Diagnosis
Number of valves
that can be controlled
Number of
connectable modules
The bus coupler is designed only for use as a participant in a
DDL line.
A shielded, 5-wire cable is used as a fieldbus cable
(see DDL system description). The line length can be up to 40 m.
A maximum of 14 participants may be connected.
The bus coupler address is set with the S5 switch.
The baud rate can be set with S6, bit 1.
The logic and valve control power supplies are monitored. If
they exceed or fall below a set limit, an error signal will be
generated and confirmed with the diagnostic LED and the
diagnostic information.
Up to 12 double or 24 single solenoid valves or a suitable
combination of double and single solenoid valves can be
connected. In each case, up to 24 valve solenoids can be
controlled.

Input/output modules

Input/output modules with releasable plug connections allow
electrical input and output signals to be output via the valve
system's DDL line.
Input and output modules can be connected in any combination
on the valve driver (in the DDL line) – however, with a maximum
of 3 input modules and 3 output modules (total output signals
incl. valves may not exceed 32 outputs).
O
Make sure to stay within the load limits.
The bus coupler supplies the inputs for the input modules.
The maximum total current for all inputs is 0.7 A.
The output module is supplied via an M12 connection, with one
power supply each for 4 outputs (see Tab. 11 on page 83).
The bus coupler is limited to 4 bytes of output data and
4 bytes of input data due to system design. If 3 output
modules (3 bytes of output data) are used, there is only one
byte available for the valves, i.e. 4 double solenoid valves or
8 single solenoid valves can be controlled.
