Siemens Profibus IM153 differences?

Hi guys,

Currently we have a project & Siemens supplied us a pair of Profibus module with part number 153-2BA02-0XB0, but the one using at customer site is 153-2AA02-0XB0.

Does anyone knows what is the differences? I tried to look from the web, but no luck. Thank you.

Hello ckchew666;

Here is the closest I could find:



It comes from manual ET200M_e-6ES7153-2BA81-0XB0.pdf, on Siemens website.
Hope this helps,
Daniel Chartier
