78 Siemens Simatic S7 Driver Online Help

NOTE: A configuration file named nodename.SI7 is saved in the root

Dynamics directory when you install the driver. If you are using FIX, the file

resides in the Database path (C:\FIX32\PDB, by default). Do not delete,

rename, or move this file. FIX and iFIX use this file to load the driver.

If you do not enter anything in Default File Name field, then FIX or iFIX loads

a configuration called Untitled.SI7.

• If you specify a driver configuration file in the Power Tool and run the driver

with FIX 6 or later, FIX uses the configuration you have loaded, and NOT

nodename.SI7 or Default.SI7.

• The way you disable a poll record has changed. In a 6.x driver, you enter

DISABLED as the poll time. In a 7.x driver, you clear the datablock’s Enable

check box or enter DISABLED in the Primary Rate field.

• The datascope in a 6.x driver is either on or off for all channels, devices, and

poll records. In a 7.x driver, you can enable and disable the datascope for

individual channels, devices, and datablocks.

• With the S_7 6.x you can assign one connection to only one communication

processor-virtual field device pair. For example, if you assign the CP-VFD

pair, CP_443_1:VFD5, to the connection Device1, you cannot assign it to any

other connection, such as Device5 or Device10.

However, in the SI7 7.x driver, you can assign any connection to any

combination of communication processors and virtual field devices defined in

your SIMATIC NET configuration. For example, if you assign the CP-VFD

pair, CP_443_1:VFD5, to the connection Device1 you can also assign it to

Device5 and Device10.

To enable the datascope for a channel, device, or datablock

[1] Right-click the channel, device, or datablock you want to modify from the

Tree Browser.

[2] Select Datascope On from the pop-up menu that appears.
