The device ranges listed in the "Supported Devices" section are the maximum setup ranges. The ranges may be smaller than illustrated, depending on your PLC type. For further details, refer to the corresponding Device/PLC manual.
BLUE supports the following data types.
| Bit size | Character String | Signed | Unsigned | Float | String | Date and Time |
| 1-bit | BOOL | - | - | - | - | - |
| 8-bit | BYTE | SINT | USINT | - | STRING | - |
| 16-bit | WORD | INT | UINT | - | WSTRING | - |
| 32-bit | DWORD | DINT | UDINT | REAL | - | TIME TIME_OF_DAY (TOD) DATE DATE_AND_TIME (DT) |
| 64-bit | LWORD | LINT | ULINT | LREAL | - | - |
The usable device address range depends on the bit size. For the address range, see the corresponding Device/PLC Manual.
When the External device is an 8-bit device:
1-bit: Corresponds to the Bit Address range
8-bit: Corresponds to the Word Address range plus 1
16-bit: Corresponds to the Word Address range
32-bit: Corresponds to the Word Address range minus 2
64-bit: Corresponds to the Word Address range minus 6
When the External device is a 16-bit device:
1-bit: Corresponds to the Bit Address range
8-bit: Corresponds to the Word Address range
16-bit: Corresponds to the Word Address range
32-bit: Corresponds to the Word Address range minus 1
64-bit: Corresponds to the Word Address range minus 3
When the External device is a 32-bit device:
