Fieldbus Communication Note: To create a CIU xxx solution, you need to order a CIU 900 + the required CIM xxx interface and mount the CIM xxx interface into CIU 900. Note: E-pumps are CRE/CRNE/CRIE, MTRE, CME, TPE2/TPE3, NBE/NKE. Note: For TPED and Multi-E a second CIM module can optionally be mounted in pump no. 2 for network redundancy. A second CIM module can optionally be mounted in pump no. 2 for redundancy MAGNA3-D model D requires 1x CIM in master head, MAGNA3-D models A-C require a CIM in each head (for LONWorks 2x CIM 100) CIM 290-MA LPWAN GIC requires an external 4G/3G antenna.
