SIMPL Windows Programming

Introduction to SIMPL

Primer – DOC. 6253
Crestron engineers are dedicated to the development of our products and the
interface with other manufacturer's equipment. However, control systems need
individual programming in order to be customized for each installation. Crestron
control systems are programmed using SIMPL (Symbol Intensive Master
Programming Language).
SIMPL is an object oriented programming language designed for easy
implementation of your control system requirements. The objects that are used in
SIMPL are called symbols. Each symbol has a specific set of operations that it will
perform. The lines that connect symbols are called signals. The collection of SIMPL
symbols and their interconnection to one another is the program. Therefore, the
program is actually a picture created with objects (symbols) and lines (signals). This
type of picture is also referred to as a block diagram or flow diagram in other
applications. When planning an A/V installation, a block diagram indicating how all
of the system equipment is connected is essential to the installer. SIMPL allows the
programmer to develop a control program in a similar fashion. The collection of all
the symbols being used and the signals that connect them create a picture similar to a
block diagram. The development of a SIMPL program is intimately tied to the block
diagram of the A/V installation.

Symbol Categories

Writing a program in SIMPL is similar to wiring a circuit: you have to choose the
right components, and you have to wire them together properly. As just described, in
SIMPL the components are called symbols and the wires are called signals. Just like
in real-world electronics there are a multitude of symbols to choose from to
accomplish your goal, as you program more and more systems you will likely find a
subset of symbols that you use for most situations.
Symbols in SIMPL can be divided into two broad categories: device symbols and
logic symbols.

Device Symbols

Device symbols represent Crestron network control devices that can be included in a
program. They can be placed into or deleted from the program in the Configuration
Manager section of SIMPL Windows only. The Program Manager allows device
