Re: Apache and mxProxy

It is not possible to proxy the mxProxy connections through Apache.
It is possible to run the mxProxy on a separate/DMZ host.
It is possible to use a reverse proxy for the WinCC OA webserver (for example with ULC UX).

Re: Server timestamp assign IEC104

The smoothing can be disabled for the general query by setting the '_Driver<num>.SM' to 1 (always smooth except for the general query).

The other values can be found in the documentation under: Reference tables -> Internal data point types -> _DriverCommon (General driver)

Re: GEDI

The "Insert Function Documentation" is NOT part of the "High Speed Programming", but built into the script editor. So unfortunately the inserted function header is fixed.

Re: Multidimensional arrays in OPC-UA client

It looks like multidimensional arrays are not supported. I guess it would be not too difficult to convert a multidimensional array to a flat array.

Contact support to create a feature request for this.

Re: DPEs update problem with S7plus

Is it not an option to use 'Polling on Use' instead of (de)activating the variables?

Look in the documentation under: Drivers -> Driver specific functions -> Poll on use

Re: Gateway-WinCC OA with TCP

Modbus does not work with strings, at most short character arrays. Because the Modbus message size is limited. The easiest solution would be to use MQTT and run a broker, like mosquitto . But if you want to implement and maintain your own protocol, it could also be done in control with tcpOpen/udpOp...
