Allen Braddle SLC500 SLC5/04 help Req

im using Slc5/04 one of its 8 channel analog output module 1746-NO8I got defective if i replace it with new one do i have to re-program or re-configure it
or directly plug and play?

If the part numbers match then yes. Be sure to power down the rack first though.

Im in searching this 08 channel analog output card 1746-NO8I but not available in pakistan any alternate? (all 08 channel in use)

No. Have you spoken to your Rockwell distributor? The cards are still available.

contact with toufiq sb ACT in this regard

Who they are? ACT? any contact detail?

PLC SLC5/04 is runing with 1746-NO8I but this module is got defective How can i Use 2 module of 1746-NO4I instead of 1746-NO8I?
kindly Help

Well that would require reprogramming half your analog inputs

1. Get a fresh copy of the program (while online, save and upload all data).
2. Go offline.
3. Save as...with a new name
4. Go to the I/O configuration and make the required changes to match the new intended configuration.
5. Suppose for the sake of an example that the NO8I is replaced with NO4I in slot 5 and a new NO4I is installed in slot 6 where no card existed before:
Search and Replace the following addresses in the offline file:
O:5.4 with O:6.0
O:5.5 with O:6.1
O:5.6 with O:6.2
O:5.7 with O:6.3
6. For this step, I would need to reference the manuals to give exact details, but you may or may not need to modify the logic to ensure the configuration data for the cards are correct. Some of hte SLC analog cards require that you have the proper values in the extended data configuration words in order to set up the ranges properly. I believe RSLogix500 may be able to do some or all of this for you, but you will need to review what is going on with those data points in the old program.
7. Power down the SLC
8. Switch the keyswitch to program mode.
9. Install the new cards and rewire the analog signals.
10. Double check your wiring and make sure that if external power is required, you have supplied it (I don't know off the top of my head if that is optional or required).
11. Check the wiring again. Better yet, have a competent partner check your work.
12. Power up the SLC with the keyswitch in program mode.
13. Download the new program.
14. Put the keyswitch back in run mode and then to remote run mode (if that is where you want it during normal operation).
15. Verify that everything is working as intended.

I like to switch to program mode before making I/O changes so that the PLC does not fault. I had at least one situation where I caused a fault by powering up with the wrong I/O configuration and the SLC freaked out and would not let me get online to straighten things out. I found that not faulting the SLC may save a little headache at least every now and then, but it is not a show stopper if you leave it in RUN mode and then have to deal with the extra steps of clearing the fault before downloading the corrected file.

Dear okipc,
Thanks.we learn something new which we do not know.
Regards.

i have RSlogix 5000 but it not shows my CPU Number SLC5/04 1747

RSLogix 500 is the software that programs SLC-500 and MicroLogix controllers.

RSLogix 5000, which in its modern form is called Studio 5000 Logix Designer, is the software for the ControlLogix and CompactLogix controllers.

To work with the program for an SLC-5/04 controller, you need RSLogix 500.
