How to use the pylogix.PLC function in pylogix

We'll start reading in a loop, in my case, I'm
reading a tag called PE040, which is a BOOL.
Once we see that the value is True, we'll call
FaultHappened(), then we enter another loop that
will keep reading until the value goes False.
This will make sure that we only call the function
once per True result.
'''
from pylogix import PLC
import time

def FaultHappend():
    # this should get called once.
    print('we had a fault')

with PLC() as comm:
    comm.IPAddress = '192.168.1.9'
    
    read = True
    while read:
        try:
            ret = comm.Read('PE040')
            time.sleep(1)
            if ret.Value:
                FaultHappend()
                while ret.Value:
                    ret = comm.Read('PE040')
                    time.sleep(1)
        except KeyboardInterrupt:
            print('exiting')
            read = False

Write to a custom size string

WHen you create a custom size string, it is essentially
a UDT.  We cannot write to them in the same way that we
can write to a standard size string.

In this case, we're going to write some text to the tag
String20, which is a custom string STRING20.  We not only
have to write the data, we have to also write the length.
'''
from pylogix import PLC

with PLC() as comm:
    comm.IPAddress = '192.168.1.9'
    string_size = 20
    text = 'This is some text'
    values = [ord(c) for c in text] + [0] * (string_size - len(text))
    comm.Write('String20.LEN', len(text))
    comm.Write('String20.DATA[0]', values)

'''
Read a tag in a loop

We'll use read loop as long as it's True.  When
the user presses CTRL+C on the keyboard, we'll
catch the KeyboardInterrupt, which will stop the
loop. The time sleep interval is 1 second,
so we'll be reading every 1 second.

'''
Write a program scoped tag

I have a program named "MiscHMI" in my main task.
In MiscHMI, the tag I'm reading will be TimeArray[0]
You have to specify that the tag will be program scoped
by appending the tag name with "Program" and the beginning,
then add the program name, finally the tag name.  So our
example will look like this:

Program:MiscHMI.TimeArray[0]
'''
from pylogix import PLC

with PLC() as comm:
    comm.IPAddress = '192.168.1.9'
    comm.Write('Program:MiscHMI.TimeArray[0]', 2019)
