Sample logic program that shows a way to configure a Powermonitor 3000 User Configurable Data Table
from a ControlLogix controller via the 1404-NENET communications option card using Ethernet/IP.
See the accompanying text for a list of tags to be created in the ControlLogix controller.
The first rung allows a selection of tables to write to the PM3000. Enter a 0, 1, or 2 into the tag "Select"
to select between the default table, a custom table, or an "Undo" of the last write. The selected
table is copied into the "Download" table. The rung logic also copies the PM3000 password into the "Download" table .
If the password is changed from the default (0), the new password must be entered into the tag "pwd."
Toggle the "Start" tag to begin.
