B&R’s latest addition to its Compact-S series is a compact controller with an integrated switch. With an integrated switch, it enables daisy-chain cabling between network stations.
At a width of only 37.5 mm including the power supply, the X20CP0420 is extremely compact. The controller achieves cycle times down to 4 ms and is equipped with 128 MB RAM and 256 MB internal flash memory. With Ethernet, USB and RS232, the controller offers plenty of communication options. An optional CAN bus interface is also available. With no fans or batteries, the compact controller is also maintenance free.
X20 I/O modules can be connected directly to the controller and line up seamlessly. The entire system saves a large amount of space in the control cabinet. Even with its narrow dimensions, the controller has a built-in power supply for itself and the connected I/O modules. There is no need for a separate power supply module.

Advanced Rotational Control
New software package suppresses rotational sway.
B&R has introduced a new function for crane control. Cranes that transport payloads suspended from sling systems can be particularly sensitive to rotation about the vertical axis. If left unchecked, this can lead to uncontrollable sustained oscillations. The new mapp Crane solution successfully damps this effect.
It is also possible to execute a controlled rotation, which can be helpful in cases where a payload needs to be positioned at a specific angle. With simultaneous control of both skew and sway, payloads can be brought to their destination with maximum speed and precision.
mapp Crane also offers automatic path correction, which adjusts for changes to the end position while the crane is in motion. This is an especially challenging task with regard to path planning, because the recalculations must account for the system’s oscillation dynamics in addition to its axis boundaries. With mapp Crane, this function can now be implemented with very little programming
