CRESTRON
SIMPL
SIMPL is CRESTRON’s programming language designed for easy implementation
of the control system requirements. The best representation of SIMPL programming
is the block diagram. A basic ST-LT SIMPL program is shown and described below.

The sample ST-LT SIMPL program allows two scenes for the Grafik Eye; scene 2
on Main Unit 1 and scene 16 on Main Units 7 and 8. It also allows zone 3 to be
ramped up and down. The MV symbols are used to detect the release of the UP and
DOWN buttons which results in the transmission of the appropriate zone up/down
stop commands.
Workshop
The CRESNET II Workshop is designed to simplify the various operations needed
to program and run a CRESNET II control system. The series of screen displays
shown below are accessible from the “Define Network” option of the SIMPL-I
Menu in the CRESNET II Workshop. These screens are shown to clarify the means
of assigning signal names for the SIMPL program in the previous illustration.

The ST-LT definition supports a subset of the ST-COM definition; use A_IN,
A_OUT for serial string transmission as well as the regular “in” and “out” directions
for hard-coding serial data.
