SINUMERIK 840D sl/840D/840Di/810D HMI Installation and Start-Up Guide (IAM) – 08/2005 Edition
A screen form, which calls another screen form but remains open
when the second screen form is displayed is known as a master
screen form. A screen form called from a master screen form is
known as a sub-screen form.
The advantage of the MSx parameter is that when screen
forms are replaced, they do not have to be reinitialized every
time because the data and layout of the current screen form
are retained and data transfer is facilitated.
The current screen form (master screen form) is interrupted
when the LM function is activated, the new screen form
(sub-screen form) is loaded and displayed. On EXIT, the sub-screen
form is terminated and the program reverts to the interruption point
of the master screen form. The UNLOAD block is not processed in
the master screen form on interruption.
Default setting: 0
