinates transformation

If one of the source signals is invalid, all the output signals will become invalid as well.The calculation will nevertheless be performed and the result exported.

7.4.2.11 PID controller

This calculation implements a PID controller in parallel structure. The PID (Proportional Integral Derivative) controller consists of three elements: the P term, I term and D term. The parallel structure of the controller prevents a wind-up effect. You can limit the output signal via Y

max

and Y

. When one of the values

min

is reached the Min/Max Flag is set. Td is the parasitic time constant at 1/update rate = 1 ms.

Fig. 46: Block diagram of the PID controller

You cannot define the PID controller as a simple P controller. At least one I element must be present in addition (Ti ≥ 0.01 s).

If either the target value or actual value is invalid, the controller stops and the value is marked as invalid. However the output retains the last value. In the case of Enable by: 0 the controller is reset and the value of Y

is outputted. This

input has priority over the Start/Stop with signal.

7.4.2.12 Signal generator

This calculation generates a periodic signal, for example a sine wave. Determine the desired frequency, amplitude and, if applicable, an offset. Signal forms available are sine, square wave, triangle, counter, constant and (white) noise. The signal on Start/Stop with together with Start on determines whether the selected function will be outputted. When Start on: High level) is set, on a Low

ClipX A04643_04_X00_00 HBM: public 91

Page 94

Starting up the ClipX

level (0) the output is stopped and the Offset value is outputted. When the signal switches back to High (1), a new output period begins.

Use 100 Hz (1/10 of the update rate) as the maximum frequency, otherwise the output signal will not be formed from enough points. This results in a distorted curve shape (stairway effect) for a sine wave.

Example: Sine with amplitude 50 and offset 50

The amplitude fluctuates sinusoidally between 0 and 100 at the set frequency. If the result is outside the number range, NaN (not a number) is outputted.

Counter function

At an offset of 0 the counter generates a number between -Amplitude and +Amplitude that is incremented by one each time by the update rate (1000 Hz). Any entered frequency is ignored.

White noise function

The noise signal is generated by a hardware noise source (integrated circuit).

7.4.2.13 Pulse-width measurement

This calculation measures the time between two edges. You can use one or two (digital) channels (flags) as the input. The result can be output as time (seconds or milliseconds) or as frequency (1/s). Specify the same channel for Start with and Stop with, and use different levels if you only want to use one input channel.

Maximum resolution (smallest measurement duration): 1/update rate; at an update rate of 1000/s this is equivalent to 1 ms.

Maximum measurement duration: 600 s. The output becomes invalid and the calculation is stopped if the maximum measurement duration is exceeded. This status is reset by the next start signal.

7.4.2.14 Timer

After a programmable time (Interval), sets the Timer Flag to active and holds the level over the Pulse Length before the level is reset to inactive. If you enter 0 for the Pulse Length, the flag is set to active at least for one update interval (1/update rate = 1 ms). The maximum interval is 200,000 seconds. The Pulse Length should be shorter than the Interval, otherwise the flag will always be active as long as the timer is running. Choose Active Timer Flag to set the

Timer Flag to Low (0) or High (1) when active. Enable by: Depending on the setting of Enable on (High level or Low level),

the timer is only started when the corresponding level applies. In both Single shot and Continuous mode the timer is stopped (reset) immediately if this level

is no longer active. The values at the outputs are deleted, or reset to 0, in this case.

The procedure can be run once only (Type: Single shot) or continually repeated (Type: Continuous) as long as a corresponding signal is active on Start/Stop with.

In the case of single shot and Start on: High level, a positive edge starts the timer and the next positive edge only restarts the timer when the time has elapsed. In continuous mode, the timer starts as soon as a High signal (1) is on Start/Stop with, and immediately restarts at the end of the interval. As soon as no High signal is active any more, the timer is stopped and is only restarted when a High signal is received.

In the case of single shot and Start on: Low level, a negative edge starts the timer and the next negative edge only restarts the timer when the time has elapsed. In continuous mode, the timer starts as soon as a low level (0) is on Start/Stop with, and immediately restarts at the end of the interval. As soon as no low level is active any more, the timer is stopped and is only restarted when a low level is received.

Both the Timer Flag and the current time value (Time) are outputted: 0 when the timer starts, the Interval value at the end of the interval. When the timer is stopped, the interval time is outputted constantly.

