9-53
Continued from the previous page.
Funtion:
 Event function
Diagrams of the event action type are shown in the following.
1: Deviation high (using SV monitor value), 14: Deviation high (using Local SV value)
(Event set value is greater than 0.) (Event set value is less than 0.)
2: Deviation low (using SV monitor value), 15: Deviation low (using Local SV value)
(Event set value is greater than 0.) (Event set value is less than 0.)
3: Deviation high/low (using SV monitor value) 4: Band (using SV monitor value)
5: Process high 6: Process low
7: SV high: 8: SV low:
10: MV high 11: MV low
( : Set value (SV) : Event set value
☆
: Event differential gap)
16: Deviation high/low (using Local SV value) 17: Band (using Local SV value)
ON: Event action turned on, OFF: Event action turned off
Deviation
action:
When the deviation (PV – SV) reaches the event set value, event ON occurs.
Input value action:
When the measured value (PV) reaches the event set value, event ON occurs.
Set value action:
When the set value (SV) reaches the event set value, event ON occurs.
Manipulated output value action:
When the manipulated output value (MV) reaches the event set value, event ON occurs.
Deviation action between channels:
When the deviation between different channels (PV – PV of comparison channel) reaches the event set value,
event ON occurs.
18: Deviation between channels high (Same action as "Deviation high")
19: Deviation between channels low (Same action as "Deviation low")
20: Deviation between channels high/low (Same action as "Deviation high/low")
21: Deviation between channels band (Same action as "Band")
