Possible Configurations on Mounting Rack CR 700-2
Use central mounting rack CR 700-2 to install large control systems in 19-inch cabinets. It has slots
for a power supply module (PS), a central processing unit (CPU) and input/output modules. Such a
configuration makes up a central controller 2. You can plug in an interface module (IM) to
connect expansion units (EUs). You can also mount intelligent input/output modules and com-
munications processors (CPs). Figure 3-5 shows the slots on CR 700-2 and the modules that can be
plugged into each slot.

The DSI signal is not generated by the power supply
2 Digital modules of ES 902 design (S5-135/155U) can be plugged into slots 0 to 5
3 Block-type modules can be plugged into slots 0 to 6 and into slots 4, 5 and 6 only when using an IM 306; digital
modules of ES 902 design (S5-135/155U) can be plugged into slots 0 to 5
4 Do not remove the termination connector if neither IM 305 nor IM 306 interface module is plugged in
5 Interrupt processing is not possible in slot 6
6 Direct I/O access of the IP 252 with CPU 941, 942 or 943 is only possible in slot 0; CPU 944 only in slots 0, 1, 2; direct I/O
access is in general not possible when using the 3 A power supply module (HOLD and HOLDA signals are not
