CHAPTER 5
PROTOCOL AND OPERATIONAL WORK
5-11
Displays of series DN-109NN, DN-119NN, DN-129NN and DN-189NN
ASCII data type
Using this mode, the numerical value must be sent in ASCII code. An advantage of this
mode is the control commands which can blink the information displayed or change the display
color.
In ASCII format you will send as many bytes as digits have the display plus the control
commands (bytes) that you use. The maximum buffer allowed is 20 characters so the data
transferred must be equal or less than this value.
In this mode, the first byte of the Profinet frame corresponds to the right digit on the
Display (frontal view). So, the byte sequence will be represented in the following way.
1. Display parameters configuration (ASCII Mode)
Using the equipment buttons, we will configure the parameter 1 with the value 05.
The remaining parameters must be configured according to the section 5.2.1.
2. Sending of characters sequence of the message by Profinet network.
The numerical value of each digit must be coded in ASCII and sent in the abovementioned
sequence. Some alphanumeric characters are valid to represent in 7 segments digits. The
following table sum up the characters accepted in this mode:
