I am about to fit a TP177B to a S7-300 CPU313 and want to be able to connect to both the CPU and HMI at the same time, is this possible with this combination. I want to avoid having to unplug the HMI to program the PLC. If it's possible can you let me know what cables I would need.

Thanks in advance

The TP 177B can have MPI, Profibus DP or Profinet interface.
Assuming that you will have the MPI or DP variant then you set the PLC address as 2 and set the HMI as address 3 (using winccFlex) connect the HMI to the PLC with profibus cable and connectors.
At the PLC end use a connector with a pg socket.
This connector will allow you to "piggy back" your laptop interface cable to the PLC / HMI

Assuming that you will have the MPI or DP variant then you set the PLC address as 2 and set the HMI as address 3 (using winccFlex) connect the PLC and HMI with a "pass through" connector on the PLC.
This connector will allow you to "piggy back" your laptop interface cable to the PLC / HMI

Do you have a part number for the pass through connector?

Thanks

Check with your supplier they may have newer versions now.

The last bunch we ordered (a couple of months ago) were 6ES79720BB600XA0.

The last ones I used were Brad Harrison ones, they come with diagnostic led's in the plugs
