ETHERNET COMMUNICATION

Fig. 103: Frame in MODBUS/TCP to display the value "
-3270
".
These frames show the sending and response explained in the previous section.
24.2.2.2
Register 06.
It is important that in this case the
starting address
is 6.
This register is used identically to the previous one, but it is used for numeric values of
type WORD without sign. The range is from 0 to 65535. Color and lightness are handled
identically.
For example, the same frame is sent as in the register 02 example, but the starting
address is changed to 06. In this case, 62266 is displayed, if the device has 5 digits or more.
Otherwise the display shows “OvL”.
24.2.2.3
Register 10.
It is used to send numeric values of type double WORD with sign. The range of values is
-2,147,483,648 to 2,147,483,647.
You have to send between 6 and 8 bytes of information, the
starting address
being 10.
The first four bytes indicate the value to display (in two's complement). The next two
modify the position of the decimal point. The last two (optional) the color and brightness of the
display.
The color and luminosity values work identically to the previous cases.

For monochrome displays the color selection byte can be used to manage flicker. Typing 08h starts the
flashing, 09h ends it.
Example:
To easy the information sending,
