REX 100 Ethernet Router

Assumed that a REX is connected to the myREX24 server 24/7 in idle, our tests revealed that it can demand up to 80 MB per month (also depending on the internet provider, 80 MB was the highest value that ever obtained in our tests).

As soon as a user connects to the REX via VPN or data values are logged via the REX, the data volume will be higher.

NETLink PRO

DP/DP-Koppler

There is no separate GSD file for the DP/DP coupler. The DP/DP coupler can be selected directly in the hardware configurator of the Simatic Manager or TIA-Portal under the Siemens order number "6ES7 158-0AD01-0XA0 DP/DP coupler, edition 2" and inserted into the project.

DP/PN Coupler

Answer 1:

When using universal modules, please note that they are only available on Profibus side. The picture of the DP / PN coupler web interface shows in red that in the 5 universal modules inthe first 3 slots no regular variables have been parameterized that are conform to the PN configuration. In this case, the SF LEDs on the DP/PNcoupler lights up and data transfer is not possible. The number of configured input or output bytes must match exactly with the other side.

Answer 2:

Depending on the application, consistent data transmission can also be selected for PROFIBUS. On the PROFINET side, all modules are always consistent, so that only the corresponding sequences and sizes (matching with the opposite side) must be observed.
