The Binary Control function, which performs a control operation on a binary output point,
based on the state change of a binary input point. A millisecond time filter can be applied to
value changes in the source point, to prevent control operations from being triggered on
transitions of short duration.
The Binary Debouncing function is the answer to a typical binary signals problem, by
filtering short-term transitions, considered as non-significant.
The Create function, allows you to create a logical analog or binary input point that acts as a
data holder. The only way to modify the data point is by using a Force operation, using the
Force function. A validity delay can be specified to define a refresh period after which the
value of the created point must be refreshed to maintain a valid status. If the value is no longer
refreshed using the Force function after this delay, the point inherits the bad quality status.
This function, in conjunction with the Force function, allows a slave to update a input point
value (binary or analog) that can be read by any other slave.
The Force function, which forces the value or state of an analog or binary input point, based
on control operations performed on force and unforce output points created by the function.
The Grouped Control function, which performs a control operation on a group of output
points, based on the value or state change of an analog or binary control point.
The Inhibition function, which uses a logical output point to control a group of physical
output points for the purpose of enabling or disabling control functions. This function can also
be used with physical input points, in which case it enables or disables reporting of transitions
for those points.
The Input Latching and Reset function, which changes the state of a logical input point,
called a latched point, whenever it detects a transition or pulse on a physical binary input
point. The latched point remains “on” until either a reset operation is done on a binary output
reset point or an internal timer expires. Optionally, the control operation on the reset point can
also apply to a physical binary output point called the controlled point.
The Logical function, which dynamically computes an “AND” or “OR” operation on a group
of binary input points. The result of this computation is stored in a logical binary input point.
The Logic Processor defines logical data points which values are based on calculations
performed on physical points that you build in the Logic Editor, to process existing points
through different operations described further. It is a much more elaborated version of the
Logical function.
17.1.1 Adding an Automation Functions Instance
Proceed as follows to add an Automation Functions instance using SMP Config:
In the left pane, click Automation Functions, under Master Protocols.
In the right pane, assign a name to the new instance.
The new instance appears in the left pane.
