Your PLC is probably an S7-313C or S7-314C.
Next time remember to specify exact type numbers.

To use the onboard counter on a 313C, read chapter 5 in this manual:
SIMATIC S7-300 CPU 31xC Technological Functions

"On-board" means it is integrated in the CPU. The 315-2DP does not have any integrated I/O.

You have to add a counter card, either in the S7-300 rack, or via DP or Profinet.
