FB_KL6581

This function block takes care of communication with the KL6581 EnOcean® Bus Terminal. This function block is used to configure the KL6581 and start data exchange with the EnOcean® network.

	Restrictions Only one call per instance Call must be made once per PLC cycle Instance must be called in the same PLC task as the send and receive blocks assigned to it Maximum 64 instances per PLC project allowed

Inputs
