Communication implements data reading from devices that support the M-Bus protocol by the Rev. 4.8 specification. Communication was tested with MULTICAL® III, MULTICAL® 5 measuring devices by KARMSTRUP Company, CALSTREEM EEM-C measuring device by Danfoss Company, and PolluTherm Pt500 by Sensus.
The communication was also verified against the water flow meter Sensus MeiStream 150 with communication module HRI-Mei using an EthMBus-5 converter manufactured by JC-e (it was necessary to configure a converter to TCP mode and use a TCP/IP-TCP line category).

The attached ZIP contains the configuration of the line, station, and I/O tags with the M-Bus protocol that communicate with the Sensus MeiStream 150 flowmeter with the HRI-Mei communication module and using an EthMBus-5 converter manufactured by JC-e in UDP mode (the converter has an IP address of 192.168.1.1 in the line configuration). | View file |
