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 writing a zero from serial communication
channel 1.
Note! Parameters 5206 - 5212 are displayed in hexadecimal format by the control panel.
