Setting up connections for a piloted control list
selector
To connect with a network device such as a programmable controller, piloted
control list selectors use tags or expressions. You set up these tags or
expressions in the Connections tab of the Properties dialog box.
Piloted control list selectors have seven tags for sending and receiving data:
The Value tag receives the value of the currently selected state. You
can use this value to trigger an action, for example, to set a motor’s
speed to low, medium, or high.
The Indicator tag selects an item in the list if the piloted control list
selector is being controlled remotely, for example, by a network
device.
The Remote Access tag or expression determines whether the piloted
control list selector can be operated by the operator or remotely, for
example, by a network device.
If the remote access tag has a value of zero, or is not assigned, the
operator can select states in the list. If the remote access tag has a
non-zero value, the selected state is determined by the value of the
Indicator tag or expression.
The Top Position tag receives the value of the state that is the first
item in the list whenever the list scrolls.
The Visible States tag receives the values of all the states visible in the
list whenever the list scrolls. The tag must support arrays, and the
arrays must have as many elements as the number of items visible in
the piloted control list selector.
For example, if the piloted control list selector has 5 visible states, and
the state values are written to network device addresses N7:0 through
N7:4 using RSLinx Enterprise, the Visible States tag should be an
array tag with the following address:
::[RSLinx Device Shortcut ]N7:0,L5
where L5 indicates that the tag writes values to five addresses in the
array.
The Enter tag lets a network device confirm a selection after the Value
tag is written. The Enter tag is set for as long as is specified in the
Timing tab.
The Enter handshake tag or expression resets the Enter tag, using the
Handshake reset type option specified in the Timing tab.
The FactoryTalk Alarm and Event objects provide run-time displays of
FactoryTalk device-based and tag-based alarm data, sources, and activity.
