Direct Connection Function

1-5 Direct Connection Function

The communication method applied between the NT11S and the PC is either a
host link or NT link.

The NT11Scanbe used to refer to the contents necessary for the displayinforma­tion or to allocate the bits and words used for storing the input data to any area in
the PC. TheNT11S candirectlywriteand readsuch allocated bits andwords soas
to change the display elements, control the operating status, andnotify the status.

This function iscalled the “direct connection function”. The NT11S is designed ex­clusively for use with the direct connection.

The bits andwords allocated by thedirect connectionfunctionare called“allocated
bit” and “allocated word” respectively.

This function allowsto read the information to be displayed on the NT11S from the
memory area in the PC and to write it to the memory table in the NT11S. Also, the
data input on the NT11S can be written to the PC’s memory area. The NT11S
screen status can be switched according to the PC’s memory area, and the
NT11S’s status data can be written to the PC’s memory area.

Features of the Direct Connection Function

S The bits andwordsreferring to operatingstatus andwork instructioninformation

and those for storing input data can be freely allocated to almost any part of the
PC memory. Bits andwords inthe PCcan bereferenced fromany memorytable.

S The NT11S can directly refer to PC bit and word data sothat it canbeconnected

to a PC without changing the PC program which controls currently running pro­duction line.

S The area to control and notify the NT11S status, including display screens, ON/

OFF of the backlight, and printing of daily reports and display histories, can be
freely allocated to any part of the PC memory.

The direct connection function allows the NT11S to directly read and write almost
all bitsandwords in thePCand toautomatically changethe NT11S screendisplay.
This function canreduce the load on the PC sothat the program development effi­ciency of the PC improves.
