Liquiline CM442R/CM444R/CM448R
8 Endress+Hauser
Device configuration using
the example of a CM442R-
**M1A1F0*
A0025348
Ordered basic device (example) • Order code CM442R-**M1A1F0*
• Functionality: 1 x Memosens, 2 current outputs without HART
Extension options without additional
modules
• Second Memosens input (71114663)
• HART with activation code (71128428)
Extension options by using an
extension module in free slot 2
• Ethernet/PROFIBUS DP/Modbus with module 485 incl. activation
code for the desired communication protocol:
– PROFIBUS DP (71140888)
– Modbus RS485 (71140889)
– Modbus TCP (71140890)
– EtherNet/IP (71219868)
– Only Ethernet without fieldbus (71135634)
If fieldbus communication is subsequently required, an activation
code is needed for this.
• Alternative for Ethernet or Modbus TCP: module ETH
If you retrofit module 485, any existing current outputs are
disabled! Alternative: ETH (Ethernet, Modbus TCP only).
Additional inputs or outputs, relays:
– Module 2AI (71135639): 2 current inputs
– 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
Basic rule for extensions The sum of all current inputs and outputs may not exceed 8!
Restrictions if using CUS71D sensors
for interface measurement
Only one CUS71D can be connected. The second Memosens input
may not be used.
