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 However, the node names are separated by a dash, "-" whereas the fields of a node name is separated by a colon, ":". In addition, node names are in lower case, whereas PV names are all uppercase, due to SLC Controls System restrictions on VMS. In LCLS-II the uppercase restriction has been lifted for the attribute field of the PV name. A limitation of 24-characters is also current inforced due to a restriction on the VMS EPICS Channel Access Server. This too is  a restriction lifted for LCLS-II.

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

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 1.1. Network devices, with the exception of IOCs tend to use the access building location rather than the sector, as some access buildings may server multiple sectors, such as B005.  The Position Field contains a 2-character Subsystem Prefix, followed by a 2-digit Index from 01 to 99. The Subsystem Prefix designates a subsystem of the control system as follows in Table 1.2. The Subnet Field is currently only used for a secondary NIC on the processors.  Currently this is only used for fast feedback subnet, in which "-fnet" is used.
