1.2.5 System Interface
It is necessary to create a ladder logic program specifically for use as the Teach Pendant inter-
face, so that the status of the MP9jj-Series Machine Controller and the Teach Pendant sys-
tem can be managed.
User functions are provided for the interface ladder logic program. These functions must be
called every scan from both a high-speed diagram and a low-speed diagram.
There are a total of 15 interface ladder logic functions, and one of these is used in the high-
speed drawing and one in a low-speed drawing.
