Drives now have a PROFIsafe option
ABB has introduced a number of features and additional tools that offer the variable speed drives user more options when connecting drives to fieldbus networks.
One of the features is PROFIsafe, the safe version of the fieldbus system ProfiBus. This allows safety signals to be sent via fieldbus instead of using expensive hard wiring, reducing cost significantly. The addition of PROFIsafe to ABB drives brings commonality with the ABB AC500 PLC, allowing a complete safety system to be designed and built to enable PROFIsafe a special Ethernet module is required, the FENA-21.
This module has the added advantage that it is a two port device, allowing networks to be created with a daisy chain connection, removing the cost and complexity of Ethernet switches.
A remote monitoring module, the NETA-21, allows the drive to report via e-mail or text, generating tables and data about performance or faults.
