Is it possible to use TU847 unit for single PROFIBUS system?
I have TU847 termination unit, and I want to use this unit with single PROFIBUS CI840A module. I would like to ask that is this unit works with single PROFIBUS module or is it just for redundant system and I should by another termination unit?
Tu847 is a mtu for red. Profibus dp v1 interface with non-red io modules if u want to use red io modules then u should use tu846 as mtu.
Since you want to use single profibus interface then run your system with non-red ci854 and connect only A line only still you can able to run the process.
Due to this you won't get any line or module red so always try to use red ci854 with red ci840 to achieve d same.
