Values
Description
'START mode'
'No automatic activation'
The operating personnel can only activate the control
manually with a command.
'Formula true'
The system activates the control when the Boolean
expression in the 'Formula' field is true.
'Value rising and >=
threshold (all causes OR-
combined)'
The system activates the control as soon as a
certain number of events for the relevant event
category has occurred within an assigned cause
element.
The number of events is configured in the detail
editor of the cause element with the 'Threshold'
parameter. You will find more information about this
parameter further down in a separate section
198] on the parameters of the 'Causes'
assignments.
'STOP mode'

'Formula false'
The system deactivates the control when the
Boolean expression in the 'Formula' field is false
again.
'All causes inactive'
The system deactivates the control when all
assigned causes are inactive again.
'Formula'
Input field
Several causes can be assigned with a formula. The
following operators are possible:
●
OR = '+'
●
AND = '*'
●
NOT = '–'
When brackets are used, a mixture of operators can
also be used.
Example: '1 * (2 + 3)' means '1 AND (2 OR 3)'.
If no formula has been defined, all causes are linked
with the OR function.
'Activation delay'
Input field for time period
[hh:mm:ss]
Adjustment range: 0...30
min
Increments: 1 sec
The parameter determines the length of the
activation delay for the causes function when the
activation conditions are met.
'Deactivation delay'
The parameter determines the length of the
deactivation delay for the causes function when the
deactivation condition is met.
