VAR_INPUT
MP_Address : USINT := 1;
bStart : BOOL;
strDataKL6771 : DataKL6771;
TMpolling : TIME := t#10s;
bRelay_R1 : BOOL;
bRelay_R2 : BOOL;
bRelay_R3 : BOOL;
iUa : UINT;
SETTINGS : UST3_SET;
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.
bRelay_R1: relay PIN 15.
bRelay_R2: relay PIN 16.
bRelay_R3: relay PIN 17.
iUa: analog output PIN 5 (1 mV = 1 digit).
SETTINGS: data structure for setting the scaling and the resistance measurement (see UST3_SET [
}
75] ).
VAR_OUTPUT
bBusy : BOOL;
bError : BOOL;
iErrorId : MP_Error;
iU1 : INT;
iU2_YSensor : INT;
iU3 : INT;
bDigital_S1 : BOOL;
bDigital_S2 : BOOL;
bDigital_S3 : BOOL;
iResistor : INT;
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.
iU1: Analog input PIN 3 (1 digit = 1 mV or 1 digit = 250 µV).
iU2_YSensor: Analog input PIN 4 (1 digit = 1 mV or 1 digit = 250 µV).
iU3: Analog input PIN 7 (1 digit = 1 mV or 1 digit = 250 µV).
bDigital_S1: Digital input PIN 8.
bDigital_S2: Digital input PIN 9.
bDigital_S3: Digital input PIN 7.
iResistor: Resistor value PIN 4.
