Device configuration using
the example of a CM448R-
**26A1*
Ordered basic device (example) • Order code CM448R-**26A1*
• Functionality:
– 6 x Memosens (2 on BASE-E module + 2 on two extension
modules 2DS)
– PROFIBUS communication (module 485)
3 slots are still free in this example. More or fewer slots can be free in
other versions.
Extension options without additional
modules
None
Modification options without
additional modules
• Communication type changed by entering activation code. This
disables the communication type used previously!
– Modbus RS485 (71140889)
– Modbus TCP (71140890)
– EtherNet/IP (71219868)
• Retrofit to HART by removing module 485 and entering activation
code for HART (71128428)
Extension options by using extension
modules in free slots 5-7
Only the following is possible for the example above:
Module 2R (71125375) or 4R (71125376): 2 or 4 relays
If extending to eight measuring channels:
• Module 2DS (71135631): 2 Memosens inputs
• Use of the 2 current outputs in the basic module by entering
activation code (71140891)
Additional inputs or outputs, relays:
• Module 2AO (71135632): 2 current outputs
• Module AOR (71111053): 2 current outputs, 2 relays
• Module 2R (71125375) or 4R (71125376): 2 or 4 relays
• Module DIO (71135638): 2 digital inputs and 2 digital outputs

If you replace module 485 with ETH, you can operate up to 6
current outputs in addition to the ETH module's ethernet or
Modbus function. Only two current outputs are possible with
485.
Basic rule for extensions The sum of all current inputs and outputs may not exceed 8!
Restrictions if using CUS71D sensors
for interface measurement
The maximum number of Memosens inputs that can be used is
limited to 4! Here, every combination of CUS71D and other
Memosens sensors is then possible.
