Why is my Fanuc getting an Abnormal End error?

Problem

When trying to send a program from a Fanuc using FTP, an error pops up saying "Abnormal End".

Solutions

  1. Change the main program (active program) to something else. Then try again. 
  2. Confirm the machine is connected to the network by attempting to ping it from the Predator DNC PC
