SSC Method List (CHG 2N/CHG 4N)
14.16 /device/language
Parameter type: String
Permission: Read/Write
Pre-condition: N.A.
Post-condition: N.A.
Description: User-settable value determining the language to be used for values returned by the
server which are meant to be displayed to the user. Examples are /osc/error/desc, /osc/limits/.../
desc, /osc/limits/.../option_desc.
An SSC Client can determine the possible language options by querying /osc/limits/device/lan-
guage.
Languages are encoded with 2-3-letter-codes as per the locale convention. Default language is Brit-
ish English, "en_GB".
Support for languages is optional. Restricted SSC Servers may omit description texts completely;
they should return an empty string for /device/language. Servers offering only one fixed language
should return that for /device/language, and refuse attempts to change it.

TX: {"device":{"language":null}}
RX: {"device":{"language":["en_GB"]}}
