Redis IOC

A StreamDevice based EPICS IOC that interfaces with Redis databases.

Utilization

Change the IOC table sync URL in the Makefile or swap out the table in scripts/spreadsheet.

Each row represents a different PV, and you can configure it through columns.

Then, run generate.py. A cmd folder will be generated.

Necessary Parameters:

• Enabled: True enables the PV, False disables it.
• IP: Redis server IP (must use port 6379). This IOC also supports redundancy, which must be enabled by setting multiple IPs, separated by commas (,).
• Key: Redis key
• PV: PV name
• Precision: Digits of decimal precision (only applies to float-related fields)
• Unit: EGU
• Scanrate: Scanrate. Follows default StreamDevice values.
• Type: Data type (float, float_put, int, int_put, string, string_put, array, array_put, hash, hash_put)
  • Variables with the put suffix allow for caput commands
  • Since Redis returns a string for most, this only affects how Redis' response is processed

Optional Parameters:

• Rack: Doesn't affect the IOC
• ADDR: Doesn't affect the IOC
• Location: Passed over to DESC field
• HIHI/HIGH/LOW/LOLO: Alarm values
• Pub: Only used for array/list types, determines the subscription name for one or more PVs (a PUBLISH event is fired on each caput)
