Appendix C. Plug & Go
Plug & Go allows storing the complete TWinSoft project into the micro SD card of
TB
OX
LT2.
When required, micro SD card must be inserted at the back
TB
OX
LT2
(see chapter 19.3).
Micro SD of max. 8 GBytes, formatted in FAT32.
As TWinSoft project, we mean all files, including TWinSoft compiled document with Web and Report files,
OS and even LINUX kernel; all ready to run in the RTU.
There are 4 ways Plug & Go can be used:
1. TWinSoft sends a project to
TB
OX
LT2
.
When TWinSoft sends a program to the RTU, all the files are sent and stored in the micro SD card.
This corresponds to a complete backup of the project on the SD card.
The advantage is that if you have to replace a CPU, you don’t need to send the program; you insert
the MMC in the new CPU and it will start with its program.
2. You insert an empty micro SD card in
TB
OX
LT2
.
The running application of
TB
OX
LT2
is not copied to the micro SD card. Only when TWinSoft sends
an application to
TB
OX
LT2
it will be copied into the SD card (see above).
3. You insert a micro SD card including a project in a CPU.
In case of differences between the content of the micro SD card and memory of
TB
OX
LT2
, SD card
has always priority.
Both programs are compared (dates are compared). When dates of creation of the program are
different, the project (including Webform, reports, OS, LINUX, ...) is copied from the SD card to the
CPU. It may up to 1 minute. DO NO RESET The CPU !
During the loading the LED “Run” flash at ½ Hz, indicating the program is stopped.
4. You program the micro SD card directly from TWinSoft.
A menu in TWinSoft allows storing the project to the SD card.
From the main menu “File” -> Plug & Go menu, TWinSoft compiles the complete project into a
directory called repository. You then copy this directory to the SD card using a Card Reader on your
PC.
The advantage is that you don’t need TWinSoft to program the RTU. You can distribute the SD card
to the field technicians.
