Issue
Customers want to know the mapping of the QoS Diagnostics Data on CPUs and BMENOC0301/11 communication modules in M580 systems.
Product Line
Ecostruxure Control Expert, Unity Pro, M580, BMENOC0301, BMENOC0311
Environment
Control Expert v14.1, Windows 10 version 1902 (OS Build 18362.30), BMEP586040 v3.10, BMENOC0301 v2.17
Resolution
QoS Diagnostic data of 11 words, are availalble on CPUs and BMENOC0301/11 communication modules using Modbus function code 3 with the unit ID set to 100, offset Modbus Address 1275 and below is the MODBUS Register Mapping:
