2.4.3 Frames in data management and active frames
2.4.3.1 Overview
There are various types of frame: system frames, basic frames, settable frames and the
programmable frame. Apart from the programmable frame, all types have a frame in the data
management and an active frame. The programmable frame is only active. Frames in the
data management are stored in the static NC memory and can be archived. The program
can describe both data management frames and active frames. HMI can only describe data
management frames.
