Defining a Naming Convention for devices in the LCLS Control System has been an iterative process. The first version was a variation on the existing SLAC SLC Naming Scheme. With the LCLS and the addition of X-Ray transport lines and experimental halls, we decided to extend the Original LCLS scheme to what is described here.

h1. Format Summary

Devices are named with a sequence of characters in the following format:
{center}{*}DeviceType* : *Area* : *Position{*}{center}
An example of a device name looks like this:
{center}{*}QUAD* : *IN20* : *122* {center}
There are functions and parameters associated with devices, which also need to be identified. An _Attribute_ field provides that information:
{center}{*}DeviceType* : *Area* : *Position* : *Attribute* {center}
The _DeviceType_ and _Position_ fields also have optional characters. We can denote optional symbols with *\[* and *\]*, so the names can be described as:
{center}*\[* DeviceType *\]* *DeviceDetail* : *Area *: *\[* PositionPrefix *\]* *Position* : *Attribute* {center}
*To summarize*:
* A Device is named by 3 fields, separated by 2 colons.
* A function or parameter of a device, known internally to the Control System as a Process Variable (PV) is named by the 3-field device name followed by another colon, and the Attribute field.
