After configuring the fields, the data server (Access), and table name in a historic, I click Generate Table and the following error message is displayed:
Table structure (title of the error window)
Table structure cannot be generated in the Database.
The following message was returned by the Database:
ErrorLocal = Create Table Error
Error #0x80004005
Description: Excessive number of fields defined
(Source: Microsoft JET Database Engine)
(SQL State: 0190)
(NativeError: -68092944)
How can I fix this?
Solution:
Access databases accept a maximum of 255 fields. This means E3’s historic will accept no more than 127 fields (127 fields + 127 quality fields + 1 E3Timestamp). In this example, you will have to split the historic in two (2 tables).
