GENIbus

The TwinCAT PLC library TcGENIbus.Lib contains communication function blocks for the GENIbus master/slave communication from the TwinCAT PLC. GENIbus (Grundfos Electronic Network Intercommunications bus) is a protocol specially developed by the Grundfos company for the exchange of data with its devices. Several Grundfos devices can be connected via GENIbus to form a network and to be integrated into an automation system.

GENIbus is based on the RS485 hardware interface. Data exchange takes place at 9600 baud. In most cases a GENIbus network consists of a master and up to 200 slaves.
