Transmission in Screen Units
The NT600S allows the transmission of data for individual screens. The screen
number of the screen to be transmitted can be specified with the support tool to
transmit this screen only to the NT600S (it is also possible to transmit multiple
screens in a batch).
If, when executing screen data transmission in screen units, there are also
changes to data other than screen data, for example memory table or direct ac-
cess data, transmit this changed data to the NT600S also.

Memory table
When screen data transmission is in screen units, if data other than screen data
changes -- for example memory table or direct access data -- transmit this new
data also.
When screen data is transmitted to the NT600S, it does not overwrite existing
screen data; it is written to a free area of the memory. Consequently, if data is
transmitted frequently in screen units, the free area of the memory will not be suffi-
cient and transfer will become impossible. If this happens, transmit the data in file
units to bring the memory of the NT600s back to order.
Transmitting the Screen Data from the Support Tool
To transmit the screen data from the support tool to the NT600S, connect the
NT600S to the computer on which the support tool is being used, and follow the
procedure below.
The NT600S (Host link/NT link/RS-232C method) uses one connector for the con-
nection to both a PC/Host and a computer. If it has been connected to a PC/Host,
disconnect the PC and connect the support tool (computer) to the NT600S, and
then, transmit the screen data.
Operation
1. Connect the NT600S to the computer on which the support tool is being used,
and turn ON the NT600S.
2. Turn ON the computer and start up the support tool.
3. Set the [Support Tool Mode] memory switch setting to match the support tool
being used.
