Time(BI#Time)
Each change (rising or falling edge) detected in the status of a binary 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 frequency range of a binary input parameterized to operate as a pulse counter is
0...100 Hz. If a binary input is changed into a pulse counter, the attribute BI# is frozen at
the value valid at the moment of the change.
The example below shows how the attributes of the binary input 1 (PS1_4_BI1 on PS1
module) of the machine terminal REM 543 are named for the configuration:
PS1_4_BI1IV; binary input invalidity
PS1_4_BI1; binary input value
PS1_4_BI1Time; time tag
PS1_4_BT1Count; counter value
4.1.7.
Binary outputs
The outputs of the REM 543 machine terminal are categorized as follows:
•
HSPO Power output, double-pole contact, preferred for tripping purposes and for
circuit breaker and disconnector control
•
SO
Signal output, either NO (Normally Open) or NO/NC (Normally Open/Nor-
mally Closed) contact.
*) Trip Circuit Supervision function included.
