Transmitting the Screen Data
The screen data is created with the NT Support Tool and then transmitted to the
NT21. This section explains how to transmit the screen data.
For details on how to create the screen data and the operation of the NT Support
Tool, refer to the Reference Manual and the NT-series Support Tool Ver. 4.6 for
Windows Operation Manual (V061-E1-
j
).
Reference:
S
The screen data can be transmitted also from the Memory Unit installed in the
NT21. For details on this method, refer to 3-5 Using a Memory Unit.
S
The screen data can be transmitted at a faster rate by setting High for Baud
Rate on the Comms. Setting... window of the NT Support Tool.
S
If writing to the screen data memory is disabled by the setting made for System
Setting in the System Installer mode, screen data transmission is not possible.
The screen data comprises the following types of data.
•
User screen data (screen units)
•
System memory (memory switch) settings
•
Direct connection information
•
Numeral memory table data
•
Character string memory table data
•
Bit memory table data
•
Mathematical table data
•
Mark information
•
Image/library data
•
Recipe table data
It is possible to transmit the screen data (data for all the screens) in file units, or to
transmit individual data or the data of individual screens in data units. (It is not
possible to transmit mathematical table data in data units.)
When data is transmitted in file units, all of the screen data in the NT21 is cleared
and then the new data is transmitted.
When data is transmitted in data units, first the previous data is invalidated, then
the new data is registered as valid data. Since the previous data is not cleared,
free memory area in the NT21 will be insufficient when transmissions in data
units are repeated. If this happens, write the screen data again by data transmis-
sion in file units.
To transmit screen data from the NT Support Tool to the NT21, follow the proce-
dure below.
Operation
1, 2, 3...
1. Connect the NT21 to a personal computer in which the NT Support Tool has
been installed and turn the power to the NT21 ON.
2. Turn ON the power to the personal computer and start up the NT Support
Tool.
