Modes

The target mode for a DI function block can be set from three block modes: O/S, Auto,
and Man.

PV Value (PV_D)

A limit switch signal is transferred from the transducer block via a channel. Normally, the
Transducer Value and Transducer Status values in SIMULATE_D are copied to
FIELD_VAL_D, indicating the on/off status of the corresponding limit switch. If
SIMULATE_D is set to Enable, the Simulate Value and Simulate Status values in
SIMULATE_D are copied to FIELD_VAL_D.
SIMULATE_D contains the following data:
Simulate Status
Simulate Value
Transducer Status
Transducer Value
Enable/Disable
The value of FIELD_VAL_D is copied to the process value PV_D. At this time, if the Invert
option (bit 0) is specified as true, the on/off status is inverted (Table 41).

Filtering

Transfer of a change in the value of FIELD_VAL_D to the value of PV_D can be delayed
for a desired time period set in the parameter PV_FTIME (in seconds).

Output

The value of the output OUT_D is generated based on the value of PV_D.
