2 The VCM-3 Homepage
2.1 Introduction
The configuration of VCM-3 is done via the VCM-3 Homepage. No software installation required.
The VCM-3 Homepage is divided into three main blocks:
1.
Commissioning configuration: This part is utilized during initial on-site commissioning of a
machine and for later adjustment by remote access if required.
2.
Remote/On-site check of descriptors, time waveforms (input channel/sensor raw signal and
frequency spectra.
3.
Administrative configuration: This part is used by system administrators. Normally this is done
through remote access when the system has been commissioned at the machine.
Please find below an overview of the VCM-3 Homepage.
2.2 Login and default IP address
On first time login to the VCM-3, you may use the following credentials:
Administrator User
A user which has administrator rights on the VCM-3 homepage. All parts of the VCM-3 homepage
can be altered by this user including create and modify users.
Username: vcm_admin
Password: VCM3-CMS-Management

How to connect a laptop to VCM-3 Homepage
1
Change the laptop network settings to match the IP range of the VCM-3. Factory default network
settings of VCM-3 are as follows:
•Netmask (subnet mask): 255.255.255.0
•IPv4 address: 192.168.2.202
HINT!
Brüel & Kjær Vibro recommends that to set the laptop to IPv4 address
192.168.2.199, Netmask 255.255.255.0
Refer to procedure Appendix 4: Changing laptop network connection on how to change network
settings.
2
Connect the laptop to the VCM-3 unit using a LAN cable with one of the RJ45 connectors.
3
Enter the IP address of the VCM-3 in the address field of the browser.
If you connect to a particular VCM-3 for the first time, the browser will prompt you with security
precautions as it does not know the origin of the VCM-3 public certificate.
Accept the risk in order to open the VCM-3 Homepage login page. Use the credentials as described
earlier in this section.

2.3 The Operational Status page
How to inspect the Operational Status page
1
After login the Operational Status page is shown. This page gives an overview of the present
status of the VCM-3. As a general rule the status indicators in the red boxes must have the
status as shown on the screenshot. Otherwise there is a problem with the VCM-3.
The other status indicators are dependent upon the state of the commissioning procedure.
2
If the status indicators in the red boxes shows a different result, try to reboot the VCM-3 and
inspect the Operational Status page again.
1. Reboot the VCM-3 and check if the problem disappears. The reboot activates some repair
facilities.
2. If 1) does not help then make an upgrade of the firmware. Refer to the procedure in
BUM1093 On-site Commissioning manual: Appendix 2.
3. If 2) does not help the VCM-3 has a fault. Exchange the VCM-3 with a spare unit.

2.6 Commissioning –Oscilloscope
Use the Oscilloscope function to view the raw time waveform recorded from each of the sensors while
commissioning. Use the Oscilloscope function to check the sensor connections and that the sensor
provides a valid signal.
For further information please check the On-Site Commissioning Manual.
NOTE!
The intended use of the Oscilloscope function is during commissioning to check the
input channel signal (raw sensor signal). The Oscilloscope function should only be used
with the factory template for commissioning. By using this function with other templates
than the commissioning (factory) template the Oscilloscope the plot could freeze, or the
VCM-3 homepage becomes unresponsive. When this condition occurs, the user usually
has to call up another function on the VCM-3 homepage and then return to the
Oscilloscope view.
IMPORTANT NOTE!
The measurement functionality of the VCM-3 is not affected by this behavior!
All measurement functions of the VCM-3 hardware/firmware continue to run, alarm
states are registered and communication via MODBUS or OPC is maintained.

2.9 Data –View Descriptor Data
All descriptor (measurement) values measured by the VCM-3 can be viewed on this page. A selection
of maximum six descriptor values can be plotted as a continuously updated trend curve.
How to View Descriptor Data
1
All descriptor data can be viewed in the list if “all” is selected in the Descriptor group list.
2
If descriptor groups have been defined in the monitoring template the list may be shortened down
by selecting one of these groups. E.g. a group may have been defined for all descriptors
measured on a gearbox high speed stage or another group may be defined to show all ISO RMS
values in the template.
3
Use the search field to display desired descriptors in the list. Key in more than two letters, to find
desired elements in the list.
4
Use the checkboxes to the left of the list to select descriptors for trend display.
A maximum of 6 can be selected simultaneously.
5
Scroll to the bottom of the list to view the trend curves for the parameters. Display them as an
overlay plot or as a single plot for each descriptor.

2.11 Data –Time Waveform Recording
NOTE!
Usage of this function requires that a minimum of one-time waveform trigger and one
ring buffer have been defined in the monitoring template.
You must have a description of the configured triggers and ring buffers in the actual
template as a help to configure time waveform recording.
This function can be used to initiate an immediate download of time waveform files to a remote server
or the PC running the browser with the homepage. The download format is a .json file.
This can be applied by a diagnostic engineer when a machine fault is suspected.
If the time waveform is downloaded to a server or directly to the PC, a conversion program is required
which can convert the .json file to a format which is compatible with the tools for further analysis.
How to initiate a Time Waveform Recording with download to a remote server
1
Select Trigger remote download
2
Select the Trigger group. The trigger group is defined in the monitoring template and defines
which ringbuffers shall be downloaded when the trigger is activated.
3
Specify the IP address of the Remote Server. A web service on the remote server must be
available to receive the download request from the VCM-3.
4
Enter a Reference ID. This is a free text string used to identify the particular download
5
Specify Timeout (s). The remote server must have responded within the time specfied.
6
Specify number of Retries in case of timeout
7
Specify Delay (s). This is the period of time between retries
8
Click the Trigger button to activate the download

How to initiate a Time Waveform Recording with download to a local PC
1
Select Download locally.
2
Select the Trigger group. The trigger group is defined in the monitoring template and defined
which ringbuffers shall be downloaded when the trigger is activated.
3
Specify if RPC header shall be included in the downloaded .json file. This is used if the files shall
be sent to a remote WEB service
4
Enter a Reference ID. This is a free text string used to identify the particular download
5
Click the Trigger button to activate the download
2.12 Data –One Shot Trigger
NOTE!
Usage of this function requires that a minimum of one time waveform trigger, one ring
buffer and one push job have been defined in the monitoring template.
You must have a description of the available triggers, ring buffers and jobs in the actual
template as a help to configure the one shot triggers.
The One Shot Trigger is activated once, and then forgotten by the VCM-3. Cyclic triggers can be
defined via the monitoring template.
A manual arming of a One Shot Trigger can be configured via this function. Once the defined trigger
condition is fulfilled the raw data in the ring buffers linked to the trigger setup is downloaded to the
remote server.
The One Shot Trigger is a tool which can help the diagnostic engineer to get data in addition to the
more regular data specified in the monitoring template and to get data under a certain machine
condition.
The data which is recorded as result of the defined trigger is downloaded to the server(s) specified in
the selected Job. This is a so-called push job and must be part of the current monitoring template.
The push job contains the IP address(es) of the server(s) which shall receive the data.
If data are pushed to a server a web service on the remote server must be available to receive the
download request from the VCM-3.
