Page 17: Functions
Functions 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. - Page 18 Functions 4.1 Cyclic and acyclic data exchange Cyclic data exchange: Control and status information The transmission of control and status information between the S7 controller and PN/M-Bus LINK is performed via the cyclic IO process image. In order to read measurement data from a specific M-Bus device, the S7 user program sets the control bit for the respective M-Bus slave in the cyclic output data from the value "0"...
- Page 19 Functions 4.1 Cyclic and acyclic data exchange Acyclic data exchange: Reading measurement data from M-Bus devices The measured values are transferred from the PN/M-Bus LINK to the S7 control system through data records.
