Simatic manager defaults to TCP/IP - >Intel etc

I want to connect the programming PC to the Safety PLC using a USB to MPI/DP cable. I know the cable works as I've used it before. All the lights come on. I set the interface to PC Adaptor(Auto). I also tried MPI and Profibus. But when asked to select the download device, I can't see it on the accessable nodes. Significantly (and I don't know if this is an indication of the problem), when I exit from the hardware configuration, it automatically defaults back to the TCP/IP interface.

Try with the same adapter and PC, but a different PLC.
And try with the same adapter and PLC, bit a different PC.

Is the PG part of the configuration in Netpro?

do you have MPI enabled on your PLC? might have configured it for Profibus?
also, do you have any HMI connected to the same port? sometimes this gives trouble..

If you're asking if the programming device is part of the NetPro configuration - yes.

You'll have to tell me. Programming device isn't shown but it connects to the Industrial Ethernet only.

Going to try these things next week. Have to wait for a scheduled stop.

In NetPro, What network is the PG connected to?
The Netpro configuration will overwrite the PG settings.

Pg?

PG = programming terminal.

The programming terminal is connected to the ethernet only. If it had a profibus card, I wouldn't have these problems.

If the PG is in the Netpro configuration for the project, it's configuration in Netpro will override your PG settings.

I tried it with another PC, and still the same. I didn't want to try to connect with another PLC.

Continued to do some research, and started by checking the accessible nodes, where I was able to see the safety PLC. Shown here as SIMATIC 300.


Properties as shown here


I don't know how it does this, because it currently doesn't have an ethernet connection. Something to do with the routing?

So I turned the PLC off. Installed the ethernet card, and powered it up. The PLC goes into stop mode.
In the hardware configuration I inserted the new card into slot 7 of the main rack (which matches the physical configuration)and set up MAC address, IP address, gateway etc.

Did save and compile ok, then clicked download. Was offered a choice of accessible nodes to download to, and chose the one based on the properties I initially found.

It did a few things and then gave me this message about online and offline not matching. I know that the information shown here is garbage. Nowhere in any configuration, or physically, does the online module shown exist.


Clicked ok, and it proceeds as if it's going to download, before getting an error message.


The details of which are.


This is deeper than I ever expected to delve into a Siemens (or any) PLC.
