6.2.10 MP_EV
This function block is used to control a control ball valve of series P6...W..EV-BAC. For more information
please visit
www.belimo.ch .
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 .
VAR_INPUT
MP_Address : USINT := 1;
bStart : BOOL;
strDataKL6771 : DataKL6771;
TMpolling : TIME := t#10s;
nOverrideControl : E_MPBus_Override := MPBus_Override_Auto;
nRelSetpoint : INT;
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: the relative setpoint nRelSetpoint is ignored in override mode (see E_MPBus_Override
[ } 70] ). Overriding is disabled if the command is not repeated within 120 minutes.
nRelSetpoint: the set value is interpreted either as position setpoint or as advance setpoint.
VAR_OUTPUT
bBusy : BOOL;
bError : BOOL;
iErrorId : MP_Error;
