Installation Guidelines
Possible Configurations on Mounting Rack CR 700-1
Use central mounting rack CR 700-1 to install small or medium-sized control systems. It has slots
for a power supply module (PS), a central processing unit (CPU), and up to seven input/output
modules (I/Os). Such a configuration makes up a central controller 1. Central controller 1 is up-
wardly compatible to 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 (IP, WF). Figure 3-4 shows
the slots on CR 700-1 and the modules that can be plugged into each slot.
