OWA-EPANET Toolkit  2.2
[CONTROLS]

Purpose:

Defines simple controls that modify links based on a single condition.

Format:

One line for each control which can be of the form:

   LINK linkID  status  IF NODE   nodeID  ABOVE / BELOW   value

   LINK linkID   status   AT TIME  time

   LINK linkID   status   AT CLOCKTIME clocktime   AM / PM

where:

linkID=  a link ID label
status=   OPEN / CLOSED, a pump speed setting, or a control valve setting
nodeID=  a node ID label
value=  a pressure for a junction or a water level for a tank
time=  a time since the start of the simulation in hours
clocktime=  a 24-hour clock time (hrs:min)

Remarks:

  1. Simple controls are used to change link status or settings based on tank water level, junction pressure, time into the simulation or time of day.
  2. See the notes for the [STATUS] section for conventions used in specifying link status and setting, particularly for control valves.

Examples:

[CONTROLS]
;Close Link 12 if the level in Tank 23 exceeds 20 ft.
LINK 12 CLOSED IF NODE 23 ABOVE 20

;Open Link 12 if the pressure at Node 130 is under 30 psi
LINK 12 OPEN IF NODE 130 BELOW 30

;Pump PUMP02's speed is set to 1.5 at 16 hours into the simulation
LINK PUMP02 1.5 AT TIME 16

;Link 12 is closed at 10 am and opened at 8 pm throughout the simulation
LINK 12 CLOSED AT CLOCKTIME 10 AM
LINK 12 OPEN AT CLOCKTIME 8 PM
