The Gateway Unit has a
built-in terminal resistor, so
connect the terminal resistor
at the end of the SIO
communication line.

SDA SIO communication line A Align the potential level of the
connected controller or ERC
actuator with the potential level
of the GND (ground).

The connection plug should
be a D-sub, 9-pin connector,
but this plug is not supplied.
With ProfiBus, a terminal
resistor*1 must be
connected to both ends of
the trunk line. For details,
check the operation manual
for the master (PLC).
