Overview

TPD5 uses Function Codes to specify how TPD5 elements interact with and control devices on the control system. In TPD5, the term Function Codes refers to all three of the code types that can be assigned to buttons:

• • Channel Codes: Displayed in the upper-left corner of the button, channel codes indicate the port number and the channel code associated with the button. The channel codes represent communication out of the panel to the master controller.
  • Address Codes: Displayed in the lower-right corner of the button, address codes represent communication from the master controller to the panel, causing the panel to do something (i.e. indicate feedback, display a text string, etc).
  • Level Codes: Displayed in the lower-left corner of the button, level codes represent bi-directional communication between the panel and the master controller (i.e. the panel can cause a change in a level setting, and a changed level setting generates feedback on the panel).

Function Codes are assigned via the Programming tab of the Properties window.

NOTE: The easiest way to handle function codes is to create and f inalize your touch panel pages and buttons (with function codes) before generating the supporting NetLinx code. That way, in case you have to change any aspect of the project (i.e. add/remove controlled equipment, test strings, graphics, etc), you can update the function code assignments in TPD5, rather than having to re- write your code.
