3. FUNCTIONTRIGGER
Triggers (up to 8 triggers)
A trigger can be an independent object,
A trigger can be any object type, (eg 1 bit, 1 byte, to 4 bytes)
Any change of state will trigger (start the logic / run the logic)
5. OPERATION
Logic Operation
What you want to occur / calculate / run
• 1-4 operations possible
• Multiple types of calculations
• Operand 1 (
fi
rst link / value)
• Operation (gate, NOT,AND, OR, XOR, NAND, NOR, NXOR
• Result (result of above calculation) (you can use this result
internally for next calculations)
6. RESULT
Result Operation
What you want to send after calculation
• 1bit to 4 byte
• Value you want to send (this must be a calculation result from
operation)
• Condition (if you want to
fi
lter the result, eg send 0 only)
• Sending mode (always, if result is different, periodic)
• Delay, (any delay before sending).
7. LOGIC EXAMPLE
HVAC / HYDRONIC Zone Control
4 Zone. 1 head unit or boiler
Trigger : 1 bit data entry 1, 2, 3, 4.
Condition : Nil
Operation 1 : 1 bit data entry 1, or 1 bit data entry 2, = b1
Operation 2 : b1 or 1 bit data entry 3, = b2
Operation 3 : B2 or 1 bit data entry 4, = b3
Result : B3 no restriction, always.
8. LOGIC EXAMPLE
HVAC / HYDRONIC Zone Control
4 Zone. 1 head unit or boiler
Con
fi
guration : 4 x 1 bit data entries
Linking : 1 bit data entry 1, 2, 3, 4 link to zone on / off
Function result : Link to on / off of main unit / boiler
