Installation Guidelines
The following five mounting racks (CRs) are available for installing a central controller:
•
CR 700-0LA12 and CR 700-0LB11: for central controller 0
•
CR 700-1:
•
CR 700-2:
•
CR 700-3:
They differ in the number of slots and in configuration possibilities. The following pages describe
the four mounting rack types for central controllers and the modules that can be mounted on
them (connector pin assignment see Appendix C).
Possible Configurations on Mounting Rack CR 700-0 (6ES5 700-0LA12)
Use central mounting rack CR 700-0 to install small control systems. It has slots for a power supply
module (PS), a central processing unit (CPU), and up to four input/output modules (I/Os). Such a
configuration makes up a central controller 0. You can plug in an interface module (IM) to
connect expansion units (EUs), and the CP 530 communications processor to connect the SINEC-L1
local area network. You can also mount one intelligent input/output module. Figure 3-2 shows
the slots on CR 700-0 and the modules that can be plugged into each slot.
