Serial Port Protocol
When the DL5 is set to be triggered through the serial port, use the
following protocols to trigger messages and display variable data:
Message Trigger [Ctrl][T]
Use the CTRL-T command to trigger messages while the DL5 is in the
binary and BCD modes. The message number and address are decimal
values. The command has the following format:
where:
– Message Number is a decimal value in the range 1-999
– DL5 Address is a decimal value in the range of 0-127
For example, to trigger Message #123 on a DL5 with an address of 10, the
following string would be sent:
Note: If you need to trigger messages (Round Robin and Numeric modes),
with a PLC that does not support unsigned integers, refer to the application
note in Appendix D
Note: If the DL5 is in serial trigger mode and you attempt to download
messages using the offline programming software, data corresponding to a
message trigger command will be executed.
