ControlLogic 5550

Hi Buddies,

I konw a little bit about A-B SLC 500 PLC programming, but this time I met a ControlLogix 5550 PLC with Ethernet and Controlnet modulars. It's a good chance for me to learn more. The problem is how I can access the program in CPU:

1: Can I use Rslogix 5000 to read the program through a RS232 cable used in a SLC5/03 PLC?
2: Can I use Rslogix 5000 to read the program through the Ethernet box?How I configure it?

Thanks

Shawn

You can use the serial cable “1756Cp3”. I think it is the same cable for SLC products.

I suggest using Ethernet for speed if your computer has network port.

To use Ethernet:
Set your computer setting as:
Setting > Control Panel > Network and Dial Up Connections >
Highlight “Internet Protocol (TCP/IP)”
Click Properties
Check the box “Use the Following Address”
Enter Unique IP Address eg 192.168.500. 001
Enter Subnet mask 255.255.255.000
(The first three address 192.168.500 must match your IP address of 1756-ENET module)

RS Linx setting
You can use “Remote Device Via Gateway” or “Ethernet Device” drivers.

In either case Add driver and Enter IP address of your Ethernet module eg 192.168.500.002

I hope this is just a typo in previous post:
192.168.500.001
IP address numbers can't be larger than 254

use 192.168.100.xxx or 192.168.1.xxx format

Also 1756-ENET module is discontinued, use 1756-ENBT.
1756-ENBT is 10/100 module with much better performance.

In order to use controlnet you must have at least one more node, taps and terminators.
RSnetworx for controlNet requierd to schedule the network.

Yes, 1747-CP3 and 1756-CP3 are same thing with different name and price tag. But.... you really should use this only for emergencies.
It's very very slow...

You can...

1747-CP3 and 1756-CP3 are electrically the same but physically different. The 1756 is a lower profile on the bent end to allow the door on a control logix proceessor to close. Regards Alan

Thanks. I really appreciate all of your help and it really helpful to me.

Thanks again.
