Hi all, having some issues with connecting to a S7 1500 PLC.
I can ping the IP address from my laptop which is running the factory studio project.
x.x.0.100 is the PLC IP address. x.x.0.225 is the laptop.
Channel is set to Siemens, Node S7PLC uses this channel (only channel configured), point is MW100 for an integer.
In the watch window I get a fault of -720868, but I cant find what this code means. I have looked in the Siemens connection PDF and it says a negative value is an internal driver error?
All help and suggestions appreciated!
Hi Bob,
In TIA Portal you can do some configurations to fix this error, you can check Section 5 in the following document:

I can read the values now Eduardo but I cant write to them. I have them set as read / write on the points page?
Scrap that found the issue…
We had this problem a couple month ago, and the solution for that was that the application was running in test. Can you confirm to us if you are running the application in Run>Test, or Run>Startup?
Sorry, we didn’t understand what you mean by “Scrap that found the issue…”

Hi Eduardo, apologies, Yes I found I was running in test not startup. Thank you.
