IEC 104 - Driver

[EESF_VER]

Hello,

In version 3.18,

I have a redundant project and would like the IEC104 driver in my redundant project to be disabled, as it takes precedence over my primary project.
How can I ensure that the IEC104 driver is only active on the primary project?

Do you mean to just not start the IEC104 driver at the redundant partner?
In this case you could just change the start option of the driver manager to 'manual'.
Or do I misunderstand your question?

What is the use case overall?
Why would you want to ensure that the IEC104 driver is not active on both redundant systems?
The problem with setting the driver of one redundant system to manual mode is, of course, that a subsequent switchover would then cause a significant issue due to not receiving data.

In case you want only the active server connecting to the RTU, this setting is available since 3.18+P010.
.

138090/1-6594394371: For IEC 60870-5-104 driver it is now possible that only the active driver connects to the RTU.

This can be used for configurations, where the RTU accepts only one connection.

The behavior can be activated on the _IecConnection.Config.Flags DPE by setting the bit 11 (start counting from 0).
