Description:
The address of the master depends on the number of
attached slave units (09 = master with 9 slave units). The
address of a slave unit always begins with a 1. The 2nd digit
represents the actual address. Up to a maximum of 9 slave
units may be operated with one master unit, whereby any unit
may be a master. The maximum overall length of all con-
nected units is 50 m. Single-phase and 3-phase units may be
connected.
