Discrete Input Object, Class 0x08 (C440)
Discrete Input Point Instance Services (C440)
Discrete Input Point Object Instance #1–4 (C440)
Input Point Value
The input point value reflects current state of the associated
input terminal.
Discrete Output Object, Class 0x09 (C440)
The Discrete Output Point (DOP) Object models discrete
outputs in a product. Note that the term “output” is defined
from the network’s point of view. An output will consume
data from the network. The output is read from this object’s
VALUE attribute and applied to the output terminal.
Discrete Output Point Instance Services (C440)
Discrete Input Point Object Instance #1–4 (C440)
Output Point Value
The output is read from this object’s VALUE attribute and
applied to the output terminal.
Communication Fault Action
Determines the action to be taken at the output terminal
when a communications fault occurs.
If this attribute is set to “0,” then output terminal will be set
to the state determined by attribute “Communications fault
value.”
If the attribute is set to “1,” then the output terminal is not
changed due to a communications fault.
Default: “0”
Communication Fault Value
Determines the value to be applied to the output terminal if a
communications fault occurs
AND the “Communication fault action” attribute is set
to “0.”
Default: 0.
Idle Action
Determines the action to be taken at the output terminal when
communication idle occurs. If this attribute is set to “0,” then
output terminal will be set to the state determined by attribute
“Idle value.”
If the attribute is set to “1,” then the output terminal is not
changed due to a communications idle event.
Default: “0”
Idle Value
Determines the value to be applied to the output terminal if
a communications idle event occurs AND the “Idle action”
attribute is set to “0”.
Default: 0.
