Assigning a buffer module SITOP BUF8600
A buffer module permits buffering when the power fails. A SITOP PSU8600 basic device can
be equipped with a maximum of two SITOP BUF8600 buffer modules.
Buffer module versions
BUF8600 buffer modules with electrolytic capacitors:
●
Buffer time of 100 ms at 40 A, Article number 6EP4297-8HB00-0XY0
●
Buffer time of 300 ms at 40 A, Article number 6EP4297-8HB10-0XY0
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
●
STEP 7 in the TIA Portal has been opened and a project has been created.
●
A SITOP PSU8600 basic device 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 Supplies\SITOP PSU\PSU8600\BUF8600.
