Figure 403: Configuration example for the Manual and Auto single modes
The configuration example uses an mA signal to indicate the current tap position of
the local transformer. To take that position information to OLATCC, the measured
mA signal is first scaled with the X130 (RTD) function. The scaled value is then
converted to integer value with T_F32_INT8 function. That integer value is
connected to the TAP_POS input of the TPOSSLTC function. The tap position
value is automatically transferred from TPOSSLTC to OLATCC without a
configuration connection.
Configuration example for the Auto parallel (Master/Follower) mode
The configuration example for Master/Follower describes how the tap position
information is transferred from follower to master with the horizontal GOOSE
communication. The status information from circuit breakers and an extra logic can
be used to change the operation mode via inputs of the master and the follower
(Operation mode = "Input control").
