Error LED Error messages are displayed on the one hand via the red LED
on the pneumatic interface and on the other hand transferred
from the pneumatic interface to the CPX bus nodes. These
error messages to and from the pneumatic interface can be
inclusively suppressed by parameterisation on the CPX ter
minal (module code: 70
d
).

Configuration of the address space
From the point of view of the CPX terminal the pneumatic
interface is seen as an electrical module with a variable
(configurable via the rotary switch) number of digital outputs
for the control of the attached valves
For a valve terminal MPA−L with CPX terminal a maximum of
32solenoid coils are controllable, independently of the posi
tion of the rotary switch (see Tab.3/8).
Note
On conversion or expansion of the valve terminal MPA−L
the number of output addresses assigned by the pneu
matic system via the rotary switch on the pneumatic inter
face must be checked and adapted if necessary.
This is not necessary if previously a sufficiently large ad
dress space for the expansion has been reserved.
