Checking and compiling the configuration
Checking / adapting I/O addresses
If necessary, you must adapt the I/O addresses assigned automatically by the TIA Portal.
This is possible, for example, in the "Device overview" window. Here you can also find the
I/O addresses used by the slots. The addresses assigned to slot 1, i.e. the PN/M-Bus LINK
(Master) are especially important, since the control and status information is exchanged with
the S7 program through them.
Checking the configuration
You can check the consistency of the configuration with a subsequent compilation.
Controlling PN/M-Bus LINK via the S7 user program
To enable data to be transferred between the S7 controller and PN/M-Bus LINK, you need to
set the control information via the S7 user program accordingly. This control information is
cyclically transferred from the S7 controller to the PN/M-Bus LINK. You can find detailed
information on this in the section Cyclic and acyclic data exchange (Page 15).
