epicsdev_ps_caen_easydriver

EPICS PVAccess server for CAEN EASY-DRIVER power supplies.

This server implements remote control over TCP/IP using the EASY-DRIVER command set from:

• misc/EASY-DRIVER - User's Manual V2.pdf

and exposes the same operational PV names as in:

• misc/devEasyDriver.db

Implemented PVs

The server hosts these PVs (same names as the DB records):

• Version
• Enable
• Reset
• SlewControl
• Setpoint
• BulkVoltage
• RegulatorTemp
• ShuntTemp
• OutputVoltage
• SupplyOn
• GenericFault
• FETovertemp
• ShuntOvertemp
• DCunderV
• ExternalInterlock1
• CurrentRBV
• SlewControlRBV
• ControllerKp
• ControllerKi
• ControllerKd

Command mapping summary

Runtime polling and status use:

• MST → status bits
• MRI → current readback
• MRV → output voltage
• MRP → bulk/DC-link voltage
• MRT → MOSFET temperature
• MRTS → shunt temperature
• MVER → version/model string

Control operations use:

• MON / MOFF → enable/disable output
• MRESET → reset status/fault state
• MWI / MRM → setpoint write (immediate/ramped)
• MWG + MPUP → controller gains (Kp, Ki, Kd)
• MRG → read stored gain values

Running

Example:

python -m epicsdev_ps_caen_easydriver --host 192.168.0.10 --port 10001

Useful options:

• -d, --device device prefix base (default: caen_edrv)
• -i, --index device index (default: 0)
• --host EASY-DRIVER IP/host
• --port EASY-DRIVER TCP port
• --timeout socket timeout
• --range override setpoint range in A

The published PV prefix is:

• <device><index>:

With defaults, PVs are published as:

• caen_edrv0:<PVName>
