FB_BA_SensorBinaryTLog

The FB_BA_SensorBinaryTLog function block logs a binary input value from an I/O bus terminal and outputs it as a Boolean process value.

The process value is logged by a Trend object.

Each template is available in 2 different configurations regarding the connection to the I/O process level, see I/O mapping. This documentation refers to the RAW variant.

	The initialization of the template takes place within the method FB_Init.
