Another possibility is two identical components, provided they have different
node addresses.
For setting the addresses (also see corresponding component section):
– HHU: Via DIP switch or display (see "Handheld unit" section),
– For HT 6, by adapting the address before commissioning (refer to
Operating Components "Handheld Terminal HT 6").
No bus terminating resistors may be inserted at the distributor boxes of an
HHU or HT 6 (refer to the note on item 2.)
If required, more than one HHU/HT 6 can be connected to a bus segment
using intermediate repeaters.
may not be exceeded:
MPI (187.5 kbaud): Max. total cable length is 1000 m
OPI (1.5 Mbaud): Max. total cable length is 200 m.
