MODBUS Master
Addressing of the members that are activated via the MODBUS Master interface.
Addressing can be done automatically by a patented method. It is then no longer necessary to
address every single member manually in the network.
Alternatively, manual addressing is possible, for which separate components are required for setting
the individual member address.
Information

A
maximum of 32 devices
can be connected. The communication settings are pre-set to 19.2kbd,

(by a potential-free contact) is no longer active.
