Parameter Access
This driver provides access to Data Tables defined in the Unitronics device. Data Tables must also be configured within the database. This is accomplished by clicking on the “Manage” button in the device configuration. Please ensure that each Data Table and Column Data Type defined in the database is consistent in size to that configured in the Unitronics database as correct data transfer is dependant upon it. Note: arrays assume 1 element per data table cell. String arrays are not supported. Refer to the table below for compatible data types.
| **Red Lion Column Data Type** | **Compatible Unitronics Data Type** |
|---|---|
| Bit | Boolean of 1 element only |
| Byte | Boolean of up to 8 elements |
| Byte | |
| Word | Boolean of 9 to 16 elements |
| Byte of 2 elements | |
| Integer | |
| Unsigned integer | |
| Long | Boolean of 25 to 32 elements |
| Byte of 4 elements | |
| Integer of 2 elements | |
| Long | |
| DW | |
| Real | Float |
| User Defined | String * |
| Boolean elements consistent with size | |
| Byte elements consistent with size |
- tag string length should be set to a value of at least 80.
After a table is created, it will appear in the address selection dialog box.
Note: If tables/columns are created and/or edited after mapping has begun in the database, it is recommended that the “Validate All Tags” utility located in the “Tags” category is run to update existing mappings.
Note: Columns of a data table that is defined as “Part of project” within the Unitronics configuration should not be created within the database.
