4. Data Type Definitions

or all alphanumeric fields, HYDRA does not support specific special characters. Such as: “\“ (backslash), “|“ (pipe), “ “ “ (double inverted commas), and “ ’ “ (single inverted comma) since they cannot be entered into the shop floor terminals and will not be supported by MOC

The “;” (semicolon) character is used as separator and therefore must not be used in key fields

(e.g. order, batch number, personnel number, etc.).

The “%” (percent) sign is used as placeholder/wildcard character for database queries. Therefore, this character should

not be used as it might falsify results.

The file must not include byte order marks (BOM).

HYDRA expects always a comprehensive data structure. This means that unused data fields must be completed with such default values that comply with the applicable convention. This applies especially at the end of a data structure. The following definitions apply if file ports are used:

MES-Weaver 3.0

Each data record must be terminated by 'CR' (0D Hex) and 'LF' (0A Hex) under Windows and by 'LF' (0A Hex) under Unix.

The file is expected in the UTF-8 format and will be provided as such by HYDRA during confirmations/uploads. Upon request, it is also possible to realize the file transfer in another file format that is common up to MW 2.x.
