hi all,

i am working tochange Sinamics drive time to UTC time format. (S120, Model: 6SL-3040-0MA00-0AA1)

DB2 is my Job list DB. DB5 is request DB to write parameter p3101[1]. DB7 is request DB to write parameter p3101[0]. I have written function FC2 to read PLC date n time and convert it to days n milliseconds. These values are written into DB5 and DB7 respectively.

I cant figure out why, the drive does not recognize parameter change everytime? I first set p3100 to 1, then enable job to write p3101[1] followed by p3101[0], Finally set ping signal. The change occurs but for few trials only! If i do it for multiple times, the response DB shows error message. I have tested it for other parameters (p3109, p3110) but they can be written multiple times. Is there any limitation to the number of times theparameters p3101[0..1] can be written? Or is there any specific procedure?

any information/suggestion would be appreciated.

Thanks.
