SLC 500 CPU Fault

[tranebwc]

hello
at work we have a machine controlled with an SLC 500 fixed, model 1747-l30c at fault, i plan to migrate to a micrologix controller.
I'm trying to connect with the UIC, but i cannot seem to find it on RsLinx, i've worked with micrologix, controllogix and 5/03s & 5/04s, but i can't seem to configure this controller to appear on RsLinx.
Can someone point me in the right direction?
Will i need to use the PIC?

Any help will be much appreciated

Hello Mickey
that is the configuration that i've used to connect to the 5/03 PLCs, but it is not working on this SLC 500.

On the UIC, the USB and OK led status are on, but the DH485 led is not blinking.

Do you have a offline copy of the program so that you can see what the com port speed is, it is most likely set to 9600 and the 1747-UIC defaults to 19200.
To get the software (called gateway) to be able to use the 1747-UIC on 9600 go to the Rockwell Knowledge base https://rockwellautomation.custhelp.com/app/answers/answer_view/a_id/493842/loc/en_US#__highlight

You will need an account to log in, but this TechNote is available to everyone.

Helo alan_505
i changed the baud rate on the UIC with the gateway software, still no luck, i cannot see the slc on Rslinx. Only the USB and OK leds are turned on on the UIC.
i tested the UIC on a 5/03 and i can see it on Rslinx.
this SLC500 can't seem to communicate.

Sorry I cant help anymore, maybe you need to get someone in who has the old 1747-PIC and a suitable laptop to be able to run it.

Interesting old post..

I dug out a bunch of old SLC-500 gear tonight to figure this out for myself.

The 1747-UIC evidently only works with Fixed I/O SLC-500 controllers (the old 1747-L20, -L30, -L40) when they are on active DH485 networks.

One modern way to provide the extra DH485 node when you want to go online with a fixed SLC is to use a 1761-NET-AIC and a small MicroLogix 1000 set for default protocol = DH485. You can connect the MicroLogix and the 1747-UIC to the two RS-232 ports on the 1761-NET-AIC, then connect the DH485 trunk port of the 1761-NET-AIC to the DH485 network port of the Fixed SLC-500 controller.

Systems that have Fixed SLC-500 controllers connected to PanelViews, DTAMs, or other SLC controllers using 1747-AIC isolators will work when you plug the 1747-UIC into the 1747-AIC's "Peripheral" port.

Maybe Ken will check in on this one or someone else.

The subtle difference is that the fixed SLC and (I believe) the 5/01 and 5/02 cannot "initiate the token" and rely on the PIC or another network device to do so. This is an issue for certain 3rd party DH485 drivers as well.
