All fields are required to be Upper Case characters the the exception of the Attribute field which is allowed to be mixed case with the following constraints.
- There must be zero requirements for access to the PV from the SLC Control System (SCP). The SLC Control System is case insensitive and will be unable to read the mixed case PVs.
- Is it strongly suggested that UpperCamelCase* be used for mixed case, however all uppercase still should be used as much as possible when creating new PV names. We realize that when we bring in support from other labs, the case may have a different format, but all PVs names that we create should either be all upper case or UpperCamelCase .
- The attribute part of the name is the only part that is allowed to have mixed case, device, area, and unit number fields are still required to be all upper case.
- It is not allowed to have different PVs which only differ in case.
The entire name is currently restricted to 28 characters or less.
The DeviceType is between 3 and 9 characters in length. The generic type of device is denoted by 3 or 4 characters, and may optionally be followed by an underscore with 3 or 4 more characters to indicate details of that device.
The Area field is 4 characters in length, and describes one of the 21 areas currently in the LCLS Accelerator.
The Position field can be up to 4 characters in length, which includes either an optional 1-character position prefix followed by 3 digits (for devices associated with the beam line) or 2-character prefix followed by an index for non-beam-line devices which are itemized.
The Attribute field must be 12 characters or less.
All PV names must be unique in the control system. This includes being unique across machines such as LCLS, SLC, FACET, FACET-II, and LCLS-II.

The optional fields are meant to accommodate the SLC-Aware IOC mechanism, which has even more restrictions placed on Device names. For more information, from the original Naming Convention plans, click here.
