César García commented on PLC4X-337:
------------------------------------
Hi liuqiang,
This type of problem is recurrent even using Siemens' own software (aka WinCC
or WinCC Flexible), this is because this type of writing must first verify if
that space is really reserved (in the first two bytes).
At another point, as Chris points out, the nomenclature you are using is not
correct.
I will be verifying this functionality.
What I do require from you is that you collaborate with the tests of the new
features of the driver and indicate the part numbers of your CPUs and the
firmware versions to document my testing protocol.
Kind regards,
