MP_EPIV_R6_V4_Process

This function block is suitable for 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. 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.

Name	Type	Description
MP_Address	USINT	MP-Bus address of the slave.
bStart	BOOL	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	DataKL6771	The data structure with which the KL6771() function block must be linked.
TMpolling	TIME	The time for which the function block should address the actuator. Default 10 s, minimum time 1 s.
rSetpoint	LREAL	Setpoint in % (0...100).
nCommand	E_MP_EV_V4_Command	Command for service and test functions of the actuator.
nOverrideControl	E_MPBus_Override_6wayMPIV_V4	Override the setpoint with defined values.
rSetpointSeq1_Write	LREAL	Setpoint for Sequence 1 in % (0…100).
rSetpointSeq2_Write	LREAL	Setpoint for Sequence 2 in % (0…100).
nDataRead	WORD	0xFFFF - Read all data Bit 0 – Read relative position Bit 1 – Read absolute position Bit 2 – Read value sensor 1 Bit 3 – Read analog setpoint Bit 4 – Read relative flow rate Bit 5 – Read absolute flow rate Bit 6 – Read glycol concentration Bit 7 – Read Temperature1 remote Bit 8 – Read Temperature2 integrated Bit 9 – Read temperature delta Bit 10 – Read relative power Bit 11 – Read absolute cooling power Bit 12 – Read absolute heating power Bit 13 - Total volume Bit 14 – Read cooling energy Bit 15 – Read heating energy
