There's a CNC machine with Siemens hardware raising an error. It says the SINUMERIK 810D cannot connect to the controller. It used to take ten minutes, then half an hour, now it's not working. The S7 is giving a SF alarm, I need to connect to it to see what's the cause, but I'm an Omron guy so I need some help in this.
This is the S7. It's mounted to the right of a Siemens power supply, all good, tested.
I have the MPI adapter that works with the S7-300 with native serial port, but obviously here it doesn't fit. I have no idea if just a getting a new cable for the adapter will work. I don't even know if one can connect to this. I'm getting a vibe this is a only coupler for the SINUMERIK to use remote IOs.
