Configuring process data

To transmit process data via an I/O connection, 2 static input assem-
blies and 1 static output assembly can be selected - for details,
see Operating Instructions, chapter "Configuring process data".
"Address" in the table describes the data attribute of the assemblies
for read access (class, instance, attributes).
Input assemblies Address
S1...S4 4, 1, 3
(Factory setting)
S1...S4 + POS 4, 2, 3
(with POS: Actual
position)
"Address" in the table describes the data attribute of the assemblies
for read access (class, instance, attributes).

10.9 Safety position of the solenoid
valves in the event of a bus error
If the bus fails, the solenoid valve is switched to a programmable
safety position (default: the solenoid valves are in the power-off
state) - for details, see Operating Instructions, chapter "Configuring
the device".
Bus failure is indicated via the central multi-colour status display
(for detailed information on the colour and blinking pattern - see
Operating Instructions, chapter "Blinking pattern / Fault signaling").
The bus status LED "Network" on the electronic module also indi-
cates whether a bus error has occurred - see Operating Instructions,
chapter "Display of the status LEDs in the event of a bus failure" or
"Status of the bus status LED "Network".
