Power meter PM710MG and CitectSCADA

4 posts in this topic

Hi all mrplc members, I use CitectSCADA to monitor PowerLogic PM710MG. Connnection's good (Modbus RTU). But I can't read the Real Energy Total register (Add 1000). With float register: Add(citect) = 40000 + [Add(pm710) - 2] Ex: Current, 3P Average; Add(pm710) = 1018, --> Add(citect) = 41016. Citect gets the value exactly, but it can't read the Real Energy Total ( Add: 40998) !!!! Anyone can help me??? Thanks Edited by Nguyen Hong Hao

Suggests to me you may be reading a single word ans I would think total energy would probably be a double word.

PM710 does not have float registers, check the PM710 manual, its all in there
