After the DirectLogic driver class is selected the following dialog appears.

The selections are as follows:

Tag: User defined object name that can be referenced for connecting

other objects.

Comm Link: The associated link chosen for the configured driver

object. When the “…” button is pressed the Select Link dialog will

appear.

Poll Rate= is a numerical expression that determines how often to poll

the device in milliseconds.

Poll is a logical expression. When the expression changes from false

to true, LookoutDirect polls the device one time. You can use a simple

expression like the signal from a pushbutton, or a complex algorithm.

If a link is not available, you will have to add one. Click the Add… button

to create a new communications link then select the correct Serial or

Ethernet port that you have the cable attached from your PC to the PLC.
