.66.
This value can inform the state of digital input signal at fault.
The state of the current fault input terminal is decimal number. Display the state of all digital
input terminals at the latest fault, the sequence is:
BIT5 BIT4 BIT3 BIT2 BIT1 BIT0
RO3 RO2 RO1 HDO Y2 Y1
1 indicates corresponding output terminal is ON, while 0 indicates OFF.
Note: This value is displayed as decimal.
