You only need to give the card its own power supply on pin 1 and 20. Have a look to the manual of the S7-300 modules, chapter 6.7: SIMATIC S7-300 S7-300 Module data to see what the SF means, have a look in the HW-config online or in diagnostic buffer. I guess it is a kind of wire break supervision. hope this helps, regards, |
