MOVIGEAR^® SNI (Single Line Network Installation)^*

MOVIGEAR^® SNI – characteristics
Single Line Network Installation

• Individual control of MOVIGEAR^® with bidirectional communication
• Reduced number of variants and components
• Network topology
• Bus lines do not have to be routed in the field
• No risk of hidden faults in the bus cabling
• Reduced startup times
• Reduced overall project duration / reduced project costs

MOVIGEAR^® SNI –
Possible applications

• As drive for applications with high breakaway and starting torques
• As drive for conveyor systems that have to operated with variable speeds
• As drive for applications that require soft and/or defined start-up behavior
• As group drive for easier implementation of synchronous operation

Principle of communication

Data exchange between MOVIGEAR^® and PLC
• The SNI master is the interface between PLC and connected MOVIGEAR^® drive units
• The PLC receives status information of the MOVIGEAR^® drive units via SNI master. The SNI master also controls the MOVIGEAR^® drive units
• The SNI master distributes the data accordingly to the connected MOVIGEAR^® drive units
• The SNI master collects the status information of the connected MOVIGEAR^® drive units and makes it available to the PLC

Overview

Overview of the communication principle as well as handling of MOVIGEAR^® drive units (1 to 10) in the data buffer of the SNI master. Management, parameter setting and diagnostics of the drive units is carried out using the MOVIVISION^® configuration and diagnostics tool.
