MP_SR_actuator_Configuration

This function block is used to configure SR actuators. 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.

	Restrictions Call only if the corresponding “Process” function block is not executed.

Name	Type	Description
MP_Address	USINT	MP-Bus address of the slave.
bStart	BOOL	A positive edge starts the function block.
bRead_Write	BOOL	If FALSE then READ only; if TRUE then READ and WRITE.
strDataKL6771	DataKL6771	The data structure with which the KL6771() function block must be linked.
rMinPositionRel_Write	LREAL	Minimum operating range limit in % (0…100). Min must be <= Max − 20%.
rMidPositionRel_Write	LREAL	Adjustable value between Min and Max in % (0…100).
rMaxPositionRel_Write	LREAL	Maximum operating range limit in % (0…100). Max must be greater than or equal to Min plus 20%.
bMotionDirection_Write	BOOL	FALSE = normal; TRUE = reversed
stLocationString_Write	STRING	Location information, maximum 16 characters.

END_VAR

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.
rMinPositionRel	LREAL	Minimum operating range limit in % (0…100). Min must be <= Max − 20%.
rMidPositionRel	LREAL	Adjustable value between Min and Max in % (0…100).
rMaxPositionRel	LREAL	Maximum operating range limit in % (0…100). Max must be greater than or equal to Min plus 20%.
bMotionDirection	BOOL	FALSE = normal; TRUE = reversed
stLocationString	STRING	Location information. Maximum 16 characters.
stDeviceString	STRING	Belimo part number corresponding to the product model number.
