6.2.11 MP_EV_Parameter
This function block is used for parameterization of valves.
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 block is active. bError is used to
indicate an error in communication with the drive. The type of the error can be read with iErrorId .
VAR_INPUT
MP_Address : USINT := 1;
bStart : BOOL;
strDataKL6771 : DataKL6771;
dwPassword : DWORD;
nControlMode : E_MPBus_ControlMode := MPBus_ControlMode_Disable;
nDetaTLimitation : E_MPBus_DeltaTLimitation := MPBus_DeltaTLimitation_Disable;
rSetPoint : REAL := 0.0;
rSpFlow_DeltaT_Si : REAL := 0.0;
MP_Address: MP-Bus address of the slave.
bStart: a positive edge starts the function block.
strDataKL6771: the data structure with which the KL6771 [
}
25] function block must be linked (see
DataKL6771 [ } 72] ).
dwPassword: the actuator password is usually 0x0000.
nControlMode: specifies the control mode (see E_MPBus_ControlMode [ } 69] ).
nDetaTLimitation: dT limitation (see E_MPBus_DeltaTLimitation [
}
69] ).
rSetPoint: dT limit.
rSpFlow_DeltaT_Si: flow at saturation.
VAR_OUTPUT
bBusy : BOOL;
bError : BOOL;
iErrorId : MP_Error;
bBusy: This bit is set for as long as the block is active.
bError: The output becomes TRUE as soon as an error occurs. The error is described via the variable
iErrorId .
iErrorId: The output issues an error code when an error occurs (see MP_ERROR [ } 70] ). Simultaneously
bError is TRUE.
