Siemens SIMATIC S5-115F - Interconnecting the Two Subunits

S5-115F Manual Installation Guidelines
3.2.4 Interconnecting the Two Subunits
The two subunits are interconnected via an IM 304 / IM 324 parallel link. The IM 304 interface
module can be plugged into either subunit A or subunit B.
The IM 304 and IM 324 modules are connected to each other with the 721 connecting cable over a
maximum distance of 10 m (33 ft.). The cable is connected to the lower of the two interface ports.
Please use the switch and jumper settings shown in Figures 3-19 and 3-20 for establishing the
parallel link between the two subunits.
