Concept error: "Mapping of two 8-bit input modules consecutively in the 1x area without gap to the next 16 bit boundary is not allowed, if the I/O modules belong to different heads.."

Issue:
    Error: Mapping of two 8-bit input modules consecutively in the 1x area without gap to the next 16 bit boundary is not allowed, if the I/O modules belong to
different heads (Local, CRP811, CRP93x, NOMxxx).    If you do not follow this rule the Input-Bits of one module might be OVERWRITTEN by the other module.

Resolution:
  • Mapping 8 Bit modules in the 3X area OR
  • Mapping 8 Bit modules on a 16 Bit boundary
