Using 1747-dps? for 2 Operator Panels

I want to take a SLC 5/03 that is already connected to a Display (using RJ485 port) and 2nd port is connected to a modem. I want to add a 1747-dps1 or 2. The added port would give me an open port for trending and historical data saving. So, does the added port(s) of the 1747-dps? give me the same options as the RS232 - DF1 port of the 5/03? Is the speed the same? Any other drawbacks from this?

Thanks

Is there a different / better route to take?

Just another option....

I have not done it but I think you could add a 1747-AIC and set up a 485 network, you could have your display and pull the data off the same connection

Here is the manual http://literature.rockwellautomation.com/idc/groups/literature/documents/in/1747-in062_-mu-p.pdf

I agree 3 floor said idea ,if you still want to the add 1747-dps ,I advise you add the 1747-dps2.because the 1747-dps2 have 9 pin male D shell.
