To reduce cabling effort, Moba developed a controller that contains an integrated terminal strip on top. OEMs are now able to wire their machines directly to the top of the controller.
There is one challenge in installing a mobile controller into a cabinet: Usually, the controller and the terminal strip are placed right next to each other, wired via the controller’s plug. This causes quite some cable work. However, for convenience reasons and most importantly for increased service-friendliness, there must be another solution. Moba thus has developed a controller that contains an integrated terminal strip on top. The necessary supplies are available at the inputs and outputs. OEMs are now able to wire their machines directly to the top of the controller. If a controller needs to be maintained or changed, one can disconnect the plugs and unwire the controller within minutes.
Ruthmann, manufacturer of truck-mounted working platforms, uses the Modular Control Panel MCP for their Steiger-series and models called ‘Cockpit’. The integrated cabinet contains the mentioned controllers with a time-efficiently removable plug and clamp combination on top. The MCP allows combinations of components, such as keypad, joystick and display modules. Furthermore, two gateway controllers are integrated to get a redundancy of the I/O’s if needed. In the case of two controllers, the left controller is key element and operates as a gateway of the internal Moba bus to the external machine bus.
Also, the left controller administers all Moba components through CANopen, CiA 301 Version 4.02. Both controllers are integrated into the machine bus and communicate via the CANopen protocol. This facilitates an integration of the control panel into the machine of any manufacturer. Beside its function as the administrator of several Moba components, the controller can be used as a plain I/O device. It has 16 digital and 8 analog inputs. For the user, it is possible to individually configure each digital input with the CANopen object directory.
The described controller is suitable for a space-optimized cabinet, which does not allow too much cable work and thus requires special terminal strips. Furthermore, by saving considerable amounts of clamps and cables, the associated wiring work is omitted, thereby reducing wiring faults to a minimum. The possibility of a time-efficient exchange is an extra advantage for the machine manufacturer’s service team, saving considerable resources.
