Change userbits from PLC

[twinsen]

Is there a way to set a datapoint element's userbits from PLC?
I have a dpe read from a SIMATIC PLC, I want the dpe's userbits to be set/reset by that plc too.

There is no standard way to set userbits from a PLC. Drivers are designed to read/write values, depending on the protocol the value has additional (status/quality) information which could be mapped to userbits.
For example the following drivers can map information to the userbits: SINAUT, OPC (UA), IEC104, DNP3 & BACnet.

With a simatic plc it is also possible to use the open user communication for (UDP) communication with a control script, which could set the userbits.
