CHAPTER 5
PROTOCOL AND OPERATIONAL WORK
5-11
Displays for series DT-203NN, DT-105NN and DT-110NN
5. To transfer the messages to the display, press the icon
“Send
messages to the
Display
” and if everything is OK, we will see the
message” programming” on the display.
If this message does not appear, check that the COM port number on the computer is
correct, the state of the Null-modem cable and that the comunication parameters are as
indicated above.
Depending on the number of messages, the message recording can take few
minutes to complete.
3. Selection of messages by Profinet network.
Prior to sending data throught the Profinet network, we must change the display protocol
parameter to:
PROTOCOL
: PROFINET
The data block to select the message consists of 4 bytes.
Being %QBx, the first output address of PLC which we have configured the display module
and %QBx+1,..,%QBx+3 the address of the successive bytes.
B1,..,B4 Are the data bytes contained in these addresses, where:
B1: Most significant byte for the message number.
B2: Least significant byte for the message number
B3: Always 00h
B4: Always 00h
Example:
If we have a DT-203/2S-20 (2 lines and 20 characters display) and have edited,
throught TDLWin, the following message list:
Assuming that the same range of output addresses have been configured as shown in
Fig.12, which goes from %QB68..%QB147, the data frame to be sent is the following:
Show message number 0001:
%QBx
%QBx+1
%QBx+2
%QBx+3
