Wirelessly Controlled Cranes
Wireless cranes offer the freedom and cost-savings associated with trailing cables, while still providing the critical safety support needed utilizing a PROFIsafe network. Operators can manage crane functionality from a centralized control station, or from any point on the plant floor using a mobile HMI. Both options offer increased flexibility and efficiency.
Properly positioned access points define the accessible work area which can be as small as one access point or as large as a network of access points with proper planning.
Data is transferred between the control system and cranes via Industrial Point Coordination Function (IPCF) or Industrial Point Coordination Function – Management Channel (IPCF MC). Standard data such as transport orders, status messages and failsafe communication can run in parallel on the same connection. For this purpose, each crane is equipped with an Industrial Ethernet client module that is connected to the crane controller.
Because there is no wired connection, communication between the control system and the cranes, and between the cranes themselves and their environment, must run on a reliable and robust wireless network.
