for the tap position are set in the RTD module. Since the values of the RTD module
outputs are floating point numbers, the float to integer (T_R_TO_I8) conversion is
needed before the tap position information can be fed to TPOSYLTC. When there is
a wired connection to the TAP_POS connector, the validated tap changer position is
presented in the TAP_POS output that is connected to other functions, for example,
OLATCC1. When there is no wired connection to the TAP_POS connector, the binary
inputs are expected to be used for the tap changer position information.
