Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://docs.videc.de/acron-9.3/en/anlagenkonfiguration/prozessanbindung/km_prozessanbindung.md). # Context menu The context menu contains the following options for the process connection: * Cut Cut an object * Copy Copy an object * Paste Paste a cut or copied object * Delete Delete the selection Note Referenced objects cannot be deleted. Exception: Usage in input masks, reports and diagrams does not block deletion. Note No providers whose external variables are used (referenced) by a process variable and/or entity can be deleted. No external variables linked to a process variable and/or entity variable can be deleted. * Provider Create a new Provider * Group Create a new variable group; Create a copy of the selected variables group as a subgroup * External variable Create an external variable * Export...\* * External variables... Export of the external variables to a .csv file. * External variables for renaming... Export of the external variables to a .csv file. * Import\* * External variables from file... Selective import of external variables from a .csv file. Note Existing external variables are overwritten and/or moved after a prompt. * External variables from other plant... Import external variables from a plant Note Existing external variables are overwritten and/or moved after a prompt. * External variables from control system... Import external variables from the running control system. For this the driver assigned to the Provider must support this function. Note Existing external variables are overwritten and/or moved after a prompt. * External variables from renaming... Import of external variables from a .[csv file](/acron-9.3/en/anlagenkonfiguration/prozessanbindung/aufbau-csv-datei-umbenennung-ev.md). Note Only the newly added changes are processed. * Process data from other plant... Import of external variable process data from a plant included in ACRON (also versions later than 8.5). Note A check is made for a matching identification of the external variable in the exporting and importing plant. Both external variables should use the same data type. The Database Engine should be running for the target plant. First select the plant from which to transfer the data. Then check whether there are external variables with the same identification in both plants. If so, the desired external variables can be selected in a further dialog. The data import then begins. * [References](/acron-9.3/en/anlagenkonfiguration/prozessanbindung/provider/providerid/variablengruppe/dialog_referenzierungen-auf.md)... Display the process variables linked to an external variable. Display the formulas used as appropriate. * Unused variables * Variables with enabled measured value archiving without assigned process variable... Display of all external variables for which measured value archiving is enabled, but with no process variable assigned to them, with the facility to delete single ones or all. * Variables with enabled service recording without assigned entity... Display of all external variables for which service recording is enabled, but with no entity assigned to them, with the facility to delete single ones or all. * Variables without enabled archiving/recording... Display of all external variables for which nothing is enabled, with the facility to delete single ones or all. \* Import and export are only possible from the main group folder. \*\* If the lettering in the context menu is in bold, you can also perform the action by double-clicking on the object. --- # Agent Instructions This documentation is published with GitBook.
