My new hardware configuration for I/Os was not taken over by the xx7.

FAQ #100145

There are a couple of common causes for this case. Please take care of the points mentioned below.


There are basically three sources of errors:

  • After a change of the hardware configuration the PCD must change its state from "STOP" to "RUN" (Restart)

  • If the change was made manually directly in hardware-DB with LAD/STL/FBD-editor, remember that not the "Initial value" will be taken over after a restart of CPU but the "Actual value". Check this by using "Data view"-command in "View" menu of editor. 

  • The hardware-DB can have the number 1, 511 or 1023 and it is marked by the initial 4 bytes of type "CHAR" which must be "Mxx7". If more than one of these three DB's has this identification the DB with the lowest number is the representative one.
