2. Inputs:
The address assignment of the inputs does
not depend on the outputs.
2.1 Address assignment of the input modules:
• Addresses should be assigned in
ascending order without gaps.
• Counting should begin on
the node from right to left.
• Counting on the individual
module is from top to bottom.
• 4-input modules occupy 4 addresses.
• 8-input modules occupy 8 addresses.
2.2 Status bits
The addressing of the status bits depends on
the output fittings and on the configuration.
The following always applies:
•
The status bits are only available when input
modules are connected to the terminal and
when at least eight inputs are configured in
the PLC.
•
Addressing. The status bits are transferred
to the four highest positions on the con-
figured address range.
When the operating voltage is switched on, the
valve terminal automatically recognises all avail-
able pneumatic modules (type 03: max. 13
modules; type 05: 4, 8 or 12 valve locations) and
digital input/output modules and assigns the
appropriate addresses. If a valve location re-
mains unused (blanking plate) or if a digital
input/output is not connected, the appropriate
address is still assigned.
