F.3.5 Definition of the configuration data set for a ‘Radio Slave’
The configuration data set defines the number of data bytes, which are cyclically transmitted
via the Profibus. This number of bytes can be variable adjusted to the scenario the Smart_DP
for Radio Modem Series – module is used for.
On the whole, the Smart_DP module allows a maximum data input of 30 bytes and a maximum
data output of 30 bytes. According to the max. ‘Radio Slave’ stations which the ‘Radio Master
system could be handled. (Actually a maximum of 8 units, other options on request)
Thus, the configuration of the number of bytes is integrated as a modular concept. By using
different radio slave modules (each one corresponds to a special number of DI/DO mark) – the
maximum is 30 bytes – the necessary length of input and output data can be defined.
Important note:
These defined settings (configuration data set) are sent by the Profibus master during
network startup.
