Description
1.1
Application
1.4
The IM 300-5LAll and IM 300-5LBll expansion rack interface modules are used for connecting expansion racks ER 701-1 of the S5-115U system to the following central controllers in centralized configurations: S5-11OS/B S5-130K, W/B S5-135U S5-150K, S and U

Up to three ER 701-1 expansion racks can be hooked up to one central controller. The IM 300-5LAll and IM 300-5LBll interface modules differ only as to their mounting width.
1.2
Principle of operation
Construction
o Expansion racks can be mounted above, under or beside the central controller'. o The cable used must not exceed 2.5 m in length. o Because of the voltage drop in the connecting cable, the expansion rack with the highest current consumption should be located as near as possible to the central controller. o The permissible loading of the power supply in the central controller must not be exceeded. o Terminators need not be plugged in to any unused connectors on the interface modules. o The central controller and expansion racks must be connected to the PE conductor to prevent noise soup1 ing. (Conductor crosssection 2 6 mn ).
The IM 300-5 powers the expansion racks with +5 V and transmits the bus signals for driving digital and analog input/output modules from the central controller to the expansion rack. The signals are transmi tted asymmetrically with the 705 shielded connecting cable.

Addressing with the 11OSIB programmable controller
The S5-11OS/B p r o g r a m a b l e c o n t r o l l e r uses t h e i n p u t / o u t p u t addresses
These addresses may no l o n g e r be used i f t h e I M 300-5 i s plugged i n t o t h e expansion r a c k . The f o l l o w i n g addresses are a v a i l a b l e f o r d i g i t a l modules:
I n t h e case o f t h e S5-11OS/B, these addresses a r e n o t taken i n t o account when t r a n s f e r r i n g t h e process immage, i . e . t h e process image must be t r a n s f e r r e d b y t h e user program.

However, o n l y i n p u t l o u t p u t modules t h a t are a c t u a l l y plugged i n may be r e f e r enced.
