Realtime values

Last modified: 2026-04-29

You can view the realtime data of the devices connected to your bluelog. Realtime values are a live measurement: the data is neither stored nor exported and is only displayed on the web interface.

View realtime values

Prerequisites

• At least one device is installed on your bluelog.

Steps

1. Go to Cockpit > Realtime values.

2. Under Value selection, select the device type(s) you want to display.

   • The active device category is underlined in blue.

3. Select the devices you want to display. Select all to select all devices of a category.

   • Example: “Inverters 1/2” means that two inverters are configured, and you have selected one to display.

4. Under Values, select the values you want to display. The Select all option allows you to select all values of a category.

5. Select View.

The realtime values are listed under Realtime values and can be displayed in the Charts.

Note

Cos phi (also known as cos φ or power factor) is a calculated value.

When multiple real meters are combined into a virtual meter, the cos phi value is calculated based on the following formula:

Variables

• P is the measured active power sum of all phases

• Q is the measured reactive power sum of all phases

• tan^-1 represents the arctangent function

• sgn(Q) represents the sign of Q, so if Q is underexcited it is -1, otherwise it is 1

Any measured values from the individual meters are ignored.

Check communication between bluelog and another device

You can check how well communication is working between the bluelog and a device using the Telegrams received and Telegrams transmitted checkboxes under Values. The transmitted and received telegram counts should match, confirming that commands are successfully sent and acknowledged. A mismatch may signal a device issue or require adjustments to the read delay or timeout settings.

Prerequisites

• At least one device is installed on your bluelog.

• The device is connected via RS485 or Ethernet.

Steps

1. Go to Cockpit > Charts (to display information as a chart) or Cockpit > Realtime values (to display information in a list).

2. If multiple devices are installed, select the relevant device category (e.g., Inverters). You can view multiple categories at once.

3. Select the device(s) by ticking the checkboxes, or choose Select all to include all devices in a category.

4. Tick Telegrams received and Telegrams transmitted under Values.

5. You can view the telegrams in the Chart area. To view the telegrams in the Realtime values area, select View.

6. If the transmitted and received telegram counts do not match, indicating a potential issue, contact Support for assistance.
