Then the problem doesn't involve PLC communication... The strange thing is that function WriteTags and ReadTags seem to do their job, but the error message appears anyway!!

If linked tag hasn't an initial value, the "Default value" is empty and this cause the error messages while executing functions WriteTags and ReadTags.
