Cause
A number of identifiers, numbers, and designations in EPLAN projects, such as the device tag, are managed by different databases. In individual cases, the input of very long sequences of letters and / or numbers can result in a cap on information in one of the databases and thus produce incorrect results.
Solution
Reorganize the project.
- Select the menu items Project > Organize > Reorganize.
- In the Reorganize project dialog, activate the Advanced mode check box, click [Yes], and wait until the reorganization process is completed.
- Then, start a new check run for the entire project.
Note:
The default field lengths of the identifying components of the device tag are often asked for.
Note that EPLAN supports the following number of characters:
- 16 characters for the prefix
- 16 characters for the identifier
- 64 characters for the counter
- 16 characters for the subcounter.
Keep the device tags as short as possible for the sake of an easy overview and to prevent errors.
