Alternative for SFC14 and SFC15

Hello,

I have an S7-300 CPU 315/2DP and wants to send data to a Profibus controller.
The problem is that this CPU the SFC14 and SFC15 not supported because the CPU is too old for this.
Since Consistent data (full length) for this controller to be used I am looking for an alternative.
Anyone have an idea?

Greetings,

SFC14 and SFC15 are working for this cpu!!!

What made you think they are not supported?

Not good reading of support documents on the
Siemens site!
