INVALID OR NONEXISTENT USER FAULT ROUTINE VALUE

Allen-Bradley · MicroLogix 1400 Programmable Controllers

Was bedeutet 0028 ?

A fault routine number was entered in status file S:29, but either the fault routine was not physically created in the program, or the entered file number was less than 3 or greater than 255. This is a non-user fault, preventing proper fault handling.

Häufige Ursachen

  • File number in status file S:29 points to a non-existent subroutine file.
  • File number in status file S:29 is outside the valid range (3-255) for user program files.
  • Typographical error when entering the fault routine number in S:29.
