Cyclic and acyclic data exchange
PN/M-Bus LINK is always the M-Bus master. The functions of the PN/M-Bus LINK enable
you to read measured data from connected M-Bus devices. To do this, the M-Bus functions
"SND_NKE", "SND_UD" and "REQ_UD2" are implemented in PN/M-Bus LINK. It is not
possible to configure or write to M-Bus devices.
