Digital output

Last modified:

Digital outputs allow you to control activities that can have two states, e.g. turn something off or on. You can activate digital outputs from the bluelog and Multi I/O MX add-on modules.  A digital output stays active if you reboot the software and if the activation signal is still active. Only a hardware reset or disruption of the power supply to the bluelog will deactivate the digital output.

Add a digital output

Prerequisites

  • Your bluelog is connected to the network.

  • The basic configuration of your bluelog has been completed.

  • All bluelog updates have been performed. See Update.

  • Add-on modules, if required, are connected. See Add-on modules.

Steps

  1. Navigate to Devices > Digital output > Manage digital outputs.

  2. Select the Plus to add a new digital output.

  3. Enter a name for the digital output.

  4. Select the interface and logic level (settings depend on the connection type).

  5. Choose the signal that activates the digital output.

    • If selecting a SCADA interface, the register is assigned automatically.

    • If selecting a pulse or digital input, define the activation settings under Signal. See Activation signals for digital outputs.

  6. Select the Save icon to save the settings.

  7. Confirm that the digital out put is active by checking the State column:

    • check mark Check mark: activated

Activation signals for digital outputs

Digital outputs can be activated and deactivated in the following ways:

Method

Description

Manually

A Power button icon appears on the right side of the configuration, allowing you to manually switch the digital output. 

SCADA interface

The output can be switched via a SCADA address (SCADA interface License required). Every digital output is automatically assigned to a Modbus register by the system. For more information, see the SCADA Interface bluelog Neo license data sheet.

SCADA signal requirements

  • The SCADA interface must send a signal at least once every 60 seconds.

  • If the bluelog does not receive a signal after 60 seconds, the digital output will switch off.

  • The Client ID/Slave ID for the digital outputs is 98. 

Digital input

  • Digital outputs can be switched depending on a digital input.

  • All free digital inputs from the bluelog and the connected Multi I/O add-on module can be used.

  • Digital inputs that are already configured for the following functions can not be used and will be grayed out:

    • Energy meter S0, Status device, and Power control

Pulse

Digital outputs can be switched with pulses from 0.5 to 5 seconds (user-defined)
