Caution - Error Detected...
This previous thread reiterates most to all of what has been described so far in relation to which software version is required, how to inhibit non present I/O modules, setting the base type and also more info on error 0052h...
ML1400 Series B change to series A in RSLogix500
Have you noted in my info specifically what error 0052h means on a MicroLogix 1400? (What do you mean you didn't read it? Well now your going to have to!)

Micrologix 1400 Fault 0052H
Hi, I was trying to test an encoder, using the HSC, but I got this message as soon as I downloaded the code into the Micrologix 1400 Series B.
Code Hex: 0052H, "A module required for the user program is detected as missing or removed. This error is recoverable."

Most likely, your user program has an I/O module defined that is not physically connected to the PLC. That will cause the fault you describe...
The 0052h error described above, which you say was your first error, is specifically for an SLC processor. Error 0052h in a MicroLogix 1400 is quite different, but you already know this...
Why? Because later you described your second error...

...When I tried to get the PLC to run I got this message:
Major Error S:6 = 52h.
The base minimum series selected in the user program configuration was greater than the series on the actual base. Non-user error...
...where you say that it was also error "52h" but now with the correct description, as I know it. There is no error code, of any number, that I know of, for a MicroLogix, which is described as "A module required for the user program is detected as missing or removed". Again, this is specific to the SLC processors, to the best of my knowledge. There are certain error codes for the MicroLogix which are related to the I/O Configuration and modules being missing or incorrectly defined, but they are not error 0052h...

Where did you copy the text you provided us for error "52H" in your opening post? If you copy/pasted it from the knowledgeable or a certain manual, then perhaps you yourself have made an error and inadvertently looked up and passed on an incorrect description for the error you first received?
Why is all that so important? Well, besides potentially leading us astray in trying to resolve an error that was apparently incorrectly described, it would also mean you received the same error twice, and not two separate errors, as you have described.
If I'm incorrect here, and that error text did indeed appear for the MicroLogix for an error 52h, and then changed for the next error 52h, then I would be most interested in learning that fact.
As you now "appear" to be over all the error hurdles? The above is somewhat irrelivent other than to appease my Curious George nature.
One other thing not mentioned here, I think?, but also mentioned in that other thread I linked, is that to quickly resolve I/O Configuration mismatches, such as error 51h or error 52h for the base, you can use the Read I/O Config button on the I/O Configuration dialog, while you are offline. It will not work while online with the processor. However, while offline, the software must have a valid path to the processor in order to read in the physical I/O Config.
That "path" being your latest hurdle, it would seem?
In agreeance with ASF, your communications issue should have nothing to do with the fact that you are using RSLogix 500 v8.3, which does indeed support the MicroLogix 1400 Series B.
While we await details on the communications setup you are trying to use, I do have some duct tape here, in case yours has come loose?
Regards,
George
