System Info - DLS-Controls-Private-org/MBF-docs GitHub Wiki
This shows static configuration and version information about the system. The following PVs (all prefixed with device name $(device)) are shown here:
| Title | PV | Description |
|---|---|---|
| Version, Git Version | :INFO:VERSION, :INFO:GIT_VERSION | The EPICS driver software version is shown in two variants. The plain version PV is manually maintained, and so contains the "official" version number. The git version PV is generated from the git repository and so can contain more detailed information. |
| FPGA Version, FPGA Git | :INFO:FPGA_VERSION, :INFO:FPGA_GIT_VERSION | Similarly, there are two version codes for the FPGA. The first is the manually maintained version, the second records the status of the git repository when the firmware was built. |
| Driver version | :INFO:DRIVER_VERSION | For the kernel driver only the manually maintained "official" version number is shown. |
| Hostname | :INFO:HOSTNAME | This is the machine host name on which the EPICS IOC is running. This is provided for scripted access to the socket interface to the fast memory and detector memory. |
| Data socket | :INFO:SOCKET | This is the socket number for the interface to the fast memory and detector memory readout. |
| Device name | :INFO:DEVICE | For direct access to the fast memory and detector memory this device name can be used to locate the device node. The device nodes are located in the directory/dev/amc525_lmbf/, so the fast memory node can be read from |
/dev/ams525_lmbf/$(caget -t ${device}:INFO:DEVICE)/amc525_lmbf.ddr0
| | System mode | :INFO:MODE | This PV indicates whether the device is operating in transverse "TMBF" or longitudinal "LMBF" mode. | | Bunches |
:INFO:BUNCHES
| This is the number of buckets in the ring (parameter of the machine). | | ADC taps | :INFO:ADC_TAPS | This is the number of taps available for the ADC compensation filter. | | BB taps | :INFO:BUNCH_TAPS | This is the number of taps available for the bunch by bunch feedback filter. | | DAC taps | :INFO:DAC_TAPS | This is the number of taps available for the DAC pre-emphasis filter. | | Axis 0, Axis 1 | :INFO:AXIS0, :INFO:AXIS1 | For scripted access, the names of the two channel axes are provided here. In LMBF mode there is a third PV,:INFO:AXIS01, which is used for the name of the combined axes. |
