Rules for Script Task Functions
These rules must be followed when writing a script task function:
The @TASK decorator must be on the line preceding the Python function. The
decorator is case sensitive.
The function does not take in any parameters.
The functions does not return any parameters.
The function may call into any other functions in the script. Those other functions do
not need to have the @TASK decorator.
19.3.3.
RS-232 Output Script Example
The following example uses a script task to send data out the RS-232 port. The example will read
the last value of measurement M1 and output it on the RS-232 port. It is expected that the
script will run on a schedule. Such a script could be used to drive a RS-232 display or to pass
data to another logger.
@TASK
def rs232_last_meas():
with serial.Serial("RS232", 9600) as output:
output.write(str(measure(1, READING_LAST)) + "\r\n")
output.flush()
19.3.4.
Setup Change Script Example
This script increases the measurement and transmission intervals, which results in more frequent
data collection and transmissions. It is meant to be run when the system goes into alarm. That
means the Script Task’s
Trigger
should be set to
Alarm In Only
.
