Obsolete syntax of macro expression:
- Obtains the value /data/webportnumber from the configuration file referred with the config identifier.
- Obtains the value /data/webportnumber from the configuration file referred with the config identifier. If the value is not found in the file, then the backup value 80 is returned.
- Obtains the value of /data/boiler1/webportnumber from configuration XML file registered as config identifier. The expression allows to read the value from arbitrary hierarchical level (the boiler1 level is extra here).
|Value identifier||Specifies the compound value identifier, e.g.: config/data/portnumber.|
|Enter substitutional value||It is used to define substitutional value that will be used in case the referred value is not found|
