Block Alarm memory basic

This control element shows at a glance whether an alarm or a warning is pending or has been pending – for instance from a water detector or a fault message of the heating. It counts the alarms and warnings, keeps a list with date and time and can be reset once the cause has been dealt with.

Operation

1. Alarms: the red circle shows how many alarms have been counted since the last reset. At 0 it is not shown.
2. Warnings: the orange circle counts the warnings in the same way.
3. State: the field in the middle has the colour of the state:
   • green: all in order,
   • red: an alarm is pending,
   • yellow: an alarm was pending and is gone again, but has not been reset yet,
   • orange: no alarm, but a warning is pending.

As a circle (basic screen) the whole circle has the colour of the state, the number of alarms is shown in the middle. A tap on the element opens the dialog.

The dialog

1. Messages: every alarm and every warning with date and time, the newest on top. A (red) stands for an alarm, W (orange) for a warning. With more than four entries the list is moved by dragging or with the mouse wheel.
2. Reset counter: resets the counters and the state of alarm and warning – the display turns green again – and closes the dialog. The list is kept.
3. Wastebasket: after a confirmation deletes the list and also resets counters and state.

Setup

This section is meant for the installer of the system.

The evaluation runs in the function block Block Alarm memory basic; the control element only displays it. First create the function block and its addresses, then right click on the control element and select the function block. In the same menu Take comment takes over the name of the function block as text.

• When an alarm is counted – on a rising or falling edge, on every change or on a telegram – is set by the parameter Trigger alarm at the function block, the maximum number of list entries by the parameter Number of buffers.
• Counters, state and list are kept in the controller and survive a restart.

Parameters

Address links

All addresses – alarm and warning, each with trigger, reset, status and count – sit at the function block and are taken over when linking.
