3.2 Interfaces
The two 16-pin plug connectors PLC OUT and VALVES are keyed so they cannot be
interchanged. For the PLC OUT, coding tongues are inserted on the pins 1 and 16,
for the VALVES connector, the tongues are on the pins 3 and 14.
3.3 Operating options
The Modul1000 can be operated via the control unit for desktop operation or the
control panel for the installation in a switch cabinet.
The Modul1000 provides an extensive software menu which serves for operation and
configuration (refer to
6.11 Menu structure ). This control unit offers access to the
menu structure.
The control unit can optionally be connected to the Modul1000 via 1 m or 5 m long
connecting cables.
The control unit is for configuring and controlling the Modul1000 individually and
parameters as well as measured values can be read out.
