Data Type
CharacterString
Objects
Binary input, Binary output
Description
Binary Input:
This property, of type CharacterString, characterizes the in-
tended effect of the INACTIVE state of the Present_Value
property from the human operator's viewpoint.
The content of this string is determined locally, but it is in-
tended to contain a description of the ACTIVE state that can
be read by the user. For example, if the physical input is
connected to a switch contact, then the Inactive_Text prop-
erty might be assigned a value such as "Fan 1 Off". If either
the Inactive_Text property or the Active_Text property are
present, then both of them shall be present.
Binary Output:
This property, of the type CharacterString, characterizes the
intended effect, from the human operator's viewpoint, of the
INACTIVE state of the Present_Value property on the final
device that is ultimately controlled by the output. The con-
tent of this character string is locally determined, but it is in-
tended to contain description of the INACTIVE state that
can be read by the user. For example, if the physical output
is a relay contact that turns on a light, then the Inactive_Text
property might be assigned a value such as "Light Off". If
one of the optional properties Inactive_Text or Active_Text
is present, then both of these properties must be present.
