3.2.9.5.4 FB53 (ANA_OUT), giving the analogue value
With this data handling block FB53 (ANA_OUT) analogue values can be given out.
The following parameters are to be transferred when loading FB53:
Des. Format Explanation
ADR KF Peripheral base address of the building
block
K/OU KY Number of the channels/ analogue output
WERT W Output value
FEHL BY Error byte
Tab. 3-11: List of parameters for the loading of FB53
The following details are necessary for the abovementioned parameters:
ADR
(peripher)
Input of the peripheral address, under which the building block can be controlled
by the PLC. This address can be set with the DIL switches S1 and S2. Further
details can be found in chapter 5.
K/OU
K: Number of channels to which the module is connected (1-3).
OU: Number of analogue outputs (1-4, 9)
By 9, the VALUE is given out to all 4 outputs of the module.
WERT
Flag word, in which the analogue value is filed.
FEHL
This byte has a value of 0, if functioning correctly. In the case of a malfunction an
error code is entered. The error is acknowledged automatically, i.e. the byte is
reset to 0 once the cause of the error has been eliminated.
1 Building block not ready
There has to be an interval of at least 10 ms between access to the same
channel or else there will be a misoperation!
