System Manual – DOP11A Operator Terminals
Network Functions and Communication
Network functions in the terminal
File format Each measured value is stored in a line ending with a carriage return and a line feed:
[carriage return][line feed].
Syntax
A semicolon (;) is used as separator.
The file is completed with
"END" [carriage return] [line feed].
Only the number of curves available in the trend (no emptly fields) will be transferred.
In the following cases, "OFF" is included in the measured value and identifies an interruption
when acquiring the value.
When the terminal changes to run mode, a co py of the latest sample will be saved.
The copy is marked with "OFF". As soon as the terminal has received the valid value,
the new values will be saved without the "OFF" mark.
When the signal for trend activation is outp ut, a sample will be marked with "OFF".
When the signal is output, a new value is saved without the "OFF" mark.
When the stored value is transferred using FT P or HMI-Tools, a sample will be saved
marked with "OFF". After the transfer is complete, a new value will be saved without
the "OFF" mark.
Library [IMAGES] For DOP11A-50 only.
The DOP11A-50 terminal also includes an [IMAGES] library. You can save graphics in
BMP format in the library. Bitmap graphics can be displayed in static symbol objects
when the terminal is in run mode.
Files in this library can be written, overwritten and deleted. It is not possible to create
new sub-libraries. If you activate the [Use dynamic bitmaps] checkbox for a static symbol
object, the terminal will retrieve the specified bitmap file (namn.bmp) from the [IMAGES]
library in the terminal's file system. In run mode, the bitmap graphic will be displayed on
the terminal screen.
The graphic to be displayed must be transferred to the library via FTP. You can add,
exchange or delete dynamic bitmap graphics via FTP by overwriting, saving or deleting
BMP files in the [IMAGES] library. The image for a dynamic bitmap graphic object is only
diplayed on the terminal in run mode.
The bitmap graphics are not available in HMI-Builder and can therefore not be displayed.
Use the same X and Y size for the BMP graphic in the library and for the symbol object
defined in HMI-Builder.
Files cannot be accessed from the [IMAGES] library.
When a BMP file is sent to the [IMAGES] library, transfer is stopped briefly for the
duration of time the terminal converts the standard BMP format into the special BMP format
of the terminal.
