Remote IO

[Guest trn_psycho]

Can anyone explain remote IO addresses to me? I have a panelbuilder 1400e application that calls addresses like B04 63/07. But when I open up the rslogix program (that the panelview is attached to), there isn't a b4 or b04 datafile...

Is the Panelview and PLC networked with another PLC? What PLC are you attached to?

As for Remote IO - assuming you are connected to an SLC look at the following links: http://literature.rockwellautomation.com/i...um013_-en-p.pdf http://literature.rockwellautomation.com/i...um009_-en-p.pdf http://www.ab.com

It's attached to a SLC 505. I've figured out where the addresses point to, but I can't find what tells the panelview (or is it the processor) what to map the address to. For example: In my application, B02 01/0-01/15 points to datafile N222:01. What makes the B02 correlate to N222?

I assume your SLC rack has a Scanner Module which is communicationg to your Panelview through Remote IO. In which case there is some COP blocks resident in the PLC, this sets up the communication for the block transfer information in the PV1400 software. The PLC is recieving the data file n222:01 at a certain length, appears to be 16 words from the Panelview using COP instruction in the SLC and RIO block transfer 2 which is configured in PV1400 under RIO Block Transfer Files. I would suggest looking closely at the Links user Guest_silva.foxx posted, looking into the M and G data and how it is configured in the SLC RIO is sometimes very difficult to backtrace if it was not documented thoroughly by the programmer.

You might also look for block transfer instructions (BTW, BTR) because the newer SLC cpu's supprts them. In the PV1400e app, look for the block transfer configuration and you'll see that the B04, B02 are actually aliases for the block transfer configuration to/from the PLC. The block transfer should show the Rack, Group and Slot number similiar to the ones you would see in the PLC BTW/BTR instructions. From this you should be able to correlate which PV block transfer go to what PLC block transfer and thus the address.
