PM810 Energy Summary Usage and Energy Per Shift Usage Modbus Register read a value of 0
Issue
A user may want to read the Modbus Registers for Energy Summary Usage or Energy Per Shift Usage Values from a PM800 meter.
These registers are readable on the PM820, PM850 and Pm870, but not on the PM810.
The modbus register list has the Energy Summary Usage and Energy Per Shift Usage registers, Type- MOD 10 (16202 to 16346) marked as not supported for the PM810, but has the Energy Summary Usage and Energy Per Shift Usage registers, Type- Float (11864 to 11958) marked as supported.
This is an error on the modbus register list, because the Float registers pull the values form the MOD 10 registers. Thus Energy Summary Usage and Energy Per Shift Usage are not supported at all on the PM810.
That is, despite what is shown in the Modbus Register list, registers 11864 to 11958 are NOT supported on the PM810.
