Transmitting the Screen Data
Section 6-6
6-6 Transmitting the Screen Data
The screen data is created with the Support Tool and then transmitted to the
NT31/NT31C. This section explains how to transmit the screen data.
For details on how to create the screen data and the operation at the operation at
the Support Tool, refer to Sections 7 to 9 of this manual and the NT-series Support
Tool Ver. 3.0 for Windows95/98 Operation Manual.
Reference - The screen data can be transmitted also from the memory unit installed in the
NT31/NT31C. For details on this method, refer to 3-5 “Using a Memory Unit
(NT31/NT31C with V1)” (page 46) or 3-6 “Using Memory Unit (NT31/NT31C
with V1)” (Page 57).
- The screen data can be transmitted at a faster rate by setting “High” for “Baud
Rate” on the “Comms. Setting...” window of the Support Tool.
- 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.
Screen Data Composition and Transmission Units
The screen data comprises the following types of data.
S
User screen data (screen units)
S
System memory (memory switch) settings
S
Direct connection information
S
Numeral memory table data
S
Character string memory table data
S
Bit memory table data
S
Mark information
S
Image/library 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”.
When data is transmitted in “file units”, all of the screen data in the NT31/NT31C 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 NT31/NT31C will be insufficient when transmissions in
“data units” are repeated. If this happens, write the screen data again by data
transmission in “file units”.
Transmitting Screen Data from the Support Tool
To transmit screen data from the Support Tool to the NT31/NT31C, follow the pro-
cedure below.
Operation 1 Connect the NT31/NT31C to a personal computer in which the Support Tool
has been installed and turn the power to the NT31/NT31C ON.
2 Turn ON the power to the personal computer and start up the Support Tool.
