Solution
The activated command is not allowed since the scale is not yet
adjusted. Switch to service operation and adjust the scale.
The activated command is not allowed since the scale has a fault
or SIMATIC CPU is in STOP status. Correct the error (red LED
on the front must go off).
You have assigned the digital inputs incorrectly. Correct your
assignments.
You have assigned the digital outputs incorrectly. Correct your
assignments. The outputs may only be defined with numbers 0 to
63 and 255.
You have assigned the digital inputs incorrectly for enabling
weighing steps. Correct your assignments. In NAWI operating
mode, no step-on conditions can be defined.
The definition of the measurement time for the pulse input is
incorrect. The permitted range lies between 100 msec and
10000 msec. Correct your definition.
