PROTOCOL AND OPERATIONAL WORK
Displays for series DT-203NN, DT-105NN and DT-110NN
5.2 Operational modes
As mentioned, previosly, this display has two working modes “Selection by code” and
“Control by direct message”. Let’s detail how it is configured and operated in each operating
mode.
5.2.1 Code selecting
In this mode we will work sending a data frame throught the Profinet network that will
contain a certain message code stored in the internal memory that select and display the
message. To work in this mode, we will follow the next steps:
1. Configuration of the display parameters.
Enter to parameter configuration using the display keys (section 4.2.1) and adjust the
following parameters:
CONFIG: 001
PROTOCOL: TDL (Used only to storing messages in the equipment)
2. Upload of the messages to the internal memory of the equipment
To load the message to the display, it is necesary to use a computer with
WindowsXP/7/8/10 operating system and the “TDLWin” program specifically designed for the
programming of these displays. TDLWin program is available at our website for free.
All the displays have pre-programmed default factory messages. If you change them,
please remember that at least one message must be defined (message 0), which is displayed
by default after the equipment power on.
To program the messages the following actions must be done:
• Connection: Connect a Null-modem cable between the computer and the
display as it is described at section 3.3.
• Display: Select the “Configuration” parameter in the display “See section
4.2.3.2) and configure the “TDL” protocol.
• Application TDLWin:
1. Go to the “Configure” option.
2. In the “Display” window, select the “family” and “model” of the
equipment to be programmed. This will determine the number of lines
available by each message code.
3. In the “Serial line”, select the port where the Null-modem cable is
connected, and configure the following parameters:
Speed: 9600
Data Bits: 8
Parity: Par
Stop Bits: 2
4. Edit messages (There are icons that allow quick insertion of special
commands for message blinking , date or time information
or temperature and humidity measures in displays with this
option).
