Hi!
This error keeps occurring every time I change a Siemens OPC Tag.
Has anyone ever experienced this?
Thanks

I deleted all my string tags and replaced them with character arrays.
This error has stopped occurring
how exactly did you add a character array? I am searching through forums and the ignition user manual and I cannot find a way to add an array of data type char. I am using a siemens s7-400 plc if that makes anything different
I addressed all the letters, one tag per letter, and then wrote a function to read as a string
def qrcodeChar2str(path):
l=[]
for c in range(1,11):
l.append(system.tag.read(path + "/qrcode" + str(c)).value)
s = "".join([chr(c) for c in l])
return s
thank you for a quick reply! what data type did you use for the tags? because I also cannott find CHAR type in the list of supported types
