VCOM

Last modified: 26 Feb 2025

You can sync one blue'Log with a single VCOM system. The following graphic provides an overview of the functions under Plant > VCOM.

Note: in VCOM and blue'Log, the terms plant and system have the same meaning.

Item	Name	Details
1	Plant name	Your VCOM system's name is automatically retrieved upon connection and can only be changed within VCOM.
2	Plant key	Enter the 5-digit VCOM system ID. In VCOM, this is located under the System configuration > System > Technical data > System key.
3	Cancel registration	Disconnect your blue'Log from VCOM. Example: You want to switch VCOM systems, or your blue'Log is defective and must be replaced. Note that if your blue'Log is currently offline, it will automatically disconnect from VCOM once it is back online.
4	Check connection	Verify VCOM accessibility
5	Transmission interval	Choose data transmission frequency: 5 minutes, 15 minutes, 1 hour, or disable transmission.
6	Historical data	If data is missing in VCOM, specify the relevant dates here. Example: You install a blue'Log in your system, activate VCOM 6 months later, and want to retrieve the data from the past 6 months.
7	Initiate resend	Retrieve historical data after setting the desired dates
8	Remote device access	You can access the user interface of some devices with their own web-based user interface via the blue'Log. See Connect to a remote device in VCOM.

Connect a blue'Log to a VCOM system

2. Select Register.The system name will be retrieved from VCOM and appear under Plant name.

3. Select a transmission interval and select Save.

4. Your blue'Log should now be connected with VCOM. To verify this, select Check connection. A green check mark will appear if the connection exists.

Connect to a remote device in VCOM

Prerequisite

• This feature is available only for certain devices. Refer to the Compatibility check to verify if your device supports Remote device access.

Steps

1. Set up the device, for example under Devices > Meter > Add new meter.

2. The device IP address will appear under Installed devices. 

3. Activate the Remote device access toggle under Plant > VCOM > Extended access. This option will only be visible if your device supports this feature.

Troubleshooting: No network connection to VCOM

Problem

Data​ transfer to VCOM fails or the device is displayed as offline in VCOM

Solution

Confirm that:

• The data logger is ready for operation. The top and middle LEDs should light up. If the bottom LED lights up red, the internet connection is disrupted.

• The data logger is connected to a router via an Ethernet cable

• The IP configuration is correct. If it is incorrect, this affects the following parameters:

  • IP address

  • Subnet mask

  • Gateway address

  • DNS server

Check the IP configuration via the blue’Log display

1. Press OK to select a user and log in using a 4-digit code.

2. After a successful login, the network configuration is displayed. Use the Left arrow button to select and modify the settings as needed.

​Check the IP configuration via the browser

1. Enter the IP address of the data logger in the browser address line. This is shown on the display start page. Alternatively, use the hostname of the device. This consists of the last 8 digits of the serial number.

2. Log in with your username and password.

3. Navigate to the network settings under System > Ethernet and check the IP configuration.

4. Check the remote connection in VCOM under Plant > VCOM.
