Pin assignment CPX−8DE−D with sub−base
CPX−AB−4−HARX2−4POL
On this sub−base only the sensor supplies for the inputs Ix,
Ix+2, Ix+4 and Ix+6 are available. These supplies are used in
pairs by the inputs Ix/Ix+1, Ix+2/Ix+3, Ix+4/Ix+5 and
Ix+6/Ix+7. The diagnostic messages are therefore only for the
inputs Ix, Ix+2, Ix+4 and Ix+6. The inputs Ix+1, Ix+3, Ix+5 and
Ix+7 do not generate a diagnostic message.
