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 second. bError is used to indicate an error in communication with the drive. The type of the error can be read with iErrorID.

Inputs

  MP_Address             : USINT := 1;
  bStart                 : BOOL := TRUE;
  strDataKL6771          : DataKL6771;
  TMpolling              : TIME := t#10s;

END_VAR

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.
nOverrideControl_Write	E_MPBus_Override_6wayMPIV	The relative setpoint is ignored in override control mode. Overriding is disabled if the command is not repeated within 120 minutes.
rSetPoint_Write	LREAL	0…100 %.

Name	Type	Description
bBusy	BOOL	This bit is set for as long as the function block is active.
bError	BOOL	This output goes TRUE as soon as an error occurs. This error is described via the iErrorId variable.
iErrorId	MP_ERROR	This output outputs an error code in the event of an error. bError goes TRUE at the same time.
