Components — Message Interface (MI-100)
Statement
Various meaningful values are possible, depending on the
source of the statement (subject to SIMON LINK updates):
–
*
: Failure
–
ZI
:
~ Failure
~ Mains failure
~ WTS close on wind / rain
~ Signal 1 / 2 / 3 / 4 / 5 (digital input)
–
SI
/
SI*
:
~ Failure
~ ALARM triggered
~ ALARM on line 1 / 2 / 3
~ Reset signal
–
MR
/
MR*
:
~ Failure
~ Alarm triggered
~ Command Open
~ Command Close
–
MI
:
~ Failure
~ Relay on 1 / 2 / 3 / 4
Logical operation
The relays only differentiate between ON and OFF and in the
same way the logic operations only differentiate between
YES and NO. This means:
NOT ( NOT ( statement)) = statement.
Logical operators are defined as follows:
–
NOT
:
–
AND
:
–
OR
:
Examples
– The statement “ALARM from indicating line 1” on the
SI-100 is to be evaluated:
SI*: Alarm_on_Line_1
– The system is in OK operating state:
NOT( *:Failure)
– The statement “ALARM from indicating line 2” of the first
SI-100 and not on the second SI-100 is to be evaluated:
SI1: Alarm_on_Line_2
AND
NOT SI2: Alarm_on_Line_2
– The statement “ALARM from indicating line 1” of the first
SI-100 and not from the other two indicating lines:
SI1: Alarm_on_Line_1
AND
NOT (SI1: Alarm_on_Line_2 OR
SI1: Alarm_on_Line_3)
2.7.2.b Switching delay
After reaching the condition (logical statement is
true), the dry contact (relay) is switched either as
long as the condition remains true or for a preset
time (1 second to 1 hour)
2.7.2.c Hold time
After reaching the condition (logical statement is
true), the dry contact (relay) is switched either as
long as the condition remains true or for a preset
time (1 second to 1 hour).
Even if the condition changes during the hold time, the relay
remains switched until the hold time has elapsed. Only after
the holding time has elapsed the relay is released and reacts
again to status changes of the condition.
