The Ekinex® EK-BO1-TP-RMA interface is a modular KNX S-mode device that allows bidirectional communication between the RDZ air handling units, equipped with control board with RS-485 Modbus communication port, and the KNX system (TP). Thanks to the interface, the functions performed by the air handling units can be controlled and monitored by KNX devices. The unit has an integrated KNX bus communication module and is realized for mounting on a 35 mm rail. Power is supplied via the KNX bus.

The interface represents a node on the KNX network
and performs the Master function on the Modbus network to which the control board of the air handling unit
is connected as the only Slave. The interface manages
a bidirectional data flow between Modbus RTU (Remote
Terminal Unit) and KNX. The Modbus registers are read
cyclically and their value can be sent as a communication
object on the KNX bus. The data update on the KNX network can take place cyclically and/or on variation event of
the data acquired by the Modbus network. The interface
acquires the value of KNX communication objects during
the exchange of telegrams on the bus. The acquired value is converted and written on the appropriate Modbus
register. The configuration is carried out by ETS by means of the corresponding application program.
