Pylogix about pylogix HOT 15 CLOSED

Are there any error messages you can share?
Are you calling .Close() after every read? If so, you should not, only call .Close() when you are done reading/writing.
What PLC are you working with?

I am unable to view your error, it appears that Avast has had it's way with it.

Please copy and paste the message directly here. Please also address the other questions I had.

One problem I see is that you are creating a new instance of PLC with each read. Try this instead:

from eip import PLC
import time

with PLC() as comm:
comm.IPAddress = '192.168.1.1'

while True:
    ret = comm.MultiRead("A","B","C","D")
    print ret
    time.sleep(0.5)

for some reason, I can't get the formatting right tonight...

I'm saying with your original code, you are creating an instance of PLC() each iteration of your while loop. This is not the way to do it. You need to create an instance of PLC(), set it's IP address, then in your while loop, read your tags.

Did you try the example I provided above?

Could I convince you to capture the error using Wireshark and email it to me?

edit: never mind, there is definitely something going on. I am looking into it.

Could you try a test for me when you get some time? Search for socket.settimeout and change both of them to socket.settimeout(5). This will allow for 5 seconds to receive data. See if that makes it more stable. If you do happen to wireshark the problem, please send it my way.

Did you have any luck with the change I suggested?

There is no solution. You must read each element of your structure individually.
