Information on configuring field devices on the H system

Redundant interface
DP devices which have access to a redundant interface are always configured and connected
redundantly (e.g. ET 200M, ET 200iSP).
DP devices which do not have access to a redundant interface are connected downstream of
the Y link. The number of field devices which can be configured downstream of the Y link is
restricted here by the I/O range of 244 bytes that applies in each case.
PA devices are always connected redundantly downstream of a DP/PA link.
