MP_EnergyValveV4_2_Process

This function block is suitable for Energy Valve actuators EV..R2+.. with firmware 4.2.0 or higher. 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. If bStart remains TRUE, the device is addressed cyclically with a period specified by the time in TMPolling. The time should be set longer than 1 second. bError is used to indicate an error in communication with the actuator. The type of the error can be read with iErrorId.
