Diagnostic Counters
Diagnostic counters can be used for debugging the Modbus system.
Counters will roll over from 65535 to 0. The counter values are stored to
permanent memory when power is disconnected.
Counters can be reset from the control panel by pressing the UP and DOWN
buttons simultaneously when in parameter set mode, or by setting them to zero
via the serial communication channel.
Note! Parameters 5206 - 5212 are displayed in hexadecimal format by the
control panel. The panel displays three decimal points to indicate a
hexadecimal number control panel.
