4.3.3 Input module CPX−8DE−D with channel diagnosis
Pin assignment CPX−8DE−D with sub−base
CPX−AB−4−M12x2−5POL (−R), CPX−M−4−M12x2−5POL
On these sub−bases only the sensor supplies for the inputs
Ex, Ex+2, Ex+4 and Ex+6 are available. These supplies are
used
in pairs by the inputs Ex/Ex+1, Ex+2/Ex+3, Ex+4/Ex+5
and Ex+6/Ex+7. The diagnostic messages are therefore only
for the inputs Ex, Ex+2, Ex+4 and Ex+6. The inputs Ex+1,
Ex+3, Ex+5 and Ex+7 do not generate a diagnostic message.
I−module type CPX−8DE−D with sub−base CPX−AB−4−M12x2−5POL (−R), CPX−M−4−
M12x2−5POL
Sub−base Pin assignment X1, X2 LED Pin assignment X3, X4 LED
