TK9_DI_COMPACT and TK9_DI_FULL (Digital Inputs)

The two data structures for digital input channels (TK9_DI_COMPACT and

TK9_DI_FULL) provide the elements detailed in the tables.

Table 10: TK9_DI_COMPACT Structure for Digital Inputs

Identifier Type Description Remarks

<tagname>.DI BOOL Input state TRUE: input voltage above threshold T6

FALSE: input voltage below threshold T5

<tagname>.LF BOOL Line fault TRUE: input voltage above threshold T8;

between T5 and T4; or below T1

FALSE: input voltage between thresholds T2

and T3; or between T6 and T7

<tagname>.DIS BOOL Discrepancy TRUE: there is a discrepancy in voltage greater

than 20% between the channels of two or

three modules in a redundant configuration (†)

Table 11: TK9_DI_FULL Structure for Digital Inputs

Identifier Type Description Remarks

<tagname>.DI BOOL Input state TRUE: input voltage above threshold T6

FALSE: input voltage below threshold T5

<tagname>.LF BOOL Line fault TRUE: input voltage above threshold T8;

between T5 and T4; or below T1

FALSE: input voltage between thresholds T2

and T3; or between T6 and T7

<tagname>.DIS BOOL Discrepancy TRUE: there is a discrepancy in voltage greater

than 8% (of 24V) between the channels of two

or three modules in a redundant configuration

(†)

<tagname>.CF BOOL Channel fault TRUE: module diagnostics detect a fault in the

channel electronics or firmware (state = 7)

<tagname>.V UINT Voltage Reports the channel voltage in units of

millivolts and with an accuracy of ± 500mV

(††)

<tagname>.STA USINT State Reports a state value for the channel:

1 = open circuit

2 = de-energized

3 = indeterminate

4 = energized

5 = short-circuit

6 = over voltage

7 = faulted
