MOVIGEAR^® SNI System Components

SNI Controller
The SNI controller is intended for decentralized installation in the field. It enables control of up to ten MOVIGEAR^® units. The controller transfers the control information to the SNI controller by means of Ethernet signals. The SNI controller is the interface between PLC and connected MOVIGEAR^® drive units.

The SNI controller controls the MOVIGEAR® drive units. In return, the PLC receives the status information of the MOVIGEAR® drive units via the SNI controller. The SNI controller distributes the data from the data buffer to the connected MOVIGEAR® drive units accordingly. It collects the status information from the connected MOVIGEAR® drive units and makes it available for the higher-level PLC. Administration, parameter setting and diagnostics of the drive units is performed by using the MOVIVISION® parameter setting and diagnostics tool.

MOVIGEAR^® SNI
In the MOVIGEAR^® SNI, the control information received from the SNI controller is evaluated and the commands are translated into a corresponding movement. The status (e.g. ready for operation, velocity, position, unit utilization, etc.) is transferred to the higher-level SNI controller as status information. The address under which the MOVIGEAR^® unit is known to the SNI controller is set in the unit via DIP switch. If a unit is replaced, the identical address is set in the new one, so that the corresponding parameter set can be automatically uploaded from the MOVIVISION^® data base.

MOVIGEAR® SNI is characterized in particular by its novel installation and communication concept: Individual control of each MOVIGEAR® Reduction in the number of components Bus lines do not have to be routed in the field No risk of hidden faults in the bus cabling Reduced startup times Shorter project runtimes / lower project costs
