System Status Registers
The HES has a wealth of diagnostic data to help identify any HES or field device issues. The
status registers are organized in a hierarchy, with the higher levels summarizing the contents of
the lower levels (see table 6.2). These registers are displayed on the ‘System Status Registers’
webpage and can also be found in the MODBUS registers.
