Proposal: name each ion pump with respect to its camera (Green/Red) and the side of the spectrometer it is on (Echelle/Collimator). The driver here is that the name then gives the location of the pump (whereas labels like “Green #1” or “Red 10 o’clock” or “Green Prime” require more information to derive the position).
However: Brad - please let me know if this is too cumbersome!

Required Alarms
Parameter | Threshold | Notes | |||||||
|---|---|---|---|---|---|---|---|---|---|
| 1 | GRN_ION_E pressure too high |
| Only one pump per cyrostat will be in operation at any time. The alarm system would need to know which pump/controller is in operation at any time to monitor the correct pressure value. | ||||||
| 2 | GRN_ION_C pressure too high |
| |||||||
| 3 | RED_ION_E pressure too high |
| |||||||
| 4 | RED_ION_C pressure too high |

Device Command List for KPF
Noted as a ‘draft’ at this point as I need to finalize Arc Detection command setting.

|---|---|---|

...
Keyword | Value | Type |
|---|---|---|
$(NAME)_CURR | The current at the pump in Amps. | Double - read only |
$(NAME)_VOLT | The voltage at the pump in … Volts. | Double - read only |
$(NAME)_STATUS | Current controller status - see manual for details | String - read only |
$(NAME)_PUMPON | Is the pump on? 0 - no 1 - yes 2 - unknown (most likely only at startup or if connection lost) If written, will apply that state. Unknown is a no-op on a write. | Enumerated - is writable. |
$(NAME)_LCK | Locks turning the pump off and on. 0 - Locked 1 - Unlocked | Enumerated |
$(NAME)_IP_MODEL | Model of the device as reported by the device. | String - read only |
$(NAME)_IP_FIRMWARE | Firmware version of the device as reported by the device. | String - read only |
DISP#XXXX | Usual dispatcher keywords. STOP - stops dispatcher CONN - IP address and port DEV - device name from config file STA - status and includes whether or not a connection is made. |
...
Configuration File
The required sections are:
main which points to service name and stdiosvc configuration file
device which has the details of the device
dispatcher which has the dispnum value and the $(NAME) variable
Configuration | Value | Explanation |
|---|---|---|
address | 192.168.23.149 auxrack-ionpump-3 | the IP address of the device, can include an optional name from /etc/hosts |
port | 23 | IP port to telnet to |
poll_time | 5 | how often to query for the data from the device |
device_name | Green Collimator IP | this is the value of the DISP#DEV keyword, so a long name is helpful |
cal | 1.00 | the calibration value, applied at the initial connection by the dispatcher, needs to be between 0 and 1 |
size | 2.0 | the size of the pump in L/s, should be 2.0 |
dispnum | 2 | the number of the dispatcher |
name | Coll | The short name used for keywords as $(NAME). The service name will include the name of the cryostate (kpfgreen / kpfred) and this is for the IP. |
