17 SYSTEM LADDERS AND USER LADDERS
A ladder program has a system ladder in the system section and a user ladder in the
user section. Because the manipulator may not move properly unless the system
section is correctly edited, general users cannot edit the system section as well as the
XRC. General users can edit only in the user ladder section. (Contact your Yaskawa
representative when editing in the system section of the ladder program is required.)
