Description of issue

Writing strings individually works perfect but trying to write multiple Strings does not.

Examples:
[("MyString", "This is a String"),("MyDint", 10), ("MyInt", 3)]
MyString - Unknown Error 255
MyDint - Success
MtInt - Success

[("MyString", "This is a String")]
MyString - Success

[("MyString", "This is a String"),("MyString2", "This is a String2")]
MyString - Unknown Error 255
MyString2 - Unknown Error 255

Code

from pylogix import PLC
with PLC("192.168.123.100") as comm:
comm.ProcessorSlot = 2
request = [("MyString", "This is a String"),("MyDint", 10), ("MyInt", 3)]
ret = comm.Write(request)
for r in ret:
print(r.TagName, r.Value, r.Status)

Prints:
Unknown Error 255 for the string but everything else succeeds.

Any Ideas?

So it wasn't just me then...
Sweet, is that good to go then?

Not just you, legit bug. The latest update fixed it for me. Try it out and let me know if you agree.

When I try to upgrade via "pip install pylogix --upgrade" it is still showing up as 0.7.16, do I need to manually upgrade?

Instructions are on the readme. See screenshot below, you have two options clone as shown in the picture, or click the download button on the repo, then run the setup cmd:

I had to Uninstall and then Reinstall to pick up the change for some reason.
Anyway it works a treat, thanks for that.
