The bus coupler is designed only for use as a participant in a
PROFIBUS DP according to EN 50170 Part 2.
A twisted, shielded pair of wires is used as a field bus cable. The
bus length can be up to 1.2 km (without a repeater) depending
on the transfer rate. Without a repeater, 32 bus participants
(slaves) per segment are connectable. With repeaters, this can
be expanded to up to 127 bus participants (slaves).
The bus coupler's address is set using the S1 und S2 rotary
switches.
The bus coupler is automatically set to the bus speed between
9.6 kBaud and 12 MBaud.
The supply voltages for the logic and valve control are
monitored. If the valve supply voltages fall below a set limit, a
diagnostic signal will be generated and reported via the
diagnostic LED and the diagnostic information.
The bus coupler is available with 32 valve outputs. This limits
the maximum number of controllable valve solenoids.
Either 16 double solenoid or 32 single solenoid valves can be
controlled in this manner. The valves can also be combined.
A bus coupler with 32 outputs can only be connected to a VS that
has been designed for 32 valve solenoids.
