My experience with the RB Module in a remote rack (done by others) was "don't do that!"
It worked fine for 12 years until after a plant shutdown it decided that nah, we're just not going to let those integers block transfer across from this module anymore. The RB module was reading barcodes up until that day and controlling a tire sorting line. We worked on that mess for two days while the operators manhandled the tires since the sorter no longer worked. New chassis, new blue hose, new PLC-5, different adapter module, I think we got partial success by changing the hardware revision level of the chassis. We finally got a true A/B guru on the phone who said that RB module must be in the main chassis with the PLC-5. We had to rewire two slots of digital I/O and edit the program in order to move the RB module (all three racks were in the same panel, so not too terrible) and after doing that and adjusting the BTR/BTW addressing to match, we got it to work again.
This is just my only anecdote about the RB module and it is an old memory from around 2001, so keep that in mind.
