Generally, no particular engineering and programming is required on the controller side. In particular, it is not necessary to call up any program modules.
When using the PC/CP connection mode, you have to configure a suitable access point in the SIMATIC PG/PC interface on the ibaPDA computer, see Setting PG/PC interface/defining new access point.
Only for the LOGO! and S7-200 controller types, you have to configure an Ethernet connection in the control system, see Configuration of LOGO! and Configuration of S7-200.
