I am an instrumentation student working on project that will hopefully
use both a barcode scanner and a panelview screen. Currently the
scanner is working and is connected to the PLC through the serial
port(RS 232) on the processor. I still need to interface with the
PanelView with the same PLC. Since the port is already being used with
the scanner, is there any other way to connect the touch screen to the
PLC? Thanks for the help.
A PanelView with a DH-485 interface could be connected to the other
port on the SLC-5/03.
A 1746-BAS card could be programmed to interface with the bar code
A Prosoft MVI46-GSC module could be programmed to interface with the
bar code scanner.
There are a couple of DH-485 barcode scanners on the AB encompass site:
Unfortunately, all these ideas cost money.
Look into a AIC+. I 'believe' the Allen Bradley Cat. No. is 1761-NET-AIC. A
cable will go from the -03 to the AIC+, which has two serial and a DH-485
To quote the AB knowledgebase,
Direct connection to a SLC Channel 1 of an SLC 5/03
To connect an RS-232 Panelview to Channel 1(DH-485) of a 5/03 processor use
cable from port 3 of the AIC+ to Channel 1 of the SLC and connect the
PanelView to Port 1 of the AIC+
using a 2711-NC13 cable.
Many Panelviews will talk DH-485 natively if configured to do so.
A BAS Card to your scanner would work too... but it isn't cheap and there
may be extra programming involved.
AIC+ units and cables are usually available on E-Bay pretty reasonably
For more info, go to AB.Com, support, and use the knowledgebase search
functions. I used AIC+ panelview slc to find the quote.
Email me if you need more help.... good luck!
