The Or connection
Okay, from now on the emergency conditions are set:
1. Glass breach and water level drops below 80%
2. Glass breach and water found at visitors observation room
Es However, it may now be the case that the water level drops and / or water is reported in the visitors' area without an obvious glass
breakage. This may happen and someone need to mainenance this issue, but it is not really critical. In some cases it could be wanted.
To show this scenario, a third marker can combine both conditions with an OR:
This basic marker can be used as a non-critical overview lookup:
1. Water level below 80%
2. Unusual Humiditiy or liquids found at visitors observation room
With the OR operation, these two conditions can occur independently of each other - in both cases, the marker is set to high – on the
other hand, this marker will only fall back to off position if all standard maintenance work is done.
Switching outputs
In this example scenario, many trigger points are included. For the matrix, these issues are configured:
- Glass breach and dropping water level
- Glass breach and water/liquids at visitors observation room
- Dropping water level or water/liquids at visitors observation room
Die kritischen Probleme sind hierbei mit festen UND-Bedingungen verknüpft, da ein schnelles Handeln erforderlich ist. Die
Eskalationsstufe ist, dass alle 3 Ereignisse aufeinandertreffen: Es gibt ein Glasbruchproblem, der Beobachtungsraum läuft voll Wasser
und der Füllstand auf 80% gesunken ist.
The critical issues here are linked to fixed AND conditions because quick action is required. All three problems together means, visitors
can be endangered: There is a glass break problem, the observation room will be filled by water and the water level has dropped below
80%. Perfect for automatic emergency procedures - all critical l markers can be summarized and linked to an output:
As long as marker 1 and marker to are set to ON (high), output 1 will be triggered: :
This output can inform ordinate and subordinate monitoring systems via alarm contacts, switch of switch off sockets near the floor, etc.
Via the event "Output 1 On", any additional job chains can be created inside for advanced automatic emergency measures.
Fallbackt o normal state
The output will be switched off in case of one of these markers fall back to normal state.
Note
As with the configuration of the markers, you can create an And / Or dependencity between up to 8 different markers. As an examle, this
function is useful if a machine may only be startet if preconditions like pressure, temperature, etc. met specific operating values. By
using the matrix, the output that unlocks the start button will not be released until all conditions have been met..
