Format Summary

Devices are named with a sequence of characters in the following format:

Wiki Markup
{center}{*}DeviceType* : *Area* : *Position{*}{center}
An example of a device name looks like this:
Wiki Markup
{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:
Wiki Markup
{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:
Wiki Markup
{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.
