S5-95F
Expansion of Basic System with External 110s
5.2
Multi-Tier Expansion
If it is not possible to have all of the modules located on one tier, then you can expand the con-
figuration up to four tiers. You may use a maximum of 8 bus units
for each subunit. It does not
matter how many bus units are mounted on a tier.
You need one interface module per tier to
connect the tiers one to the other.
Install an interface module as you would install a bus unit. You must connect each interface module
to the last bus unit via the flat ribbon cable.
Use the
IM
315 interface module for two-tier configurations.
The
IM
315 consists of two modules
permanently connected via a 0.5-m (20-in.) cable.
Use the IM 316 interface modules for multi-tier configurations.
Use the 712-8 connecting cable to
connect the
IM
316 interface modules (Order No. 6ES5 712-8...).
The standard mounting rails must have a common reference potential if they are mounted in
different cabinets.

Safety Note
For reasons of EMC you must cover unused sub D locations on the
IM
316 interface
module with an empty sub D connector (6
ES5-750-2AA21
).
