Master (FB)¶

FUNCTION_BLOCK Master

The FSoEBase Master function block implements the master side of the FSoE protocol and is responsible for establishing communication with an FSoE slave, parameterizing it and setting the FSoE watchdog time. With the call of the FB no execution is done, the flow control of the FSoE communication is executed by calling the functions of the FB.
