Connection block diagram
The figure below shows an S7-300 assembly with CPU 313, 314, 314 IFM, 315,
315-2 DP, 316-2 DP, 318-2 DP and floating reference potential. If you do not want
to ground reference potential, remove the jumper on the CPU between the M
terminal and functional ground. If the jumper is not installed, the reference potential
of the S7-300 is connected internally to the protective conductor over an RC
network and the profile rail. This discharges radio-frequency interference current
and avoids static charge.
