bBusy : BOOL;
bError : BOOL;
iErrorId : MP_Error;
stUnit : STRING;
iOffsetCO2 : 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.
stUnit: C = °C or F = °F, ? = not read.
iOffsetCO2: OffsetCO2 [ppm].
rOffsetHumidity: OffsetHumidity [%] 0.01.
rOffsetTemp: OffsetTemp [°C or °F] 0.01.
rOffsetDewPointTemp: DewOffsetTemp [°C or °F] 0.01.
6.2.16 MP_Smoker
This function block is used to control and monitor a fire damper.
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, maximum 30 s. bError is used to indicate an error in communication with the
actuator. The type of the error can be read with iErrorID .
A positive edge at bReset clears any pending error messages from the actuator. A telegram is thus sent to
the actuator that acknowledges the errors in the actuator. If they persist, they remain set. This applies to all
bErr_* error bits.
bOpen_Close is used to open or close the fire damper. TRUE causes the fire damper to open, while FALSE
closes it. bOpen indicates that the damper is open, and bClosed indicates that it is closed. If both bits are
FALSE, the actuator is currently opening or closing.
