158 Siemens Simatic S7 Driver Online Help

To configure the driver from Database Manager, you must know the following

information about the driver:

• The three-letter acronym for the driver. For the SI7 driver, the acronym is SI7.

• The names of the field devices or process hardware that you want to collect

data from, as defined in the driver configuration.

• The registers in the device that you want to collect data from.

• The type of signal conditioning you want to apply to the data.

• The specific digital point in the register you want to access. This information

is only necessary for digital database blocks configured with the BYTE data

type. The SI7 driver accepts bit values from 0 to 7.

Datablocks are automatically created for devices that already exist in the Power Tool

when the Auto Create option is enabled. Devices are not automatically created.

Remember that the Driver field in Database Manager accepts the three-letter driver

acronym. The I/O Address field uses the device name assigned in the Power Tool

followed by the location in the device.

Refer to Entering Driver Information in Database Manager for details on entering

driver data in Database Manager for automatic datablock creation.

IMPORTANT: Always stop any 7.x driver you have running before you import a

database, reload a database, or create multiple database blocks with the Generate

command. If you leave the driver running while you complete any of these tasks, the

database may not load or import properly, or you may have to restart FIX/iFIX or

Database Manager.
