Communications Using the Direct Connection Function
Communications Using the Direct Connection Function
The communications method applied between the NT and the PC is either a Host
Link or NT Link.
The NT30/30C can be used to access data for the display or to allocate the bits
and words for storing input data in essentially any area in the PC. The NT30/30C
can directly write and read the allocated bits and words to change the display ele-
ments, control operating status, and notify status.
This function is called the direct connection function. The NT30/30C is designed
specially for use with a direct connection.
The bits and words allocated by the direct connection function are called allo-
cated bits and allocated words.
A direct connection enables reading the data to be displayed on the NT30/30C
from a memory area in the PC and writing it to a memory table in the NT30/30C.
Also, the data input at the NT30/30C can be written to a PC memory area. The
NT30/30C screen status can be switched according to PC memory area data,
and NT30/30C status data can be written to a PC memory area.
The direct connection function allows the NT30/30C to directly read and write al-
most all bits and words in the PC and to automatically change the NT30/30C
screen display. This function can reduce the load on the PC to improve the pro-
gram development efficiency of the PC.
