3.3 CIM 260 3G/4G cellular Modbus
You can establish remote communication via CIM/CIU 260 by
using one of the following options:
• Modbus RTU protocol via a cellular call-up connection
• Modbus TCP protocol via a cellular data connection
• SMS commands from a mobile phone.

installed inside the CU 352 controller

Fig. 7 Example of a CIM 260 solution for Hydro Multi-E
model H and later. Pumps connected via built-in radio
communication (Grundfos Glowpan)
The example for Multi-E model H and later is identical for TPED
model H and later and MAGNA3-D. In all cases, mount the CIM
module in the master pump placed to the left.
For the purpose of redundancy, you can mount a second CIM
module in pump 2 for TPED and Multi-E (not MAGNA3-D). In that
case, all writings from the Modbus master must be sent to both
CIM modules.
