| Introduction | |||
|
A Sercos object manages an individual SERCOS master. The SERCOS (Serial Real-Time Communication System) protocol was designed specifically for the motion control industry. The protocol uses a ring topology which allows communication to occur at specific assigned times within a predetermined cycle. Thus, SERCOS is deterministic allowing the Master (control unit) to synchronize command and feedback values to and from all of the Slaves (drives). The MPI supports the use of SERCOS fiberoptic technology. The XMP-SERCOS-CPCI supports up to 3 SERCOS rings with support for up to 24 drives, in a 2-slot configuration in a CompactPCI form-factor. The MPI includes 4 SERCOS object types: SERCOS, NODE, IDN, and IDNLIST. Utility programs for initializing a ring and reading or writing IDNs are also provided with the software distribution. Only a limited number of SERCOS drive manufacturers are supported in the MPI. For a list of supported drives, click here. Contact MEI for more information about supported SERCOS drives. |
