7.4 SIMATIC STEP 7 in the TIA Portal
BUF8600 buffer modules with double-layer capacitors:
● Buffer time of 4 s at 40 A, Article number 6EP4293-8HB00-0XY0
● Buffer time of 10 s at 40 A, Article number 6EP4295-8HB00-0XY0
Note
It is possible to use different buffer modules in one system. This means, for example, that a
buffer time of 10300 ms (10000 ms + 300 ms) can be implemented. The number of buffer
modules that can be configured is limited to two.
Preconditions
● SIMATIC STEP 7 in the TIA Portal has been opened and a project has been created.
● A SITOP PSU8600 basic unit has been integrated in the project.
Procedure
1. Select the SITOP PSU8600 in the Device view.
2. Navigate in the Hardware catalog to the buffer modules under "Power supply and
distribution\Power supplies\SITOP PSU\BUF8600".
3. Select the required buffer module in the Hardware catalog.
In the "Information" area you can then see information about the buffer module. If
necessary, change the version that was preselected.
4. Drag and drop the buffer module in the Device view.
Alternatively, the buffer module can also be added by double-clicking on the entry in the
Hardware catalog.
5. Drag the buffer module to the required slot to the right next to the SITOP PSU8600.
The buffer module is inserted into the selected slot.
6. Save the hardware configuration.
You have assigned a buffer module to the basic unit.
