Via coded binary (Binary), binary coded decimal (BCD) signals or Gray coded binary signals
SEMOD159170-24 v3
The Tap changer control and supervision, (TCMYLTC or TCLYLTC ,84) decodes binary data from up
to six binary inputs to an integer value. The input pattern may be decoded either as BIN, BCD or
GRAY format depending on the setting of the parameter
CodeType
.
It is also possible to use even parity check of the input binary signal. Whether the parity check shall
be used or not is set with the setting parameter
UseParity
.
The input BIERR on (TCMYLTC or TCLYLTC , 84) can be used as supervisory input for indication of
any external error ( Binary Input Module) in the system for reading of tap changer position.
Likewise, the input OUTERR can be used as a supervisory of the Binary Input Module.
The truth table (see table
510) shows the conversion for Binary, Binary Coded Decimal, and Gray
coded signals.
