communication cable

LRC · Oct 2, 2003

I would like to know what cable to use when I'm trying to communicate to an AB 5/03 from my laptop. Do you have to use a PIC box ? or can you use just a cable from the serial port to the processor. I have RS linx lite and RS logix 500 Installed on my lap top.

You can use a PIC on DH485, or alternatively the 5/03 and 5/04 both have RS232 ports (DF1). Either purchase the Bradley lead (1747-CP3), or make your own.

Female 9 Pin D-type plugs.

Pin 2 ------ 3
3 ------ 2
5 ------ 5

Hope this helps.

5/03 does not have rs232 port, you need PIC.
1747-cp3 or 1756-cp3 will NOT work with 5/03!

BTW correct pinouts for CP3:
2 ----- 3
3 ----- 2
4 ----- 6, 1
5 ----- 5
6,1---- 4
7 ----- 8
8 ----- 7

Look at www.plccables.com

The SLC 5/03 does support 232. See Publication 1747-6.2 for more details.

If you intend to use the DH-485 protocol for communication, you can (instead of the PIC) try something like the 1784-PCK communication card.

Maybe we have different Allen Bradley PLC's

in the UK?!!!

The SLC5/03 does indeed have a serial port (channel 0).
The other port is for DH485 (channel 1).

Kidblues cable description is OK, I use the same simple wire connection (2 to 3, 3 to 2, 5 to 5) when we make a serial cable for the SLC5/04. By the way, you can also buy a commercially available cable, it will be called a 9-pin to 9-pin "NULL Modem" cable.

Maybe the confusion is caused, because channel 0 can be set up for several protocols (DF1 full duplex, DFI half duplex, DH485, ASCII).
To use it for programming with only the serial cable, it must be set up for DF1 full duplex.

Looks I was not correct, SLC5/03 does nave Channel0 RS232 port. Sorry for confusion...

Hi

the easy way to connect PC to SLC 500 3/03 get 9 pin data transfer

cable you can get it in Office Depot or Office Max or in any computer store in abuot 10-15 US $.You can use it with NET-AIC too.

Buy an AB CP-3 cable or make/buy your own null modem cable for channel 0, can use PIC on channel 1 on 5/03. Unsure why they would make any different PLC for use in th UK!

Thanks

Thanks for your help guys.

Maybe the confusion about the 5/03 is that it only has one connector on the front of the card. I believe the 5/03 defaults to DH-485 out of the box and the only way to make it talk DF-1 (serial) is to first connect to it via DH-485 and change the port to DF-1. The port can't use both protocols at the same time.

well, actually the SLC-5/03 has two ports ... this book might be a good reference to stick in your "favorites" menu ...

SLC hardware manual

chapter 5 shows all of the various SLC processors and lists the features of each one ...
