Module Messages - Data Orchester

Every message a module can put into its warning, info or error variable, with the level that decides which of the three it lands in. The texts are English in every language: they are values a plant writes into its own variables, and a peer, a dashboard or a mail template reading them must find the same words everywhere.

A {name} in a text marks where the module substitutes a value — an address, a register, a count. The Code is an internal identifier: it is never written into a variable and never appears in a message, and it is here so that a message whose wording improves can still be recognised as the same condition.

A code has one row per sentence. Its first row is the general sentence, which a module writes when it has nothing more specific to say; the rows after it are the other sentences modules write under the same code. The Modules column names the module types that write each sentence, or all when the engine writes it for every type.

See Status and messages for how the variables are assigned, and Connectivity for what each status means on a link.
