DECS-200N Register Tables
Three categories of DECS-200N information can be accessed through the IDP-800 using the Modbus
communication protocol: C2 (metering), C5 (operating modes), and C6 (setpoints).
DECS-200N Metering Information Category C2
Category C2 holding register assignments and descriptions are listed in Table 6.
