How the Program Works
A basic TPS-TPI touchpanel interface SIMPL program is shown after this paragraph
in block diagram form. For this example, the display connected to the TPS-TPI is the
user interface (or touchpanel) in a control system containing a CNMSX-PRO, which
has a CNXRY-16 occupying slot 1. Assume that the TPS-TPI is used to control a
lighting system via relays in two rooms. Each room can have up to eight scenes of
lighting. A scene is engaged by latching a relay. Only one scene can be activated in a
room at a time.

Room 1 uses relays A1 through A8; room 2 uses relays B1 through B8. When the
user presses any of the buttons on the TPS-TPI for room 1 (join numbers 1 through
8), the corresponding signal goes high on the input of the Interlock symbol for room
1. The corresponding output of the Interlock latches high. Since the Interlock is
mutually exclusive, only that output is high. The corresponding relay then latches
high on the CNXRY-16 card.
