act_MaxVol: maximum set volume flow rate in %.
act_MinVol: minimum set volume flow rate in %.
bErr_ActHunt: actuator error, "Regulating oscillation": the actuator is swinging backwards and forwards.
bErr_MecTrv: actuator error, "Positioning angle exceeded": the actuator has passed more than 10° beyond
the adaptation position.
bErr_MecOvld: actuator error, "Overload": the set position could not be reached.
bPositionSetByHand: the position of the actuator was changed by hand.
bSynchronizationActive: the actuator synchronizes.
6.2.8 MP_EPIV_R6
This function block is used to control a control ball valve of series EP..R-R6+BAC.
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 s. bError is used to indicate an error in communication with the actuator. The
type of the error can be read with iErrorId .

MP_Address: MP-Bus address of the slave.
bStart: a positive edge starts the function block. If this remains continuously TRUE, the function block will be
activated cyclically with a period specified by the time in TMPolling .
strDataKL6771: the data structure with which the KL6771 [
}
25] function block must be linked (see
DataKL6771 [
}
72] ).
TMpolling: the time for which the function block should address the actuator. Default 10 s, minimum time
1 s.
nOverrideControl_Write: the relative setpoint is ignored in override control mode (see
E_MPBus_Override_6wayMPIV [ } 70] ). Overriding is disabled if the command is not repeated within
120 minutes.
rSetPoint_Write: 0...100 %.
