CHAPTER 24
The frames necessary to carry out these functions are included in section 24.2.1,
"Read Holding
Coils" and

TCP/IP Protocol

To use the TCP/IP protocol, the communication port must be properly configured (See
section 24.1).
In order for the device to display a frame, this frame must be terminated with an end of
frame that is recognizable.
The last character sent is displayed to the right of the display.
The communication port is set automatically but can be changed at any time.
The display will be able to receive decimal numbers and ASCII characters. Once the
desired values are sent, there are certain control parameters to modify the color, the luminosity,
and the blinking. These parameters must be sent AFTER the values to be displayed.
Color

"X0" or "x0"
Red
(7830h o 5830h)
"X1" or "x1"
Green
(7831h o 5831h)
"X2" or "x2"
Yellow
(7832h o 5832h)
"X3" or "x3"
Orange
(7833h o 5833h)
Example:
The following table shows some examples combining numeric values in ASCII format and
control parameters.
%QBx %QBx+1 %QB x+2

36h 2Eh 34h
(7) In monochrome or color equipment set to red by default
(8) Blinking value
(9) Setting the color of the digits with the control command.
*For PLC, %QBx corresponds to a certain position in the output address space, from that
address the values must be consecutive.