7.5 Using parameter sets

You can store up to 10 parameter sets in the ClipX. A parameter set contains almost all the settings of the various menus for Amplifier (sensors), Calculated Channels, Peak Values and Limit Switches etc. It does not include the net- work settings, TEDS usage, the passwords, the visualization, fieldbus and ClipX bus settings and settings for synchronization of the CF amplifiers.

You can also transfer the parameter sets together with the other device settings to your PC. Give the parameter sets names so that you can distinguish them more easily. You can use up to 30 characters per name.

The active parameter set is indicated by ACTIVE, and the start parameter set by BOOT.

on the second line in the browser window indicates that the original settings of the current parameter set are no longer being used. Save the settings to a parameter set so as not to lose them.

Starting up the ClipX

You can save, load and activate parameter sets via the web browser or the fieldbus interface, or activate them only via the digital inputs.

Processing parameter sets

On a new ClipX all the parameter sets contain the factory setting. You can reset a (single) parameter set to those defaults at any time by clicking on FACTORY

SETTINGS in the browser while a parameter set is active.

When the ClipX powers up, all the parameter sets are translated into the relevant binary instructions and stored in the RAM in order to enable quick parameter set changing. Then the start parameter set is activated.

Each parameter set is assigned a check digit (CRC, cyclic redundancy check) in the RAM in order to avoid errors.

It takes just a few milliseconds (<100 ms) to change the active parameter set. However, in the event of a parameter set switch which changes sensor settings, filters or the analog output, the measurement status is set to INVALID for approximately 2.5 seconds so as to suppress transient responses on the outputs. Brief timeouts may also occur on the ClipX bus (SYS LED turns yellow).

7.6 Device storage (Device cloning)

Using the Device storage menu, you can back up all the device settings to your PC or restore them from it. You can also transfer all the settings to another device (Device cloning). All settings are saved in the operation. When restoring, you can choose which settings to restore.

Here you will also find the working standard calibration certificate, the manufacturer’s certificate, the default files for the fieldbuses (PROFIBUS, PROFINET and EtherCAT), possible log files, and the object directory (clipx_OD.csv). A new object directory is generated each time prior to downloading so that it contains the current status. As a result, the download takes several seconds.

You can also upload your own files to this area and download them back to your PC or delete them.

Backing up device settings

Click on BACKUP. The ClipX creates a ZIP file. The file name is composed of the device name, the UUID (serial number) and the current date, e.g. ClipX_009043-20180424.zip. Depending on your browser setting, you are prompted to select a folder, or the file is saved to your Download folder.

Restoring device settings

1. Click on REVERT and specify the file containing the desired settings.

2. Activate all lines whose settings you want to load. To load everything, click

on Select all.

• Network: Contain all the settings of the Ethernet port such as IP

address, subnet mask etc., as well as the settings for time (e.g. NTP) and OPC UA.

• General: Contains the settings for TEDS usage, visualization, ClipX bus

(address and synchronization mode Master or Slave), the number of the start parameter set, and the settings for parameter set switching by the digital inputs (where specified).

• Fieldbus: Contains all the settings of the active fieldbus (only BM40IE

and BM40PB).

• Password: Contains the passwords being used for the user levels in

encrypted form.

• User management: Contains the settings (accessible menu items) of the Maintenance user level.

• Visualization: Contains the settings for the Visualization menu.

• Parameter set 01 … Parameter set 10: Contains the settings of the

specific parameter set.

3. Click on REVERT again.

Saving (uploading) your own files to the ClipX, ClipX memory

Files that you have already uploaded, such as the working standard calibration certificate, are displayed in this area, and you can choose to save the files on

your PC. Depending on your browser setting, you are prompted to select a

Starting up the ClipX

folder, or the file is saved to your Download folder. Select a file and click on

DELETE to remove the file from the ClipX memory.

Choose FILE UPLOAD to upload your own files, such as more calibration certificates, to the ClipX. The file name must not contain any special characters (umlauts) or blanks, only ASCII letters and numbers, dashes (-) and (underscores (_). At least one, and a maximum of 130, characters are allowed. The file extension must comprise two to a maximum of four characters. You can upload any file formats. If the upload did not complete correctly, because of insufficient space for example, the failure is indicated at the bottom of the browser window and any storage space already occupied by the file is freed up again.
