- In order to encapsulate knowledge into function blocks, have more configurability of devices and features and apply models as a network of function blocks, the function block architecture of IEC 61499 has bee developed. IEC 61499 provides a new degree of flexibility in managing embedded control and information processing systems. IEC 61499 can also be used in a network of function blocks wherein an application is distributed across different computing devices. IEC 61499 provides a mechanism for creating new device types as a set of resource types and function block libraries and uses an Open XML-based device management protocol, which in turn enables configurability of compliant devices by compliant software tools. As such, IEC 61499 is a far better solution that existing PLC systems, not to mention the fact that it allows creation and deletion of resources which are containers for applications. IEC 61499 function blocks have enabled features such as reconfigurability, PnP, independence of target execution platforms and independence of control strategy.
