This bean (in cooperation with similar device as SynchroSlave) implements a serial synchronous master-slave communication. Only two devices can communicate - one of them is a MASTER and the other one is a SLAVE.

The difference between the master and slave is that the master generates the clock signal while the slave receives it. Consequently, if the master has no data to send to slave and needs to receive data from the slave, it still has to transmit a character. For example a reserved character called "empty character" that may be ignored by slave (see properties Empty character and Ignore empty char. ).
This bean allows to set an empty character to cut such a character after the reception of it.

That also applies vice versa - if the slave has no data, it sends an empty character to the master.

The type of the user type BeanName_TComData is a byte.

This bean belongs to the category: CPU Internal Peripherals-Communication
