Value (BI#)
Depending on the status of the digital input, the digital input value is TRUE (1) or
FALSE (0). The BI# value changes on the rising or falling edge of the input. To
prevent undesired status changes of the digital input due to switch debouncing, etc.,
the change of the attribute value is delayed by the filter time.
The counter attribute of a digital input is not updated when the input is programmed
as a normal digital input.
Time (BI#Time)
Each change (rising or falling edge) detected in the status of a digital input is time-
tagged at an accuracy of ±1 ms. The time tag represents the moment (time) of the
latest input change of the value attribute. The time is not recorded until the filtering
time of the status change has elapsed, which means that the filtering time does not
affect the time tag value.
Count (BI#Count)
The count attribute indicates the number of positive input transitions of a filtered
input.
5.1.8. Digital outputs
The outputs of the machine terminal are categorized as follows:
The events and parameters of I/O cards are included in the event and parameter lists
on the CD-ROM Technical Descriptions of Functions (see “Related documents” on
page 10).
For information about terminal connections for the outputs, refer to terminal
diagrams (beginning on page 86), where all the outputs are included with relay
connector terminals.
For technical data of the outputs, see Table 5.2.1-6 on page 82.
HSPO High-speed power output, double-pole contact, preferred for tripping
purposes and for circuit breaker and disconnector control
PO Power output, either single-pole or double-pole contact, preferred for
circuit breaker and disconnector control
SO Signal output, either NO (Normally Open) or NO/NC (Normally Open/
Normally Closed) contact
