DO points#

DO point can be used to control physical relay in DO module, control a physical contact in DOOC module, display a logical value controlled by IEC program and display logical value controlled manually.

Point info#

  • Pointname: Unique name for the point inside the FX-controller. Any other point cannot have the same name.

  • Description: Used to describe the point.

Point levels#

Point levels are part of user rights management. Value is minimum user level to be view, set or program the point. If user level is under the value, they are not able to see, set or edit the point.

Local connection info#

  • Module: Physical modules modbus address.

  • Port: Physical modules port.

  • Point: Point number of the physical connection in module.

Global point#

With global point it is possible to read a points value from other FX-controller.

  • Controller: The name of FX-Controller the data is read from.

  • Pointname: The point name of point in the other FX-Controller the date is read from.

Point details#

  • Statetext: Select state text -group for displaying point state in text mode, instead of number value.

  • Start delay [sec]: Time it takes for point to go on after request. NOTE! Manual-lockstate overrides the delay.

  • Stop delay [sec]: Time it takes for point to go off after request. NOTE! Manual-lockstate overrides the delay.

  • Time schedule: Select time schedule point that gives the state of DO point, when the DO point is in lockstate auto.

  • Tristate: While selected for physical point it reserves two physical points from DI module.

    Note

    NOTE! Both points must be on same physical module!

Possible values of tristate#

Value

State

0

Both contacts are OFF

1

First contact is ON, second contact is OFF

2

Second contact is ON, first contact is OFF or ON

  • Default value in DO module: Select value for point if CPU’s communication is stopped for over 30 seconds. Selection Old value will keep the latest value. Selection On will default to On and selection Off will default to Off.

  • Special point type: State Normal = no lock point. State Limited = DO point may not have higher value than lock point. State Over ride = DO point follows value of lock point. Selection Lockstate defined sates of DO point where lock point is effective. This functionality makes it possible to control DO point without IEC program.

  • Picture: Select a process picture that will be opened when clicking graphics symbol on point settings of this point.
