The S013-18 abend means the following:
S013-18 Empty PDS member, or PDS member not found.
Release : 12.2
Component : CA NetMaster Network Management for TCP/IP
There was a typo in the SXCTL DD member.
In the RUNSYSIN it is SXPCPL3
but in your update you have SPXCPL3
notice the 'X' and 'P' is reversed.
