LCLS Network Node Naming Conventions

LCLS NamingConventions
LCLS Network
SCCS Computer Account Forms
How-to Setup DHCP for an IOC

Network node names are meant to be consistent with the overall device LCLS Naming Conventions. One exception is that the fields of the PV name are separated by a "-" whereas the fields of a node name is separated by a ":". In addition, node names are in lower case, whereas PV names are all uppercase, due to SLC Controls System restrictions on VMS. A limitation of 24-characters is also current inforced due to a restriction on the VMS EPICS Channel Access Server.

The network node name conforms to the following format: <Device Type ><Area ><Position>

The DeviceType Field for network devices is 2-4 characters in length and can be found in the Table 1.0. The Area Field is 4-character field, with numbers and letters and can be found in Table 1.2. The Position Field contains a 2-character, a Subsystem Prefix, followed by a 2-digit Index from 01 to 99. The Prefix designates a subsystem of the control system as follows in Table 1.2.

Examples of a device name would look as follows:

The Area Field


The Area field is 4 characters in length. There are currently 24 areas in the LCLS Accelerator. Going from the Drive Laser to the Experimental areas they include:\
