Programming with SIMPL Windows

SIMPL (Symbol Intensive Master Programming Language) is an easy-to-use
programming language that is completely integrated and compatible with all
Crestron system hardware. The objects that are used in SIMPL are called symbols.
SIMPL Windows offers drag and drop functionality in a familiar Windows
environment.
SIMPL Windows is Crestron Electronics’ software for programming Crestron
control systems. It provides a well-designed graphical environment with a number
of workspaces (i.e., windows) in which a programmer can select, configure,
program, test, and monitor a Crestron control system.
The next two subsections describe a sample SIMPL Windows program that utilizes
the CNXRY-8. The first subsection details how the sample program works with a
textual description and block diagram. The second subsection provides a broad
description of how to actually create the SIMPL Windows program.
NOTE: The following description assumes that the reader has knowledge of
SIMPL Windows. If not, please refer to the extensive help information provided
with the software.

How the Program Works

A basic CNXRY-8 SIMPL program is shown on the next page in block diagram
form. For this example, the CNXRY-8 occupies slot 1 of a CNMSX-PRO. Assume
there are two rooms that have lighting systems that are controlled via relays. Each
room can have up to four 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 A4; room 2 uses relays A5 through A8. When the
user presses any of the buttons for room 1 (join numbers 1-4), 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
