Names are broken down into the standard parts, DeviceType : Area : Position : Instance (Where needed) : Attribute.
RTD sensors placed on a device, will take the device name specified in the MAD deck.
Device Type
ACCL | Used for everything in the RF system that is part of the general physics and operations interface at the cavity level. Also used for penetration |
GUN | Used for everything in the gun |
COLL | Used for Collimators |
WIRE | Used for Fast wire scanners |
TORO | Used for ICT |
FARC | Used for Faraday Cup |
ROOM | Used for Air sensors in tunnel/building |
LLRF | Used for phase reference line |
WATR | Water system |
Area, Subset of Accelerator With RF Devices

All AREA field are taken from the document.
Position
See https://slacspace.slac.stanford.edu/sites/lcls/lcls-2/wd/dsg/Forms/AllItems.aspx, Naming Convention section 6.1.2.3.2

Attribute
Attributes that comprise the physics interface. Scalar unless otherwise specified
| R/W | Name | Description |
---|
| R | TEMP | Measured temperature from PLC(degC) |
| R | FLOW | Measured flow from PLC(GPM) |
| R | PRLTEMP | Measured temperature from PLC for Phase reference Line(degC) |
| R | PENTEMP | Measured temperature from PLC for cable penetration(degC) |
| W | HLIMDES | High limit for interlock Sensor |
| W | LLIMDES | Low limit for interlock Sensor |
| W | BYP | Bypass request for interlock sensor |
| R | BYPSTAT | Bypass readback for interlock sensor |
| W | RESET | Rest interlock Fault |
| R | ALARM | Interlock Alarm Status |
Attributes highlighted in Bold will be only present for sensors interlocked for MPS. These attributes in bold will be appended to the temperature or flow signal. eg:
SOLN:GUNB:212:FLOWHLIMDES
SOLN:GUNB:212:TEMPHLIMDES
Some Non Mad sensors:
Room air , water and phase reference line sensor:
RTD Z location is co-related with https://slacspace.slac.stanford.edu/sites/lcls/lcls-2/as/controls/CD2/General/Naming/LCLS-II_Device_Names.xlsx (see AreaStartandEnd Tab for detail) to find the area name. The position field uses numbers ranging from 1 to 99 depending upon the instance of the sensor in the area. See See https://slacspace.slac.stanford.edu/sites/lcls/lcls-2/wd/dsg/Forms/AllItems.aspx, Naming Convention section 6.1.1 for detail.
Penetration sensor.
penetration Z location is co-related with https://slacspace.slac.stanford.edu/sites/lcls/lcls-2/as/controls/CD2/General/Naming/LCLS-II_Device_Names.xlsx (see AreaStartandEnd Tab for detail) to find the area name. The position field uses numbers ranging from 1 to 99 depending upon the instance of the penetration in the area. (please note all though penetrations are names with sector names, we will only use that as a description, but use area names as defined in the document above for the PV.)
Instance field will be used for penetration sensors as each penetration will have qty 3-6 sensors installed.
Penetration Z location information can be found here:
