Hi!
small question: Can MpDatabase be used with a certificate for encrypted communication? Doesn’t seem like it to me!
If the script is running on a different device than the PLC (NOT hypervisor), then the whole communication is freely accessible to anyone listening on the network. What is B&Rs solution to this, especially in light of CRA?
Best regards!
Marcel
Currently (as of mapp Services 6.7) it is not possible, as it requires adaptations on both the python script and MpDatabase to enable HTTPs communication. However, we are currently in the process of reworking and improving both MpDatabase and (primarily) the python script. The updated script will be a sample, including documentation on how to properly use, extend and secure it. “Sample”, because unfortunately we can not provide a “final” script due to (1) certain CRA requirements that require certain actions to be taken on the system the script is running on (e.g. using SysLog) and (2) keeping extensibility options like adding custom database types available for you (our customers/users), but we will try to make it as secure, “easy-to-use/extend” and well-documented as we can.
Currently, for HTTPs support, we are targeting mapp Services 6.8 (or mapp Services 6.9, in case we run into unsolvable/unexpected issues). So… Stay tuned! We will definitely mention it in our Version Information in the help and the RevInfo once this feature is implemented and available.
PS: I wanted to give a small teaser, but all I could have done is make a screenshot of a boring-looking terminal window or the not-yet-finalized help…
Hi Michael,
thanks a lot for the quick and detailed response!
Looking forward to it!
Best regards!
