Onboard Editor
The onboard editor lets you create or edit messages, select message
attributes, and set options and variable formats on a Version 2.00 or later
DL40 message display using any of a number of standard keyboards.
Send ASCII Data to a PLC Via a Remote I/O Link
Using Remote I/O communications, you can send ASCII data to your PLC.
Simply attach an IBM compatible keyboard to the DL40 message display,
and you can enter parts numbers, badge numbers, and similar information as
required. The DL40 processes and displays the information, and then sends it
on to the controller.
You can enter bar code data using a wedge attached to an Allen-Bradley bar
code scanner. The DL40 displays scanned bar code information, then sends
the data to the PLC through the Remote I/O. Refer to Publications 2755-824
and 2755-824.1 for information on applications using Allen-Bradley wedges.
You can establish similar communications over an RS-485 link.
Communications with Any Programmable Controller (Parallel Port
Version)
The DL40 can accept information from any programmable controller over a
total of 20 input lines (16 data and 4 strobe lines).
Parallel Port versions of the DL40 also have a 12 VDC terminal that can be
used to power outputs that pull data and strobe lines high.
Backup Operations
You can archive DL40 applications files in a number of ways.
