You can create rules which can check between all logical (Yes/No) and numerical (digits) fields in Roon Data and the Item Data. The type is automatically determined when you choose the fields between which you want to set up the rule. Table 1 illustrates the correlation between field type and the type of rules which can be created.
RDS Room Data field: | Item Data field: | Can be counted down: | Result: |
Logical | Logical | No | Under-specified
If the Item field is "Yes", the RDS field must also be "Yes".
Example: If the Item is flagged for vacuum, the RDS field "vacuum" must also be flagged.
Over-specified:
If there are no Item in the room with the "Yes" field, neither shall the RDS field have "Yes".
Example: If no Item in the room require vacuum, the RDS field "vacuum" shall not be flagged. |
Numerical | Logical | Yes | Under-specified
The RDS field must be equal to or greater than the number of Item in the room where the Item field is flagged.
Example: If the Item is flagged for power supply, the number of sockets in the room must be greater than or equal to the total of all these Item which require power supply.
Over-specified:
The RDS field must not be greater than the number of Item in the room where the Item field is flagged.
Example: The number of power sockets in the room must not be greater than the number of Item which require power. |
Logical | Numerical | No | Under-specified
If an Item in the room has a field greater than 0, the RDS field must be flagged.
Over-specified:
If no Item in the room has a field greater than 0, the RDS field must not be flagged. |
Numerical | Numerical | No | Under-specified
You can choose an operator with which to compare values. If you choose '>', the value of the Item field must be greater than or equal to the value in the RDS field. If you choose the '<' operator, the Item field must be less than or equal to the RDS field.
Example: The minimum temperature for the Item must be greater than or equal to the minimum temperature in the room.
Over-specified:
Reverse the operator selected (for under-specified).
For example: The minimum temperature for the Item must not be less than the minimum temperature in the room.
Check whether over-specified for this type of rule actually has any practical significance. |
Numerical | Numerical | Yes | Under-specified
The sum of the Item field for all Items in the room must be less than or equal to the value in the RDS field.
Example: The number of data connections for all Item in the room must be less than or equal to the number of data outlets in the room.
Over-specified:
The value in the RDS field must not be greater than the total of the Item field for all Items in the room.
For example: The number of data connections for all Items in the room must not be greater than the number of data outlets in the room. |
