Connect the CP 541 as follows.
We recommend the use of a SITOP power supply unit. If you do not use a
SITOP power supply unit, you must use a safety-separated power supply
meeting the requirements given in Appendix A.
Connect the supply of power (24 VDC) to the three screw terminals on the
CP 541. Ensure correct polarity.
Connect the CP 541 and the programmable controller with the preassembled
connecting cable (see Table 3-1).
Observe correct connector assignments.

You connect a programmer (PG) for parameter assignment or to evaluate the
diagnostics block, instead of the programmable controller, to the PG/PLC
connector of the CP 541.
Connect SINEC L2 to the 9-pin subminiature D female connector of the CP
541. Use standard components of SINEC L2 (see the manual: SINEC
L2/L2FO Network Components, 6GK1 970-5CA00-0AA).
