Realtime values

Last modified: 26 Feb 2025

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

View realtime values

Prerequisites

• At least one device is installed on your blue'Log.

Steps

1. Go to Cockpit > Realtime values.

2. If there is more than one device installed on your blue'Log, select the device category you want to view, for example Inverters. You can view multiple device categories simultaneously.

3. Select the device(s) you want to view by ticking the checkboxes. Select Select all to select all devices of a category.

4. Select the value(s) you want to view by ticking the checkboxes. Select Select all to select all devices of a category.

5. Select View to display the values. The values will be displayed in the Realtime values area.

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 blue'Log and another device

You can check how well communication is working between the blue'Log 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.

Prerequisite

• At least one device is installed on your blue'Log.

• The device is connected via RS485 or Ethernet

Steps

1. Go to Cockpit > Realtime values.

2. If multiple devices are installed, select the relevant device category (for exmaple 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. Click View to display the telegrams in the Realtime values area.

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