Chapter 10. Configuring the I/O Driver from FIX/iFIX Applications163
DEVICE_NAME:ADDRESS[:BIT]
Where:
If you enter an I/O address not defined by a datablock, the driver performs one of the
following operations, if you enabled the Auto Create option:
• Adds a new datablock to the specified device.
• Extends an existing datablock to include the new address.
If you have not enabled the Auto Create option, Database Manager prompts you to
start the Power Tool so that you can add the nonexistent datablock to your driver
configuration. You can then continue configuring the database block.
NOTE: You are also prompted to start the Power Tool whenever you enter the name
of an undefined device.
Make sure the data type and the register size match. If they do not, the address is
rejected because the datablock being referenced does not align with an entire
register.
The driver optimizes the building of datablocks by automatically determining
whether to extend an existing datablock or add a new one. If you want to modify the
datablock default values, open the SI7 I/O Driver Power Tool and make the changes
to the configuration file.
DEVICE_NAME Is the name of the field device or process hardware that you
want to collect data from. This name must match the device
name in the driver configuration file.
ADDRESS Is a register in the device. For example, to access register
DB3,2, enter DB3,2 as the address.
BIT Is a specific digital point in the register. This entry is only
necessary for digital database blocks configured with the
BYTE data type. The SI7 driver accepts bit values from 0
to 7. You cannot access bits of digital database blocks
using any other data type.
