MP_EPIV_R6_V4_Configuration

This function block is used to configure the 6-way EPIV V4 DN 15…25 EP..R6 + BAC-HHx. For more information please visit www.belimo.com.

MP_Address is used to specify the MP-Bus device with which the function block is to communicate. bStart activates communication with the MP-Bus device. bBusy indicates that the function block is active. bError is used to indicate an error in communication with the actuator. The type of the error can be read with iErrorId.
